💬 Sensebender Gateway

@Magnus-Pernemark if you are on master, yes, then a node has to require signing to make the GW require it. On development (beta) gw will require signatures from everyone if it is set to require signatures (unless a specific flag is set).
Doxygen holds the the current documentation for master and development.

[alexsh1]

@Magnus-Pernemark I would suggest you move the signing discussion into a corresponding thread. Other people may benefit reading what you have gone through 😁

[Anticimex]

And yes, if you have nodes "exposed" you should make sure those are using atsha204a backed signing if you are afraid they might get physically abused.

[Anticimex]

@alexsh1 @Magnus-Pernemark indeed. There is a long running one here: https://forum.mysensors.org/topic/1021/security-introducing-signing-support-to-mysensors/

[magpern]

@Anticimex @alexsh1 yes should be in other thread. It started with a gateway question and migrated to a signing question. This will be the last one here, since I give up now. I will focus on building a network, and secure it later.

I'm on development branch, so I guess I just need that "specific flag". Couldn't find it in the documentation. I have it set up as the document in doxygen says, and GW should reject unsigned messages or wrong signing, documentation says, but it doesn't... Even nodes that have a different key and MY_SIGNING_ATSHA204 set, talks to the GW and reports temp.

I'll wait until beta is released

[alexsh1]

@Magnus-Pernemark
This is very simple. On the dev version:

GW (assuming you have atsha204 or use soft signing?)
MY_SIGNING_ATSHA204
MY_SIGNING_REQUEST_SIGNATURES

On a node (assuming you have hardware atsha204?):
MY_SIGNING_ATSHA204

This is it.

[Anticimex]

@Magnus-Pernemark why do you need the special flag? I just wrote that you only need that if you DON'T want your gw to require signatures from everyone. It works just like @alexsh1 wrote. And it will work like that on both bets and release after release so if you can't get it to work on beta now, it won't work on release later either.
I suggest you start posting some logs so I can see if you really have signing enabled and that all required handshaking takes place. But don't post it in this thread please.

[magpern]

@Anticimex @alexsh1 It's working now! In one of you replies (@Anticimex ), you misspelled the flag name, and I copy / pasted what you wrote. So all this time, signing was never activated. Now it is and gateway works as expected!

[Anticimex]

@Magnus-Pernemark oh, sorry about that. But I do hope the ones in the docs are correct. Good that it works now :+1:

This may be a beginner-misunderstanding, but i hope you can assist me.

I had to move one of my repeaters to improve the WAF of my sensor installation.
In this process i may have messed a bit too much with the routing as i think the nodes responds directly to the gateway, but the gateway answers through the repeater. The repeater is moved, and the signal does no longer reach the node, resulting in a head ache (FPAR fails).
I read the debug-section and I think i need to clear my eeprom to allow for a new routing to happen.

This proved more difficult than I had anticipated. below is my software stack/process:

• Downloaded Arduino 1.8.3 for non admin install
• Downloaded Mysensors Library v2.1.1 using Library manager
• Downloaded Arduino SAMD Boards (32-bits ARM cortex-M0+) version 1.6.11 using Boards manager
• Downloaded Mysensors SAMD Boards version 1.0.4 using Boards manager

I then rebooted my machine for good measure and uploaded the ClearEepromConfig-example to the gateway. No output in the serial monitor.

I then searched a bit on the forum and added:

#if defined(ARDUINO_ARCH_SAMD)
    while (!Serial) {} 
 #endif

In the setup()-part. This enabled me to get some output from the gateway. Unfortunatly it only returns Started clearing. Please wait...

I then did some more digging, and apperantly i2c_eeprom_read_byte() fails. So i searched some more on the forum and found I2C eeprom write fix for SAMD. So i tried the above once again but this time with Mysensors Library v2.2.0-beta (dev branch) just to see if anything changed. It didnt.
What did i miss ?

[Fabien]

Hi,
After weeks of tests, it doesn't work well with ethernet and RFM69HW. Every 2 days, I need to power off and on the gateway. Controller can't connect (OH2).
for some reasons, serial doesn't work on my odroid C1 with openhabian.

[korttoma]

Ever since lightning took out my original RFM69 W5100 GW I have been having trouble with the replacement GW I built so now I want to use my Sensebender GW for this instead. On the GW I have allso 4 buttons and 4 relays so my question to @Anticimex is:

Witch pins on the MYSX connector do you recommend for the buttons and relays?

