Function Documentation

◆ bt_a2dp_connect()

struct bt_a2dp * bt_a2dp_connect ( struct bt_conn * conn )

A2DP Connect.

This function is to be called after the conn parameter is obtained by performing a GAP procedure. The API is to be used to establish A2DP connection between devices.

Parameters

conn	Pointer to bt_conn structure.

Returns: pointer to struct bt_a2dp in case of success or NULL in case of error.

◆ bt_a2dp_register_endpoint()

int bt_a2dp_register_endpoint	(	struct bt_a2dp_endpoint *	endpoint,
		uint8_t	media_type,
		uint8_t	role
	)

Endpoint Registration.

This function is used for registering the stream end points. The user has to take care of allocating the memory, the preset pointer and then pass the required arguments. Also, only one sep can be registered at a time.
