Sensebender Micro


  • Contest Winner

    @ahmedadelhosni because it is not in use by the library <yet>. Would be a shame if the library some day gets updated with support for a radio that can enter low power sleep and still wake when needed.


  • Admin

    @ahmedadelhosni

    What @Anticimex said.. And at the time when I created the sensebender, I didn't know that the interrupt wasn't used (I was relatively new to the project) so I thought that we had to have it connected..


  • Admin

    It is used by the RF69, right @tbowmo? (when using adapter plate...)



  • @Anticimex @tbowmo This a valid point which I thought of but I needed two interrupt pins. As far as I knew from fast searching is that external interrupts which react to CHANGE in pin state are only valid for pins 2 and 3. Correct ?
    Maybe there is another solution which I missed.


  • Admin

    @hek

    Yes, that's right, RFM69 is using interrupts.. (and rfm69 is possible on the sensebender using for example this pcb)


  • Contest Winner

    And with a scalpel and a soldering iron you should be able to use both interrupts by disconnecting the one reserved for nrf24. Of course that would disable the use for rfm69 om that board.



  • @Anticimex Yeah I could just connect my device to the atmega pin directly as I can see/find any pin header to route the interrupt pin 2. They are all used.

    Thanks guys.


  • Contest Winner

    I just received two sensebenders. I'm really impressed by the great engineering behind the board. I can't wait to heat up my soldering iron. I love them!



  • I just received two Sensebenders, but have problems getting the device to consume little power. I get totally different values as displayed above.

    With the following sketch, I get about 5,6mA in active state and 1,6mA in sleep mode with nRF24 attached. I have compared different nRF24-chips and this one consumed the least power.

    Without the nRF24, I get 4mA and 0,025mA (=25ยตA) during sleep mode.

    #include <LowPower.h>
    #include "RF24.h"
    
    RF24 radio(9, 10);
    
    void setup() {
    }
    
    void loop() {
        delay(8000);
        LowPower.powerDown(SLEEP_8S, ADC_OFF, BOD_OFF);
    }
    

  • Mod

    @user2334 I don't think the LowPower library shuts off the radio. Use MySensor's sleep function instead.



  • A general question regarding these types of boards that are generally designed to be used on battery power. Is there a reason to not power the ATSH204A and Si7021 from AVR pins? The pins can source far more than what these devices can sink (even when using the heating on the Si7021), and it would allow squeezing a tiny bit more out of the battery life by selectively powering down the devices.
    Eg., if I'm not using the ATSHA204A at all, I can save 150nA continuous current. The power saving from disabling the Si7021 is less at about 60nA, so that might just be eaten up by having to wait up to 80ms before a full conversion.

    I'm aware that we're talking about saving a tiny ~200nA here, but over the span of two years that adds up to about 350mAh.

    So what I'm wondering is simply, is there a technical reason saying that this really isn't a Good Idea (tm)? Should I avoid doing so if I design my own similar device?

    I second that question. I was just thinking about a similar idea.


  • Admin

    @ximinez @LastSamurai

    That is indeed a good question. The straight answer is that I didn't think about that when I designed the board.

    In theory you could also power the radio from a digital pin on the avr, and power that down completely.

    BTW. If you turn on the heating element in the si7021 at full power, I think the power drain exceeds what the avr can deliver on a digital pin. But one could just avoid that.


  • Contest Winner

    I have been thinking about this as well. But I discarded parts of the idea because I needed the IO for other stuff (MYSX in my case). Instead I designed a switched rail where one could attach sensor power sinks. It's not io powered but it is io controlled.
    Though I did not attach the si or atsha to this switch function as I decided to make it an optional feature but wanted to make sure authentication and temp/hum would always be available.



  • That is indeed a good question. The straight answer is that I didn't think about that when I designed the board.

    Oh, I thought it was a design decision ๐Ÿ™‚

    In theory you could also power the radio from a digital pin on the avr, and power that down completely.

    I've been wondering about the radio in particular. Does the radio keep any state locally, and will it have to be reinitialized upon powerup?

    BTW. If you turn on the heating element in the si7021 at full power, I think the power drain exceeds what the avr can deliver on a digital pin. But one could just avoid that.

    The heating element eats a measly 3.1mA according to the datasheet, so even that would be well within the limits for a single in on a 328p.

    Now, I don't have Eagle installed on this laptop, and my bandwidth is limited right now. Is there a picture of the PCB traces available? Wondering if atleast some of this can be hacked on by cutting traces.


