Hey ...
So ... i'm trying to make a radio control receiver & transmitter ... I have no problem using NRF24L01 but when I try to use the NRF24l01 + PA + LNA I don't get any results ... they kinda are the same thing ... right ??
I've been using 2 NRF24l01 modules and now I'm trying to use 2 NRF24l01+ modules ... but tey don't work ... is there any difference between these two ??
Wireless problems can be very difficult to debug so get the wireless part working on its own before you start adding any other features.
The examples are as simple as I could make them and they have worked for other Forum members. If you get stuck it will be easier to help with code that I am familiar with. Start by getting the first example to work
There is also a connection test program to check that the Arduino can talk to the nRF24 it is connected to.
A common problem with nRF24 modules is insufficient 3.3v current from the Arduino 3.3v pin. The high-power nRF24s (with the external antenna) will definitely need an external power supply. At least for testing try powering the nRF24 with a pair of AA alkaline cells (3v) with the battery GND connected to the Arduino GND.
Also, it seems to be important not to have a high-power module too close to the other module - try having them 3 metres apart.

A good place to start when using any of the NRF24 range is to use the adaptor module.
It avoids many problems.
