Help with NRF24L01+PA+LNA

Hello,

I am trying to get a pair of NRF24 to send and receive data. I am using Robin2 examples with no modifications as well as a 10uF capacitor as recommended which I do not think I need since they are on breakouts but its there anyways. I have also tried with no capacitor added.

The NRF24 module has been powered from the Arduino nano's 5v pin as well as externally powered with a buck converter at anywhere between 4v-5v with no differences. I have also tried 2 double A batteries to no avail. The antennas are currently about 15 feet apart and I have tested 3 modules and non seem to work as a transmitter. All 3 have checked ok with Robin's module checker as well.

I have attached the nrf24 module check outputs as well as a photo of the wiring for 1 nrf module as they are both wired the same currently. Please let me know if there is anything else I can provide.

The connection test results seem to indicate that the modules are wired up correctly. The modules require 3.3v power so there's a chance that they may have been damaged when you applied 4-5v to them.

Whilst Robin's tutorials are an excellent starting point to the world of nRF24L01 modules, they are based around the basic module without the LNA & PA RF sections. As you are using the higher power versions, then, whilst testing on the bench, I would suggest that you reduce the RF power of the modules.

Try inserting the line:

radio.setPALevel(RF24_PA_MIN);

at the end of the setup() section.

Please include the text of the output in your Post so we don't have to download stuff.

Also please post the code that YOU have uploaded to each of your Arduinos and a sample of the out put from each of the programs.

Do you have a pair of low-power nRF24s for testing with? - the code will be identical.

Hello,

Thanks for the replies...sorry for the slow answers as I am on call this week and our production database crashed Monday night....fun times.

I do not have low power nrf24s but I will purchase some for testing and will upload the requested files as code blocks for easier review!
