nrf52832 and pa lna witn esb protocol

[ajaksi]

I am trying to implement PA + LNA to nrf_esb.c, if I set in PA constantly ON, receiver gets good signal but sender cannot get ACK, if I set LNA constantly ON, receiver signal strength is bad, so I should add PA off + LNA on to nrf_esb.c after tansmit, before ack is received, but where (in code), how I know transmission is ready and we wait for ACK (LNA ON). Also before automatic retransmission PA should put ON, LNA OFF.

Unfortunately the ESB library don't have any direct support for PA/LNA, however you may find this thread useful:
