how to enable an extern PA in gazell mode?

[chenyu]

Hi: I make the gazell ready, and I need an extern PA(RFX2401) for a long distance commuicate. But there is some trouble when enalbe the PA. My function:

Host:
pin_Set(rxen);
in function host_rx_data_ready()
{ pin_Set(txen);
add_packet_tx_fifo(ack);
pin_clear(txen);}

Device:
pin_Set(txen);
add_packet_tx_fifo();
in function device_tx_success()
{pin_clear(txen);
pin_Set(rxen);
fetch_packet_form_rx_fifo(ack);
pin_clear(rxen);}

Is this method can make both data and ack singal pass the PA? thank you?

Firstly, a PA will not improve the range of your receiver, so it should only be enabled when you are transmitting.

Secondly, a return from nrf_gzll_add_packet_to_tx_fifo() does not mean that the packet is sent.

Maybe you can try what is described in Øyvind's answer here?
