My NRF24L01 is powered supply by an external source.

All the above steps were OK, I did 3 times from the start!

Are you sure it is the correct port name? 😀

Hi gohan, unfortunately I have, I'm doing this procedure:

https://forum.mysensors.org/topic/2437/step-by-step-procedure-to-connect-the-nrf24l01-to-the-gpio-pins-and-use-the-raspberry-as-a-serial-gateway-mysensors-1-x/2

I had already change this number, and this issue continues. This virtual USB port was created here:

sudo ln -s /dev/ttyMySensorsGateway /dev/ttyUSB20

[gohan]

I can't help much, I always used ethernet GW or MQTT as to me are much better
