One approach would be to create a separate task on the ESP32 that takes care of testing this sensor, than the gateway is not affected.

@BearWithBeard Thanks. That sounds like what I was thinking. Makes it clearer though.

mfalkvidd gave you a great link, but if you ever need to see any possible choices, you can run ./configure --help and it will show you. The extra flags section is one thing (of many) that it says. Actually, this is very timely for me, as I'm trying to troubleshoot my own radio issues, so I'll use those extra two flags that you mentioned and see what they say. Thank you!

@Njwyborn sorry, I don't know. If the stack is called recursively, something is seriously wrong and behavior is undefined I guess.

Also posting the wiring helps others to help you. Fitzing is easy for this task

@mfalkvidd Thank you!

@Ispandy, let resume some things because I'm lost You copied the sketch code from node 3 (= correctly running node with cardscans and remote control from openhab) to node 50 and you adapted the node id. This same sketch on node 50 is running correctly with cardscans but not with openhab? Correct? If above is correct: somewhere your openhab configuration for this node 50 is not correct. You say that node 50 is never receiving the openhab command, so there is a problem with your openhab configuration for node 50.

I am using the TMRh20 libraries (not the MySensors library) and have the same problem. I'm pretty sure that there are interrupts that are not being reset. One of my other symptoms is that when I try to load or reload a program, the program doesn't start. I have a program program that I run that works most of the time and gets me to the point of being able to reprogram the Arduino //cli(); // disable all interrupts WDTCSR = B00011000; // set watchdog timer into configuration mode WDTCSR = 0; // turn off watchdog time interrupt. //sei(); // allow interupts I use this technique to load the program: write program use Tool-->port and set the port on the device, press and hold reset button <ctl>+u or click on upload icon when compiling gas gauge is almost complete, release the reset button. You may have to do 3)-5) several times. You could put: Serial.begin(9600); Serial.println("WDT reset"); at the end of the program to know that the device got reset. I hope this helps you. I, too, would like something a little more controllable. OSD

@pw44 MY_DEBUG is usually enough. https://www.mysensors.org/build/debug#enabling-debug-and-monitoring-the-logs and https://forum.mysensors.org/topic/666/read-this-first-it-could-save-you-a-lot-of-time/ can be useful.

Upgrading to 2.3.2 has helped somewhat

@mfalkvidd may this problem be related with eeprom stored vars? i will clear the eeproms and flash gatewayand nodes again.

@bcdaus from what I understand, ! means failed while ? means unknown. Unknown is used when the radio hardware does not support ack at all (so there is no way to know whether the message was received by the next node) https://www.mysensors.org/apidocs-beta/group__MyTransportgrp.html has some documentation.

Hi @mariuszjozala , Thank you for reporting back. Glad that it works now! In my eyes, the good documentation (and availability of LTS options) is one of the really big plus points of the NanoPi/FriendlyARM products. I did save a local copy of their wiki, just in case it ever disappeared, because these references are really helpful. Best regards pragtich

@jlb said in Radio stops working: How to make the node detect this radio problem ? I don't think there is a function to do this, but maybe someone else can help with that. How do I get my sketch to do a cold restart of the radio ? It would be good to see how you wired this all up - a hand drawn sketch or fritzing would do. I suspect that by modifying the way power is applied may need arjusting and come capacitors may need adding - You can reboot by using a hardware watchdog circuit (web search for it).

Question. Would using the "ClearEepromConfig" sketch, do anything nasty to the sencebender gateway eeprom?

@Yveaux Yes, that is what the sencebender gateway was for, so I could start with an easily swappable item, and the core of the network, however you might remember that I am having issues with sencebender gateway.. with no solution in sight. link text

@TheoL Thanks for responding and sorry for my late reply. I finally got an Arduino Nano working as a gateway with RFM69. It required new/different logic converters as the ones I had apparently were not working correctly. I can give the RFM69 3.3V power from the Nano, but as the Nano has 5V logic and the RFM69 cannot handle 5V logic as input (NSS, SCK, MOSI) , the logic converters are needed to protect the RFM69 module as also stated in the MySensors radio guide. I must say that using NRF24 was much easier than using RFM69, but I will stick with RFM69 (433 MHz) for range reasons.

This solved my issue!! Thank you!!

@pw44 downgraded ESP from 3.0.1 to 2.7.4 and issue is gone.
