Summary

Declaration

from esp_ieee802154.h:198

esp_err_t esp_ieee802154_transmit(const uint8_t *frame, bool cca);

Arguments

Argument

Description

frame

The pointer to the frame, the frame format: |-----------------------------------------------------------------------| | Len | MHR | MAC Payload | FCS | |-----------------------------------------------------------------------|

cca

Perform CCA before transmission if it's true, otherwise transmit the frame directly.

Return value

- ESP_OK on success. - ESP_ERR_INVALID_ARG on an invalid frame. - ESP_FAIL on failure due to invalid state.

Notes

During transmission, the hardware calculates the FCS, and send it over the air right after the MAC payload, so you just need to prepare the length, mac header and mac payload content.
