Type Definitions¶
-
typedef void (*
esp_hf_client_incoming_data_cb_t
)(const uint8_t *buf, uint32_t len)¶ HFP client incoming data callback function, the callback is useful in case of Voice Over HCI.
- Parameters
buf
: : pointer to incoming data(payload of HCI synchronous data packet), the buffer is allocated inside bluetooth protocol stack and will be released after invoke of the callback is finished.len
: : size(in bytes) in buf
-
typedef uint32_t (*
esp_hf_client_outgoing_data_cb_t
)(uint8_t *buf, uint32_t len)¶ HFP client outgoing data callback function, the callback is useful in case of Voice Over HCI. Once audio connection is set up and the application layer has prepared data to send, the lower layer will call this function to read data and then send. This callback is supposed to be implemented as non-blocking, and if data is not enough, return value 0 is supposed.
- Parameters
buf
: : pointer to incoming data(payload of HCI synchronous data packet), the buffer is allocated inside bluetooth protocol stack and will be released after invoke of the callback is finished.len
: : size(in bytes) in buflength
: of data successfully read
-
typedef void (*
esp_hf_client_cb_t
)(esp_hf_client_cb_event_t event, esp_hf_client_cb_param_t *param)¶ HFP client callback function type.
- Parameters
event
: : Event typeparam
: : Pointer to callback parameter
