Troubleshooting

I haven't tried this yet, but "mtiutiu" replied to the issue on GitHub, and suggested a script that would basically automatically add the __attribute__ ((weak)) during the compile. Sounds like a promising temporary workaround :)

@babajun no, it is because the esp8266 has no sleep mode that is useful. Esp8266 requires a full restart after sleeping. Use wait() instead.

Asking the controller at startup: issue a request, see https://www.mysensors.org/download/sensor_api_20#requesting-data, imo you should as for V_STATUS. Then your controller should respond, the response is handled by the receive()-function (=no action needed), but to get this to work, your node should not sleep (you sketch seems to be incomplete wrt. that). But you should first switch off everyhing to have it in a defined state and avoid loading values from the EEPROM. Wrt. to regular status info: If that's necessary, you should try to use a so called "non blocking loop", use g**gle or similar for that. Imo, it's not necessary to update the value as it doesn't change. Better use the heartbeat funcionality instead (dependend on your controller).

I am use switching DC-DC the same as you to get 5V from 12V and LDO XC6206 to power NRF24 module - all work good. [image: alarm_2.jpg]

Hi Eduard, I know the topic is about 2 years old now. But since I am about to start a project and I plan to buy a decagon leaf wetness sensor I really wondered if you managed to get it running on the Arduino. Thank you very much Best regards Mathias

@zboblamont said in 1.2 MPa pressure transducer: In industry we used to use them atop valves to not only permit servicing but an air pocket acted as a buffer. Thanks, i'll try the pipe / buffer method and see if that helps. Will use a PVC pipe to rule out any EMC reaching the sensor.

@lood29 Thanks for you reply ! I think too it's the SPI implementation on the BPI. I will add a Arduino nano on serial GPIO pin. Or buy a real raspberry pi.

You will get multiple messages, if the message arrives correctly but the hardware ACK doesn't. Do you have a repeater in between the sender and gateway? It could be that the repeater does receive the initial message (and the sensor gets a hardware ACK), but that never reaches the gateway because of a transmission error between the repeater and the gateway.

@Nca78 I'm also guessing this isn't the vacuum cleaner troubleshooting forum (unless I misidentified the the Neato D6)? :laughing:

The wait(100) worked thanks. I`m using an 10uF so far.

Dropping this here for future searchers: I'm seeing this with the platformio framework-arduinoststm32-maple framework as well. The problem appears to be multiple definitions of premain() and main(). I suspect one should be marked with the "weak" attribute to allow the other to override as needed. Though the question is which one? (NOTE: I'm not sure if the Arduino compiler/linker know/care about "weak") I'm new to the platformio so am having trouble sorting out what is coming from where in order to know who to ask about this. I'm suspecting its the stm32duino folks. Take a look at this forum comment where I've shown the syntax for the "weak" attribute if interested in going this route.

Have added log + strace output to the issue on Github as well: https://github.com/mysensors/MySensors/issues/1342 stat64("/etc/localtime", {st_mode=S_IFREG|0644, st_size=3503, ...}) = 0 write(4, "Sep 05 09:03:46 DEBUG GWT:RFC:C="..., 51) = 51 write(2, "Sep 05 09:03:46 \33[36mDEBUG\33[0m ", 31Sep 05 09:03:46 DEBUG ) = 31 write(2, "GWT:RFC:C=0,MSG=0;255;3;0;2;\n", 29GWT:RFC:C=0,MSG=0;255;3;0;2; ) = 29 --- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=NULL} --- +++ killed by SIGSEGV +++ Segmentation fault

First of all, I think some of your code is wrong: h3 = dht3.readHumidity(); // Sensor readings may also be up to 2 seconds 'old' (its a very slow sensor) t3 = dht3.readTemperature(); // Read temperature as Celsius (the default) // Read temperature as Fahrenheit (isFahrenheit = true) f3 = dht3.readTemperature(true); if (isnan(h) || isnan(t) || isnan(f)) { Serial.println(F("Failed to read from DHT sensor 3!")); return; } It needs to be changed to if(isnan(h3) || isnan(t3) || isnan(f3)) to detect if the third sensor returns NAN. Secondly, have you checked your wiring and the code is exactly the same as the first sensor and the second? Third, is this situation due to insufficient power supply? I think you can check the circuit information of the DHT22.

Ok. Sorry. Working --my-transport=rf24 --my-gateway=ethernet --my-port=5003 --my-gateway=ethernet

@taserface987 no worries, glad I could help!