  • Admin

    @ximinez

    Nope, there are only the eagle design files.. (Or gerbers, you could use a gerber viewer)

    I have 4 sensors operating for almost a year on two AA batteries, they all report around 73% battery left. So in my opinion, it's not that necessary to do extra optimization on the power drain..



  • @tbowmo
    While 73% after one year is good, it doesn't mean that it can't get better. The ATSHA204a and Si7021 draw about 350mAh from the battery over two years from idling alone. The NRF24L01+ draws around 1500mAh.
    Remember, you will never get close to emptying out the battery before the voltage drops below working voltage. Using alkaline batteries, you'll get around 2000mAh before the batteries reach 2v (which, if you're using battery voltage as a pure percentage, is 66%), at which point the voltage curve drops sharply - and your sensors die. The radio and sensors have drawn more than 900mAh from your battery during the year you have run the device (and that's just idling) - close to half your battery life.

    Assuming your battery percentage is correct, and you started at 100% one year ago, I'm betting your sensors will die sometime during this summer. While you may think that extra optimization isn't worth it, I do. The nanoAmp draws may not seem like much, but drawn out on a timescale like this, it is a major power draw.


  • Contest Winner

    @ximinez That depend on how you define battery percentage. I have chosen to adjust my measurements to let 0% mean when voltage drops below the highest requirements of the onboard devices. Since that particular device will fail when voltage goes lower, it serves no purpose to provide a false battery percentage. 0% is when the node no longer operates according to specs. But this is of course hw/sketch-dependent.



  • @Anticimex The point still stands however. The discharge graph is far from linear, and your sensors and radio have already drawn close to half of your battery life by idling alone. A colleague of mine has had to replace the batteries in his two sensors already.


  • Contest Winner

    @ximinez I do not recall sharing my statistics, so I assume you refer to @tbowmo's stats?



  • @Anticimex Ah, yes. sed /your/@tbowmo's/g. I blame lack of caffeine.


  • Contest Winner

    @ximinez makes sense. I'm sure you can cut down on power consumption by cutting power to those peripherals. I do not know how signing would be affected by this though, as I have not tested it with switching the atsha on and off between calls. I would like to hear from you on that topic if you choose to try it though ๐Ÿ™‚



  • Ok, I've been looking at the image and my spare sensor. It looks like:
    Power to the NRF can be cut between C3 and VCC pin.
    ATSHA204a power can be cut on the trace that goes from the atsha and beneath the flash.
    Si7021 power can be cut at the trace that goes from C4.

    I just might have to dig out my scalpel and iron for this. If the components magically work without any extra initialization on powerup, modifying the code looks easy.

    I'll report back with my findings


  • Admin

    @ximinez

    For my battery reporting, I have set 1.9V as 0%, 3.3V is 100%..

    While you're at it, also power down the external flash, as it might also contribute a bit..



  • Well that went south pretty fast. Was wondering why my sensebender was acting up. Took a while to see that I had plugged in an ESP8266 module instead of one of my NRF24 modules. Those modules look far too much alike ๐Ÿ˜ก

    Serial output now looks like this: "Sรฅnsebรฅndรฅรฒ Micro FW 1.3" with random characters corrupted. I think I've killed it ๐Ÿ˜‰
    I can still flash firmware to it via serial, so it's not completely dead.

    I can however confirm that both the SHA204A and SI7021 self-tests OK being powered on in-sketch:
    (Flash seems to randomly fail or test OK, not sure why yet)

  • Contest Winner

    @ximinez If possible, try to check if signing and verification of signatures work as well. I have tried to implement the use of the ATSHA to be atomic in nature, but it could be that some state is retained which is cleared on power down which might break the calculations.



  • What is the easiest and fastest way to sign and verify? I don't have a gateway set up quite yet.
    (And, is any part of setting this up dependent on serial integrity? If so I might have to adjust baud quite a bit)


  • Contest Winner

    @ximinez Well, without a gw the only option is to use node peer to peer transmissons to test signing. How to do it is described in the signing documentation, assuming you use development branch, you can see here. For master, look here.



  • I have an Uno with an ethernet shield and nrf24 hooked up, so I will have to get around to write a sketch for that purpose.
    But to get signing to work, I'll have to personalize the atsha? That sketch doesn't compile for me.


