Hi, thanks you so much for answer. I continue to search and I think I find what is wrong.. . .. It's because I use pin pitch female [image: 1652640171597-6d6ade87-7585-4789-97e1-2ed0689a769e-image.png] And the connection is very bad.. Sometime it's work, sometime don't.. . I sold it, and I correctly use 3 NRF now... I continue to compare but now I have a comparaison point... :) I continue to search but you're right, the parent ID is not setup same way on different sketch. I try it next week.

Thanks to all. It's very strange. I try to test NFR with Uno and PCB regulator (3V3 + capacitor) , It's work with old NRF but when I switch old NRF to Ebyte, it's not working... But I test Ebyte antenna to my gateway and it's working, so it's not broken
