how to set nRF24 PTX with ack payload

[Chaw]

Hi，Nordic now, nRF52 as PRX, nRX24 as PTX.

App process

1. PTX send data via ESB, PRX can receive

   But nRF24 can not receive event HAL_NRF_TX_DS, why?

2. Then nRF52 send payload, but nRF24 can not receive

If nRF52 as PTX, nRF24 as PRX, it's OK.

Could you tell me how to set nRF24?

Thanks.

Hi Chaw,

We are suspecting it was the bug with the inverted NO_ACK bit on the nRF5 ESB library.

Could you try this workaround file to replace the original one and let me know if it fixed. Two modification been made on line 482 and 694.

nrf_esb_NOACK_Fix.c

[update] Here is an example of using nRF24LU1 as PTX and nRF52 as PRX with ACK payload.

Hi, it doesn't work. same to without modification.

my app is this:

1. nRF24 as PTX, nRF52 as PRX

2. nRF24 send data to nRF52, it work well.

3. nRF24 change to PRX mode, nRF52 send data to nRF24 (via nrf_esb_write_payload)

this time, nRF52 nrf_esb_write_payload return success, can not receive TX Successful or TX Failed event.

nRF24 can not receive data from nRF52.