  • Contest Winner

    Yes, you have to personalize it. What is failing? I don't have an Uno myself, but according to Jenkins the personalizer compiles ok for Uno on both master and development. You don't have any local changes?



  • The personalization fails to compile for my sensebender micro. There's a few undeclared:

    Personalizer:225: error: 'EEPROM_SIGNING_SOFT_HMAC_KEY_ADDRESS' was not declared in this scope
    Personalizer:225: error: 'hwReadConfigBlock' was not declared in this scope
    Personalizer:236: error: 'EEPROM_SIGNING_SOFT_SERIAL_ADDRESS' was not declared in this scope
    Personalizer:247: error: 'EEPROM_RF_ENCRYPTION_AES_KEY_ADDRESS' was not declared in this scope
    Personalizer:697: error: 'hwMillis' was not declared in this scope

    I'm trying to compile this against master however. Do I have to have dev branch to compile that sketch?



  • Fails with the same errors on Uno for me.


  • Contest Winner

    @ximinez and you are certain you have no local changes to the code? Jenkins builds both master and development branches every night for both the SenseBender and the uno and it builds all examples, including the personalizer without issues.



  • Pretty sure.
    I'll wipe my library dir and redownload master.


  • Contest Winner

    If memory serves me, some of the errors you get seem to originate from code on development branch. The eeprom addresses are to my knowledge not yet available on master.



  • Ok, moved from master to dev. Sketch compiled. Not quite the output I expected however.

    EEPROM configuration:
    SOFT_HMAC_KEY | FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF
    SOFT_SERIAL | FFFFFFFFFFFFFFFFFF
    AES_KEY | FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF


  • Contest Winner

    @ximinez it is the output I expected. You have gone for soft signing, and you see the reset values of the eeprom. You need to pick atsha settings. The link I gave you gives the exact settings to personalize both for software and atsha backends.



  • Got it now ๐Ÿ™‚
    I had two different sketches and had edited the wrong one. Now I have actual values.
    Is there an example GW sketch that I can load quickly to my Uno/W5100 shield/NRF24?


  • Contest Winner

    ๐Ÿ‘
    I'm rusty on the gateways. But on development branch, configuring signing is easier than on master branch. My link gives the details on signing configuration for both nodes and gateways with examples.



  • Yeah, I'm struggling a bit with those instructions. I've set up my gateway with soft signing, and got sane values written to EEPROM.
    Now, do I need any of the three values to personalize the sensebender?
    SOFT_HMAC_KEY?


  • Contest Winner

    @ximinez the SenseBender you have patched/cut needs atsha personalization, so no SOFT anything. But you need to have the same hmac key stored on the atsha on the SenseBender as you have picked as soft hmac key in eeprom of your gateway (the node you have personalized for soft signing).



  • @Anticimex Yeah, that's what I asked ๐Ÿ˜‰

    I get:
    Writing key to slot 0...
    Data lock failed. Response: D3


  • Contest Winner

    @ximinez locking data is a very bad idea. It will prevent you from changing the hmac key. You only need to (and should) lock configuration. Only lock data if you really know what you are doing.



  • Writing key to slot 0...
    Data not locked. Define LOCK_DATA to lock for real.

    Personalization is now complete.
    Configuration is LOCKED
    Data is UNLOCKED


  • Contest Winner

    @ximinez looks good. You should be done with personalization. Remember to require signatures from the SenseBender in addition to "enabling" it. You can also require signature on the GW, thus forcing all communications between them to be signed. The serial console will reveal how it goes. You can enable verbose debug (MY_DEBUG_VERBOSE_SIGNING) for the signing if you want more details on the signing parts.



  • I have the sensor sketch mostly done, but I'll have to do some soldering again tomorrow. It looks like D7 got burnt when I plugged in my ESP8266, giving ~0,5v out on that pin. Will have to work around that:

    Sรดรกrtinรง รณensor (RรŽONA-, 2.0.0-beta)
    Raรคio init รฆรกiรฌรฅd. รƒรจeck wiring.

    When that is OK, I'll look at the GW sketch.


  • Contest Winner

    Sounds good. Bedtime here too.



  • D3, D4 and D7 are all funky, and do not give ~3v when set high. So I'm back to the radio being on all the time.
    D5 and D6 mysteriously work just fine.

    Radio is now OK, but the sensebender reboots before it gets to setup().

  • Admin

    @ximinez

    Sounds like it's on its way to the "other side"..



