I tried both using my laptop's usb ports. Then I used a battery on the sensor node.

Note: I didn't power the nrf with the battery, just the arduino.

I just got 4 nrf24l01+ modules with the external antennas, but I'm not able to make them work.

I'm using arduino nanos and MySensors to create a gateway and a sensor.

The funny thing is that when I put a antenna nrf as the gateway and a pcb nrf as sensor, they work just fine, but the other way doesn't.

I also tried two nrfs as gateway and sensor, but the behavior does not look good.

What could it be? Wifi router interference? Channel? Baud rate? Data rate?
