Singing 2.2.0

Anticimex

@alexsh1 looks like a textbook example where sender and receiver disagree on what hmac key to use.

alexsh1

@anticimex Interesting. I am using the same HMAC key on both Sensebender GW and atmega328p.

No problem if I swap the gateway for Mega.

alexsh1

@anticimex GW has got a lot of these:

!SGN:NCE:GEN

Anticimex

@alexsh1 that indicate nonce generation fails. If you use soft signing it means the backend is not initialized.
If it is not, it is indicating checksum failed. This should be visible in the early init messages.
If you use atsha, it could indicate a dodgy device communication.

alexsh1

@anticimex Sensebender GW has got ATSHA204
A few of my nodes do have ATSHA204 as well
And a few others soft signing

All of them fail after clearing eeprom and new personalisation with the same HMAC

I understand the problem is the Sensebender
Could it be a timing issue on Sensebender GW (SAMD21)?

Anticimex

@alexsh1 if it is, it is new to me. SenseBender gw has been tested with signing. Perhaps @tbowmo might know if something changed in processor frequency on 2.2 that might affect timings in the atsha driver.

@anticimex

I had to comment out this line

#define MY_SIGNING_ATSHA204_PIN   17

For SAMD21 it is connected to 20 (PA11) -> this corresponds to D0 arduino

However, the node still gives me a pain:

All other nodes are working fine with singing so the problem was incorrect reference to atsha204's pin on the GW. I'll debug the node above tomorrow

Anticimex

Alright. That is at least some progress. Just from the latest log I don't see anything going terribly wrong at the node side. But it perhaps hangs at that point? Could be a stack issue.

alexsh1

@anticimex It is working now. It was one of those late night issues. In the morning it started working like a charm! (I bet it won't be able to replicate it). Thank you for your help.

Also a good lesson for me. A working sketch for an AVR may or may not work for ARM. Extra attention required for defining pins etc.

On a different note FYI, I was struggling to clear EEPROM on my Sensebender GW.
See this https://forum.mysensors.org/topic/8814/cleareprom-does-not-work-for-sensebender-gw/9

@alexsh1 nice to hear :)