  • Yup. Setting up my other sensebender as a proper signing sensor and my uno as a gateway. This will have to wait until I get a couple more working sensors.



  • Ok. I set up my GW, and set up my healthy sensebender as an outdoor sensor. The zombie sensor is now a working indoor sensor.
    I have enabled signing and set up whitelisting, but enabling signing debugging makes the sketch oversize, so I can't actually check if signing works - but atleast now I have two sensors.

    Domoticz up


  • Contest Winner

    You will still be notified without verbose logging. And if you have enabled and require signing, you won't get any data if something fails (assuming signing is properly activated).

    As a follow-up to my previous posting, I can confirm, that using original nRF24-modules (best source seems to be https://www.itead.cc/nrf24l01-module.html), I get 0,023mA (=23ยตA) with nrf24 attached during sleep mode (no difference between the libraries JeeLib->Sleepy::loseSomeTime or LowPower->LowPower.powerDown).

    It is quite interesting, that so many nRF24 Modules (bought from eBay, from Amazon UK) are clones with higher power consumption. Some of them use 3mA, some have electrical short, ...



  • @Anticimex I've set MY_SIGNING_SOFT, MY_SIGNING_REQUEST_SIGNATURES and MY_SIGNING_NODE_WHITELIST on the GW, and reenabled (normal) debug but not signing debug since that is too big.
    With those enabled, if the sending node does not sign, I should not get this?

  • Contest Winner

    @ximinez The GW will only require signatures from a node that in turn require signatures.
    It is the sg-flag that indicate if a message is signed, in your case, both messages are unsigned.
    If you only have node->gw communication, both gw and node has to require signatures for you to see signed messages.
    If you have gw->node communication, it is enough that the node require signatures, the gw will then sign them, no matter if the gw require signatures or not.

  • Contest Winner

    @ximinez Hm, good, but I still see no signed message. But at least a nonce was sent



  • @Anticimex Sensor values are getting through though. And signing is requested on both ends (for one sensor so far). I can't see any other #defines that should be set to enable signing. I get the same result on both the zombie sensor and the unmodded one.

    I get three "sign fail" (showing up as verify fail on gw) before the sketch reaches setup(), where the ATSHA gets powered up. I will need to power the ATSHA somewhere in the mysensors library. However, once setup() is reached, the ATSHA seems to handle powering down and up just fine.

    I can however say that it the Si7021 doesn't like being powered off and back on again after sleep. That causes the MCU to reset.


  • Contest Winner

    @ximinez Ah, yes, on development branch the signing backend clear the sign flag when it verifies the message. so it will always show as 0 without verbose signing debug enabled.
    I know there have been discussions about a "pre setup" to be used for early sketch init. You probably want to power the atsha for early handshaking as well to get the sketch name and such to propagate properly. @hek perhaps has the latest on such features.



  • I've built a nicer-looking serial gateway instead of the rather large ethernet gateway. I thought that would basically be a "slot-in" as long as I personalize the GW it with the same SOFT_HMAC_KEY, SOFT_SERIAL and AES_KEY as the original GW. Are there more steps that need to be taken to get the sensors to connect?

    Serial Gateway



  • No matter what I do now, this is what I get:

    send: 2-2-0-0 s=1,c=3,t=16,pt=0,l=0,sg=0,st=fail:
    sign fail

  • Contest Winner

    You must not use the same serial across nodes. Serial have to be unique. HMAC have to be identical.



  • Yes, I know serial must be unique. Serials go in the whitelist for the corresponding node ID. It turned out to be the NRF24L01+-modules with antennas. Replaced it with a regular module and it worked fine.
    (Which is strange, because one of those modules worked fine on the ethernet gw. It doesn't eat that much power does it?)


  • Contest Winner

    @ximinez The signing failing is due to messages not arriving (st=fail). So it is not signing that is your problem here.
    However, with signing, messages are now "full size" which strains the RF link so if it is "weak" fewer messages get through if they are "longer". I suspect that is the problem here. Basically the usual stuff; adding caps, using a dedicated regulator and so on...



  • Looks like it works now, but what's the deal with the initial failed signs? Look at http://pastebin.ca/3585005 (GW side) and http://pastebin.ca/3585014 (Sensor side. Not the same powerup). It starts by failing a lot, then after a while everything looks OK.


  • Contest Winner

    @ximinez difficult to say. Maybe a long stabilization period for the regulator. You could try to add a delay in early init in the library to see if it makes a difference.


