NRF24L01+ no stable connection

Hello there,

For a project I need to make a stable connection betweet 2 NRF24L01+'s.
I have gained a connection between the too. But its everything but stable.

Serial Monitor output (We're sending "Hello There!")

Code:
HERE

Both the NRF24L01+ are soldered on to a PCB with the arduino.
I've connected the Arduino with the NRF24L01+ followed by the RF24 Library.

Does anyone know what the problem is?

Thank you,
Terick

What range, what capacitor have you got on the power of the radio module and are you going through walls etc?

Also have you tried changing channels? (At both ends)

Hello ChilliTronix,
Thank you for you reaction :slight_smile:

We do not yet have any capacitor between the power and the radio module.
Would this really make that big of a difference?

It is not going through anything, the range is like 1 meter distance.
How could we change channels?

You should have a 10uF or similar electrolytic capacitor across the +Ve and ground of the NRF24L01 module, where you plug its wires into a breadboard for example. Try that first.

Electrolytic capacitors are polarised so remember to get them the right way around.

Are you powering both NRF24L01+ from the Arduino? If so, that's almost certainly the problem.
I've just been playing around with one NRF24L01+ and I had to connect it to a separate supply to get it to work. With two NRF24L01+, you'll definitely need a separate power supply.
Also, the NRF24L01+ runs at 115200 baud which is quite fast and you may have to be careful how you handle the I/O between them so that you don't lose any characters due to an overrun buffer.
