[SOLVED] My node fails to send

[David Muller]

Hello everyone, I'm new here.
I built my first project with the MySensors framework, and I don't know why I have communication issues.
Here's the hardware configuration :

• Sensor node : arduino nano with a DS18B20 and a NRF24L01+ (with 47µF cap on Vcc Gnd)
• Gateway : ESP8266 and NRF24L01+ (send MQTT message via wifi)
• Message decoder : Raspberry Pi 3B with node red

I can see on my Raspberry incomming MQTT messages when I subscribe to the topic, but the payload is always empty !
When I check the nodes console log, I see always the same error at the same moment.
Here is what I get in the console (sensor node)

16 MCO:BGN:INIT NODE,CP=RNNNA---,VER=2.3.0
25 TSM:INIT
26 TSF:WUR:MS=0
33 TSM:INIT:TSP OK

20100 TSM:FAIL:RE-INIT
20102 TSM:INIT
20109 TSM:INIT:TSP OK
20111 TSM:FPAR

Here is the failed line using the log parser : "Transition to Failure state, consecutive failure counter is 1"

So I think this is why I never get a payload in my MQTT messages, the sensor node does'nt even send the sensor data, but I don't know why !

Have someone ever had the same situation ?

Thanks for your help.

@david-muller hi and welcome to the forum!
Your sensor node should either have a fixed node ID, or your controller should hand one out on request by the node.
As you're using node-red the easiest solution is to hardcore the node ID in the sensor node :

#define MY_NODE_ID 1

and place it before #include <MySensors.h>

@David-Muller

If you don't want to hardcode node ID's then there is the option of using node-red-contrib-mysensors, and the MysController node within that package, as it can hand out node ids for you.

Beautiful, I added the define and it works very good now !
Big thanks to you !!!
