Hi, ive had great success progress with the PA LNA amplified variants of these chipsets. Now as part of my project it calls for some units to use the non PA LNA (smaller) modules with the pcb antenna.
Testing them by swapping them straight into my testing circuits that are working fine with the amplified version, these smaller ones will transmit the same yet not recieve even though the circuits are on the same bench.
Every now and then a packet rarely get recieved and reported, but mostly there's failure.
Im using and have tried with both RF24 and RF24Network library example sketches...
Not sure what to try next except ordering some more from a different source...
