Summary

Declaration

from esp_ieee802154.h:546

extern void esp_ieee802154_receive_done(uint8_t *frame, esp_ieee802154_frame_info_t *frame_info);

Arguments

Argument

Description

frame

The point to the received frame, frame format: |-----------------------------------------------------------------------| | Len | MHR | MAC Payload (no FCS) | |-----------------------------------------------------------------------|

frame_info

More information of the received frame, refer to esp_ieee802154_frame_info_t.

Notes

User must call the function `esp_ieee802154_receive_handle_done()` to notify 802.15.4 driver after the received frame is handled. During receiving, the hardware calculates the FCS of the received frame, and may drop it if the FCS doesn't match, only the valid frames will be received and notified by esp_ieee802154_receive_done(). Please note that the FCS field is replaced by RSSI and LQI value of the received frame.