I was thinkin:
Buttons:
MYSX_D1_DFM
MYSX_D2_DTM
MYSX_D3_INT
MYSX_D4_INT
Relays:
MYSX_D5_PWM
MYSX_D6_PWM
MYSX_D9_A3
MYSX_D10_A4

Can I assign the pins like this in my sketch:

const int relayPin[] = {MYSX_D5_PWM, MYSX_D6_PWM, MYSX_D9_A3, MYSX_D10_A4};       //  switch around pins to your desire
const int buttonPin[] = {MYSX_D1_DFM, MYSX_D2_DTM, MYSX_D3_INT, MYSX_D4_INT};   //  switch around pins to your desire

Here is the complete sketch, please comment if something can be improved:

 *
 * DESCRIPTION
 * The EthernetGateway sends data received from sensors to the ethernet link.
 * The gateway also accepts input on ethernet interface, which is then sent out to the radio network.
 *
 * The GW code is designed for Arduino 328p / 16MHz.  ATmega168 does not have enough memory to run this program.
 *
 * LED purposes:
 * - To use the feature, uncomment MY_DEFAULT_xxx_LED_PIN in the sketch below
 * - RX (green) - blink fast on radio message recieved. In inclusion mode will blink fast only on presentation recieved
 * - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
 * - ERR (red) - fast blink on error during transmission error or recieve crc error
 *
 * See http://www.mysensors.org/build/ethernet_gateway for wiring instructions.

@korttoma you can use any pin that can provide the type of functionality you need (for example, don't expect that using an analog pin for digital data to work). Just keep in mind that by using certain pins, you might have to give up features you might like to use later on (like in this case you take the dfm and dtm pins, so you have "taken" the UART pins if you ever plan to use that for your board).
As for the definitions, I am not sure. @tbowmo made the mappings for that port. I believe it looks good.

[tbowmo]

@korttoma
Like @anticimex said, you will loose possibility of using the serial port if you use the dtm/dfm lines.

But besides that, you are free to use all the ports as digital input/output, except the i2c pins as we have an i2c eeprom that is connected to the same pins.

[korttoma]

Thanks @Anticimex and @tbowmo I have the GW up and running with one external sensor now. I just need to connect the buttons and relays to test those.

I'm not sure if I will ever need the UART pins but I will make the hardware so that I can easily change the pins used for buttons and relays.

btw, what is the use cases for UART pins?

[Anticimex]

@korttoma if you have peripherals on your daughter board that communicate using a serial protocol it makes sense to leverage any hw UART capable blocks on the main board. The MYSX standard just indicate that if the main board has such capability, the interface is available on those two pins. You can of course bit bang it on any digital io (depending on core clock) if you need several interfaces.

[Anticimex]

@korttoma that said, note that the dtm and dfm pins also serves as general digital io, so you can use them like any Dx pin.

[korttoma]

Button and relay pins I assigned seem to work correctly but now I managed to release some magic smoke from the Sensebender GW board :( shorted something by mistake and at least FB1 is tost. Can I just shor FB1 to see if the board is stil alive or do I have to replace FB1? Seems like nothing else was damaged (at least I hope so) since it was GND and Vraw that was shorted.

Edit: Just confirmed that it is only FB1 that was destroyed the rest seems to work :D just cant power it from the USB anymore. Hope I can stil write to it.

FB1 is just a filter to suppress spurious RF (if any) on the gnd wire exiting the board. So it can be shorted. The gateway should function fine without it.

Hi All,
I have purchased a SenseBender Gateway, tested the MySensors MQTT code etc on it and thats all good.
Now I want to experiment with my own code on it. I notice that in the example code there are some references to the onboard LEDs, such as;

static uint8_t leds[] = {LED_BLUE, LED_RED, LED_GREEN, LED_YELLOW, LED_ORANGE};

which is great, I will use those to manage the LEDs in my sketch.
What I'd like to know is where are LED_BLUE, LED_RED etc actually defined? What file? The reason I ask is that I also want to know which pin is connected to the RFM69 RESET pin. On the schematic for the SenseBender it is labelled RESET_RFM on the SAMD21 chip, and is physical chip pin 23 and also PB10. I don't know how to use that in my sketch, so if I had a macro like there is for the LEDs then I could just call that.
I'm assuming that if I find where LED_BLUE is defined I may find info about the other pins I also want to use :)

Thanks,
Paul
