Typedef Documentation

typedef void(* bt_codec_a2dp_callback_t) (bt_media_handle_t *handle, bt_codec_media_event_t event_id)

This defines the A2DP codec callback function prototype.

The user should register a callback function while opening the A2DP codec. Please refer to bt_codec_a2dp_open().

Parameters

[in]	handle	is the media handle of the A2DP codec.
[in]	event_id	is the value defined in bt_msg_type_t. This parameter is given by the driver to notify the user about the data flow behavior.

typedef int32_t(* bt_codec_get_data) (volatile uint16_t *buf, uint32_t len)

A2DP direct access to DSP buffer function type.

typedef int32_t(* bt_codec_get_data_count) (void)

A2DP get data count function type.

typedef void(* bt_codec_hfp_callback_t) (bt_media_handle_t *handle, bt_codec_media_event_t event_id)

This defines the HFP codec callback function prototype.

The user should register a callback function while opening the HFP codec. Please refer to bt_codec_hfp_open().

Parameters

[in]	handle	is the media handle of the HFP codec.
[in]	event_id	is the value defined in bt_msg_type_t. This parameter is given by the driver to notify the user of data flow processing behavior.

typedef void(* bt_codec_hfp_customer_enhancement_function_callback_t) (void *user_data)
