Ok, now I load a sketch into an arduino nanowith nrf24l01+ and this is all I got:

Stuck again.

With mqtt gateway I got further ahead:

I had to use spidev0.0 and not spidev1.0:

FYI i configure like this:

Hello! I followed instructions by SdeWeb on my Orange Pi Lite with Armbian, and gateway is working fine, I can see debug messages from other node. But when I try to add a serial port in node-red I can't find the gateway one. Can you help me?
