@yveaux thanks for that piece of information!!
This was driving me crazy. I know this is an old thread, but this is still a problem today.
I think this should be added to the documentation and probably add one example with this setup properly working.
@mfalkvidd said in NRF51-52 PA not support ???:
the return value of send() indicates whether the sending node received an acknowledgement from the next node. If the next node (the gateway unless you have repeaters) received the message and send() still returns false, it usually means that the acknowledgement was lost.
Maybe the PA makes it possible for the sending node to reach the gateway, but the gateway is unable to reach the sending node?
The network is simple, this node is nrf52 with an amplifier and a gateway with the nrf24 radio module with an amplifier. It would be strange if a gateway with an amplifier could not deliver ACK. Two moments, or I did a very bad control of the amplifier on the node nRF52 or in the radio driver itself, something is not working well, and may need some delay settings. If i send messages with an ECHO (soft ack) request, this works fine over very long distances. Hw ack does not work properly.
