Sensebender Micro

BTW, what is the F() function ? instead of Serial.print("Sensebender Micro FW "); why using Serial.print(F("Sensebender Micro FW ")); ?

It's a way to save some RAM. A simple string constant like "Hello" takes up 6 bytes of RAM and also 6 bytes of Flash (program) memory (6 bytes includes a single "hidden" byte of binary zero as an end-of-text marker). At startup and before your code executes, that bit of program memory is copied to RAM. The F() thing is a "macro" which causes the compiler save only the 6 bytes of Flash (no Ram used). The print function can (through C++ typing) fetch those 6 bytes from Flash at runtime for printing. If you have long or many text constants in your program, this can add up to some useful savings,when you only have 2K of RAM.

See the "F() Macro" on this page: https://www.arduino.cc/en/Reference/PROGMEM

@tbowmo Good hint. But it is happening to all three sensbeners for at least one month now. (different orders). I now got 4 more so I will test again soon.

Over xmas I tested also with magnesium chloride hexahydrate. magnesium chloride hexahydrate produces exactly 33%rel.

All 3 sensbenders report exactly 39% or 40%. So they are also here 7% off. But almost the same value and very reproducible - so thats great!

[nivoc]

@tbowmo I'm now almost sure that my test-setup has no faults very reproducable and read many articles - I plan to verify my findings with someone who has a professional calibrated device.

I saw in a museum nearby that they have professional calibrated devices

So I will test against those

[tbowmo]

@nivoc

Have you tried to "bake" your sensebenders, in case they have been exposed to high humidity for a longer time?

They are, as far as I know, produced in a part of China, which are known to have very high humidity. (been traveling there a lot some years ago)

[Heinz]

@nivoc
I can confirm your results: I am running two different sensors in the same room next to each other. The sensebender is always above the dht-22. Right now it is
52% to 47.8% rel. humidity, while the temperature is 17.8 to 17.9 (which is nearly equal).

[nivoc]

@tbowmo No I haven't baked yet. I will try that but not in the next two weeks. But I will report back.

[nivoc]

But I tested tonight with distilled water - so should be exactly 100%. And again (I didn't know that thats possible) I got 104 and 107% so slightly above (still increasing). Thats great b/c that means all values are about 7-8% too high.
At 33% the reading was about 40%
At 75% the reading was about 83%
At 100% the reading was about 106%

So reading minus 8% gives a pretty accurate result. In the next few days i will test 3 more sensbender.

Distilled Water (100% expected):

[bjacobse]

Read the spec for the humidity sensor used in the sensebender (Si7021 integrated humidity / temperature sensor.)
Precision Relative Humidity Sensor: ± 3% RH (max), 0–80% RH
To my reading this is actually 6% wrong reading to one of the sides - so when you are measuring yours to be 8% off, is caused that you are using the device outside of humidity range 100% and max is 80%

Link to spec:
https://www.silabs.com/Support Documents/TechnicalDocs/Si7021-A20.pdf

What I want you to know, if your device is reading within 6 % of the value - it's still reading correct. and when you compare ex DHT22 that device also have some reading variation error. Do not expect to get 100% perfect value for 2 devices...

[nivoc]

@bjacobse Yes and no

Yes 100% is outside of the spec.

And no. 33% with Magnesium Chloride Hexahydrate is inside the spec and I get 40% instead of 33-34%.

Max off should be 3% above or? Means 37% - but fair enough. Should be ok for household use.

I hope the Temp measurements are not off by that much.
i don't need .00001 accuracy or anything. but i feel a big difference between 70 and 72 in my house.

[bjacobse]

@mvader
Spec is: High Accuracy Temperature Sensor ±0.4 °C (max), –10 to 85 °C
So the temp accuracy is quite good

[bjacobse]

@nivoc
Yes you are right, +-3 from your humidity solution on 33%, then the reading could be in the interval 33-3=30% or up to 33+3=36% and should not show 40%

did you get same false readings from other sensebender humidity sensors?

[nivoc]

@bjacobse Yes I have 3 sensbener running from 2 different orders. All 3 are very near by each other. So at 33% they all read something near to 40%.