  • Contest Winner

    @Anticimex and again, it is not failed signature errors per se. It is st=fail (transmission errors) that cause the signing backend to timeout. So it is not the performance of the atsha (or sw) that cause the issue here, it is the radio.



  • @tbowmo said:

    @ximinez

    While you're at it, also power down the external flash, as it might also contribute a bit..

    I forgot about the flash. That would require bootloader support though? Or is the OTA done by jumping to the bootloader while running, keeping pin states?
    I'm waiting for some SOIC breakouts in the mail. When I get them, I'll scavenge the ATSHA and flash module from my zombie sensor and build my own sensebender with blackjack and hookers.


  • Admin

    @ximinez

    Yes.. bootloader should probably by modified, if you decide to switch off the flash as well..



  • I did update the Arduino IDE and now I don't see the Sensebender Micro in the device list.
    I'm using 1.6.5 and did copy the content to the boards.txt.

    Is there something else I have to do?

  • Is it possible to use the ftdi or isp vcc / gnd to connect a pir ?
    or do i need to source separate power and gnd for pir ?


  • Admin

    @gloob
    Maybe a little late, but the Sensebender is now available to be downloaded directly in the IDE using board manager.
    https://github.com/mysensors/ArduinoBoards

    @alexeinz
    You can use the same power/ground plane (and any of the digital inputs). Also note that the pir might need to be modified to handle 3v3.
    https://forum.mysensors.org/topic/1088/battery-powered-pir



  • @hek ...so to clarify , I can use the VCC and Ground of the ISP portion to power the sensor?
    ( my pir already modded for 3.3 )


  • Admin

    Yes, it doesn't matter. GND/VCC is the same no matter where you pull it on the board.



  • @Anticimex
    @ximinez said:

    Looks like it works now, but what's the deal with the initial failed signs? Look at http://pastebin.ca/3585005 (GW side) and http://pastebin.ca/3585014 (Sensor side. Not the same powerup). It starts by failing a lot, then after a while everything looks OK.

    I have exactly the same problem with Ethernet GW (Mega + Ethernet shield) + Sensebender:

    @alexsh1
    I am afraid I have to repeat what I have also said to other on the forum having problems with signing;
    you do not have problems with signing, you have problems with radio (st=fail). As long as you have st=fail, signing will not work reliably. It will not be less secure, but it will not let messages through.

    It is easy to suspect singing, because it might very well work better with signing off, but the reason for this is that signing uses the entire maximum message payload, and this makes it "harder" for the radio to send all the bits correctly, thus increasing the chances of a st=fail in case the link is not reliable.



  • @Anticimex I agree with you, but I find it interesting that sending a message fails exactly 9 times every time the node starts. I have changed different nrf24l01+ modules, put the transceivers close / far - it made absolutely no influence at all. 9 times st=fail and then everything works as expected.


  • Contest Winner

    @alexsh1 yes, it seem an odd coincidence. But I see nothing that signing can do about it I am afraid. st=fail means a message was not confirmed to get delivered properly and signing can't handle message drops. For security reasons, I have decided to not support retransmissions of nonces. If it can't be delivered, the entire signing session is considered compromised and have to be restarted with the exchange of a new nonce.



  • @Anticimex said:

    @alexsh1 yes, it seem an odd coincidence.

    It is even more interesting that I have zero st=fail after nonce is received .
    I can probably change the GW settings and the channel to make sure this is not causing any issues, but 9 st=fail in the beginning every time is a strange coincidence.

    @ximinez Did you manage to get it sorted? How many st=fail do you have in the beginning?
    Anyone else is having similar issues?


  • Contest Winner

    @alexsh1 Perhaps a long stabilization time for a power supply or clock on the node or gw cause it. You could try to add some delays and see if it is time-after-power-on that is the issue or whatever it might be. It is not signing in any case, because it is the node sending that reports st=fail. That is a rf issue. It always is. The nonce has been generated as it should, and the signing backend trusts the transport layer to handle the transmission of the databuffer, and in this case the transport layer reports back that it could not.



  • @Anticimex Just an idea - could it be that nonce is not generated in the beginning and requires some time? I'll do some testing tonight

    @alexsh1 No, nonces are being generated:

    and the generated nonce is not transmitted correctly (st=fail) due to some transport issue.



  • @Anticimex said:

    Than I am out of guesses - I cannot explain why st=fail comes up.
    FYG, I tried it without signing and it works just fine. No st=fail.
    There must be something between signing and transportation or transportation after signing?


