Problems with NRF24L01+PA+LNA

Hi,

I have been using NRF24L01 with success for a while. Bought a pair of NRF24L01+PA+LNA link

They are supposed to have the pinout as these one i used succesfully link

Trying with nrfping-samplecode i can only get pair to communicate if i dont connect ground on nfr??!! :o

this apply to both of nrf:s i have to disconnect ground from them and they can send data

Any ideas?

Likely a power supply issue if it works fine with other modules, the pinouts should be the same.

The easiest way to prove that out is by turning down the PA level. If using the RF24 library:

radio.setPALevel(RF24_PA_MIN);

I manage to get it running. Maybe a loose cable but now it works with ground connected. Always use a 10uF capacitor between +3.3v and GND and i resoldered them both Also decided to try out the for me new RadioHeadlibrary