I have 4 more sensbenders to build. However I continue to test tonight with a Boveda-Pack that claims to bring the hum in a containter to exactly 69%. I did 4 test's so far and also used different technics. So i get more and more confident.

But the very good thing is - it looks every reproducible. So the value may be off but reproducable accurate off by about 8%. When I completed my test it will be very easy to correct it within the software.

[nivoc]

@mvader I haven't made any very accurate temp testings. But the readings are exactly the same than other non-sensbender devices in my home. I started researching the humidity b/c I had different readings between different devices.

Temp looks fine to me.

[tcontrada]

What is the current consumption of the Sensebender during sleep and active modes?

Thanks,
Tony

[tbowmo]

@tcontrada

there are some measurements in the old design thread here http://forum.mysensors.org/topic/510/minimal-design-thoughts

[nikos1671]

Hi. What case you all using for the sensebender ?Any good idea.

[filipq]

[tbowmo]

@filipq

Where did you find that box?

[filipq]

@tbowmo

Got it from http://cpc.farnell.com/1/1/57932-evatron-pp42m-case-sensor-ivory-71x71x27mm.html.
Not the cheapest, but definitely worth the money as it is very good quality. There are other colours available (white and black) https://www.jprelec.co.uk/store.asp/c=552/Gas-Sensor-Case

[scalz]

@tbowmo: I have some of these too, it's nice box. i got these from tme. cheaper

[ahmedadelhosni]

Hello @tbowmo

Doesn't the atmega328 has only 2 pins which are D2 and D3 from external interrupts ?
I am wondering why do we waste the usage of D2 since the IRQ pin is not used in the library ?

[Anticimex]

@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.

[tbowmo]

@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..

[hek]

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

[ahmedadelhosni]

@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.

[tbowmo]

@hek

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

[Anticimex]

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.

[ahmedadelhosni]

@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.

[TheoL]

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!

[user2334]

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 (=25µA) 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);
}

[mfalkvidd]

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

[ximinez]

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.

[tbowmo]

@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.

[Anticimex]

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.

[ximinez]

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

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.

[tbowmo]

@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..

[ximinez]

@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.

[Anticimex]

@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.

[ximinez]

@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.

[Anticimex]

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

[ximinez]

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

[Anticimex]

@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

[ximinez]

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

[tbowmo]

@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..

[ximinez]

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

Serial output now looks like this: "Sånsebåndåò Micro FW 1.3" with random characters corrupted. I think I've killed it
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)

[Anticimex]

@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.

[ximinez]

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)

[Anticimex]

@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.

[ximinez]

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.

[Anticimex]

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?

[ximinez]

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?

[ximinez]

Fails with the same errors on Uno for me.

[Anticimex]

@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.

[ximinez]

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

[Anticimex]

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.

[ximinez]

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

[Anticimex]

@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.

[ximinez]

Got it now
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?

[Anticimex]

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.

[ximinez]

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?

[Anticimex]

@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).

[ximinez]

@Anticimex Yeah, that's what I asked

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

[Anticimex]

@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.

[ximinez]

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

[Anticimex]

@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.

[ximinez]

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:

Sôártinç óensor (RÎONA-, 2.0.0-beta)
Raäio init æáiìåd. Ãèeck wiring.

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

[Anticimex]

Sounds good. Bedtime here too.

[ximinez]

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().

@ximinez

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

[ximinez]

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.

[ximinez]

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.

[Anticimex]

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 (=23µA) 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, ...

[ximinez]

@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?

[Anticimex]

@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.

[Anticimex]

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

[ximinez]

@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.

[Anticimex]

@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.

[ximinez]

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?

[ximinez]

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

[ximinez]

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?)

[Anticimex]

@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...

[ximinez]

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.

[Anticimex]

@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.

[Anticimex]

@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.

[tbowmo]

@ximinez

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

[gloob]

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?

I'm using a Mac if it is important.

[alexeinz]

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 ?

[hek]

@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

[alexeinz]

@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 )

[hek]

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

@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.

[alexsh1]

@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.

[Anticimex]

@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.