  • Contest Winner

    @alexsh1 like I said, signing is not in itself the problem. The problem is that big messages are failing. You can just try by generating big messages yourself and you will get the same problem. I know this by looking on what generates st=fail and it is the transport layer. Signing generates the data to be transmitted, and this data is printed and shown to be correct. Bigger messages require more reliable communications. Shorter messages has a better chance of being transmitted correctly. It is that simple. Many have reported the sake issue and have solved it by improving radio power decoupling, rearranging the sensor placement or improve the power supplies.

    1. powering GW/Sensobender from a different source (battery, USB, PSU - 12V in case of GW, 5v in case of sensebender via LDO)

    2. swapped a few radios. Most of these are from working nodes with caps soldered. Maybe I should try completely different ones from a different batch? I mixed up three batches with no improvement.

    3. Tried to place GW and the sensebender 1m/5m/10m apart

    4. GW radio is powered via the AMS1117 3.3v

    So far it is the same result. Not sure I can come up with anything obvious unless you can suggest

    @alexsh1 sorry, I have not much else to suggest except experimenting with delays to see if the issue with failed transmissions at node startup can be avoided. I am no specialist on the radio. I'm the security guy and I see no wrong with the behaviour of those parts so I am short of any more useful suggestions I am afraid.

    @alexsh1

    When did you last update the library (on the gw)? @Yveaux recently added a irq-based de-queuing from the radios FIFO. It could help on improving things.

    Otherwise the only advice I have is to skip any amplified radio on gateway (if you have) and tweak powering of radio power on gw.



  • @Anticimex Well, at least we are fine on the security part ๐Ÿ™‚
    I'll experiment more on the radio part when I have time - why there are only 24h in a day? (rhetorical question)

    I downloaded the dev on 26/05 so it is very recent.
    I have normal radios both ends, but the idea is to have amplified one on the GW as well and change rf24_pa_max. Additionally, I'll try to mix as many radios as I can have. Who knows?

    To be honest, things were working OKish before as I took it seriously decoupling radios etc. This voodoo dance around radios really irritates me. Life is too short to waist it - I am now thinking seriously switching to RMF69W or probably to RFM95* (Lora)

    @alexsh1 yesh i have bashed my head on rf24 stability myself and have decided to base my network on rfm69:s instead. Too much chatter @2.4ghz. I hope the 69:s have better range and they also have the bonus of AES encryption in hw if you want to obfuscate the communication some. Signing adds netter security, but the paranoid can combine signing with encryption ๐Ÿ™‚ (yes rf24 can use AES encryption in software, but that cost memory and some overhead instead)



  • Whatever I did, did not help to solve st=fail

    When I disable signing I have got the following (not a signle st=fail):

    Starting sensor (RNONA-, 2.0.0-beta)
    Radio init successful.

    I am going to try different channels now with signing


  • Contest Winner

    @alexsh1 yes, without signing your messages are significantly shorter, and thus have a better chance of getting through. You can try experimenting with amplification as well.


  • Mod

    @Anticimex just a noob question: do you have an idea of the performance penalty of (software) signing? Any benchmark figures?


  • Contest Winner

    @Yveaux no, sorry have not got around to compare them. But software signing is actually quicker due to the single write bit banging for the atsha204a. One way to see the difference is measuring the delay for an ACK to come back from a node that require signed messages. I have no figures, but a node with software signing responds slightly faster.


  • Mod

    @Anticimex But is it significantly slower than without any signing?


  • Contest Winner

    @Yveaux yes. But I know that significant improvements can be made in the nonce whitening. It incrementally calculates a hash which is which is far less efficient than calculate the hash of a buffer. So there are room for improvements. I just wish there were more time, and now my arduinos are packed down so I wont be able to test. But volunteers are welcome, I can still code ๐Ÿ™‚

    Do you think a message size has anything to do with st=fail?


  • Contest Winner

    @alexsh1 yes, like I have said here and in other topics, signing often gets the blame for transmission problems because with signing the maximum message buffer is used, and larger messages are more difficult to transmit than short ones. So if you have a poor connection, odds are that a larger message will fail more often than a short one.

    I do not think its signing, but I think it is implementation of signing and sending.
    I do not get st=fail after the initial 9 messages not even once. Something is just very-very odd.



  • I'm seeing the same failed signings when the device powers up, but it doesn't fail after those.
