Hi, I'm using a TCP gateway without any problems. Just place a TCP node in input instead of your MQTT node, I used this tutrial

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

Hi, I finally solved the issue, the node takes about 0.02mA in sleep mode, the problem was located on the nrf24L01+, I had a 5 of them, and two nrf did the same problem (to much current in sleep mode).
So I will keep the "hungry" NRF for sector supply nodes.

Bye
