    Hi Aries,

    If APSDE_DataReq fails then APSF_TxNextFrame will attempt the same fragment message up to APSC_MAX_FRAME_RETRIES times, if this is surpassed then AF_DATA_CONFIRM_CMD is returned with a ZMacNoACK status and the APSF_TxObj_t structure memory is freed.

    If you are observing faulty behavior, please demonstrate this with a sniffer log and debugging observations.

    Regards,
    Ryan
