Detect ACK/NAK of polls

[ksathara]

Hi,
Is there a way or callback in an SED to detect ack/nak of polls from it's parent?

Cheers,

@ksathara, the radio API otPlatRadioTxDone() is a callback from the radio reporting the status of a frame TX request (whether an ACK was received or an ACK timeout happened). This is then processed by SubMac and Mac and may go through all the subsequent layers.

The DataPollSender module tracks and handles poll TX (on an SED) to the parent and performs a variety of functions, including retries of polls on TX failure. See DataPollSender::HandlePollSent().
