@mfalkvidd Ok thanks for your reply

@mfalkvidd Hello mfalkvidd, I am new on this forum but I had followed Mysensors for a long time. I have the same symptoms as Jan meets. we checked double the wiring connection, and change NRF24L01 module . always the same message:
0;255;3;0;9;Starting gateway (RNNGA-, 2.0.0)
0;255;3;0;9;TSM:INIT
0;255;3;0;9;!TSM:RADIO:FAIL
0;255;3;0;9;!TSM:FAILURE
0;255;3;0;9;TSM:PDT

I Have tried two ways ESP8266 + NRF24L01 (gateway ESP8266) and Arduino NANO + NRF24L01 (serial gateway)same error...
For both assemblies, I used the schematics from mysensors site (connecting radio).
I don't know what I missed, do you have any Idea?
Thank you for your help
