Hi, I create a library with full documentation for this device and I'm going to release a complete web solution.

Bye
@Eme Thanks for letting us know how you solved the problem - helps us all to learn. I've recently upgraded my Raspberry Pi 1b to 4 and just got it working as an ethernet gateway with standard NRF24 radio. I'm curious about a few things as I've been trying to also use a PA LNA radio but without success;
Any reason you have set up your gateway as serial and not ethernet?
What did you mean by "Don't rely on GPIO pins to power it, use a regulator". By regulator did you mean the capacitor, did you use another regulator component - I can't see from your image
Did you change the power setting of you configuration file MyConfig.h -lowering the power to "RF24_PA_LOW'?
