Hi all,
I have been using an MQTT gateway on a RaspberryPi3 for a couple of years, but would like to migrate Openhab to a x64 mini PC.
I would like to know if it is possible to implement a gateway on Linux using a USB stick with an NRF24L01 on board like these:

Thanks and regards

In my case, the most important things for a successful communication are:

1. A good 3.3V power source (I used an adapter for nrf24l01 + with AMS1117);
2. A 10uF capacitor (very important). In my case a 4.7uF capacitor was sufficient to pilot the nrf24l01 + PA + LNA at RF24_PA_LOW level.
