Hello everyone! Thank you @mfalkvidd for your answer. I finally found the issue... Timing is particularly critical when reading UART and using the internal RC oscillator isn't a good idea... at all. Especially knowing that its frequency varies (quite a lot in my opinion) with temperature: (Page 274 of the ATMEGA328P datasheet available here: https://ww1.microchip.com/downloads/en/DeviceDoc/Atmel-7810-Automotive-Microcontrollers-ATmega328P_Datasheet.pdf) So, I changed the fuses of the ATMEGA328P to use an external 8 MHz crystal oscillator and now everything works perfectly! Regarding the code, I've initialized the "Serial" object with the configuration SERIAL_7E1, it works as expected! Cheers! Encrypt

@skywatch do Fluke meters work unattended in enclosed cabinets or walls, using varistors for power supply 24/7? As I've said I prefer using a better power supplies with built-in over-voltage protection. As for how it is achieved without a varistor you can find plenty information by yourself using google.

I have not had any trouble just buying my radios the normal way on AliExpress. To me normal means buying about 10 or 20 at a time from the cheapest seller I can find with a high number of sales under their belt and a good reputation. I am getting nRF24 though, not sure if situation is different with RFM59W. I think most of the stuff you read in forums about fakes was from years ago. Or maybe I am just lucky.

Besides what Bob (?) mentioned (you seem to be making progress, breadboard unreliability, specifics), I would point out that there have been a number of discussions about ACKs, re-sending, reliability, keeping stats of NACK percentages (as a possible indicator of some problem), etc. over the years. The most recent I can recall was probably this one that I learned about when @BearWithBeard mentioned it here in my evidence based radio testing method (and capacitors) thread. My thread is more about hardware and radio testing, but we get into the subject of software ACKs etc. there in my thread a bit, and also in the linked thread. Is that the sort of stuff you are looking for?

@bjacobse Thank you - I learn something new! I have WDT enabled on one of the RF gateways and still it crashes (ir never sleeps as it is a GW node). I am using the stock bootloader (chinese clone uno) so I wonder if this is the issue. I will try and upload the optiboot to that GW node and see if it helps. I also run a script in mycontroller to reboot the GW node if it is down, but that isn't working as I expected either..... Luckily I have plenty of time at home now, unluckily I have a lot of domestic chores and support a vulnerable person living at another address, so time for mysensors is still limited, at least for now.

@encrypt said in Signing fails due to NACKed messages: I can't enable radio logging easily but I suspect it could be caused by the auto-adjusting RSSI feature... I'm afraid, but without additional debug information it's gonna stay a guessing game. If possible, enable #define MY_DEBUG_VERBOSE_SIGNING #define MY_DEBUG_VERBOSE_RFM69 for additional info. Also, please post the node sketch to interpret the log in the right context.

Thanks for the feedback @zboblamont! I was probably overthinking the whole thing

@tekka I see. Thanks for explaining.
