If you are not getting the data you thought you would get, Are you sure you update the memory content before you actually try to send the data? If you use eventready to capture the timestamp I think you might be to late for the content to be updated on time for it to be part of the on air packet.

Hello，

I have printed the NRF_RADIO->CRCSTATUS, and it always be '1' when reception finished.

The nRF52832 Product Specification v1.4 says "the PACKETPTR is the packet address to be used for the next transmission or reception", and actually I have followed this instrction, so what do you mean to update the packet pointer close to tx?

Thanks.

Hi,

Are you checking the CRC? Could you be updating the packet pointer to close to tx?
