Detailed Description

Struct to hold the Telephone Bearer Service client callbacks.

These can be registered for usage with bt_tbs_client_register_cb().

Field Documentation

bearer_provider_name

void(* bt_ccp_call_control_client_cb::bearer_provider_name) (struct bt_ccp_call_control_client_bearer *bearer, int err, const char *name, void *user_data)

Callback function for bt_ccp_call_control_client_read_bearer_provider_name().

This callback is called once the read bearer provider name procedure is completed.

Parameters

bearer	Call Control Client bearer pointer.
err	Error value. 0 on success, GATT error on positive value or errno on negative value.
name	The bearer provider name. NULL if err is not 0. Value must be copied if used after return.
user_data	User data stored in the callback struct. Will always be NULL if CONFIG_BT_CCP_CALL_CONTROL_CLIENT_CB_USER_DATA is not enabled.

bearer_tech

void(* bt_ccp_call_control_client_cb::bearer_tech) (struct bt_ccp_call_control_client_bearer *bearer, int err, enum bt_bearer_tech tech, void *user_data)

Callback function for bt_ccp_call_control_client_read_bearer_tech().

This callback is called once the read bearer technology procedure is completed.

Parameters

bearer	Call Control Client bearer pointer.
err	Error value. 0 on success, GATT error on positive value or errno on negative value.
tech	The technology of the bearer. The value may be outside the values of the enum.
user_data	User data stored in the callback struct. Will always be NULL if CONFIG_BT_CCP_CALL_CONTROL_CLIENT_CB_USER_DATA is not enabled.

bearer_uci

void(* bt_ccp_call_control_client_cb::bearer_uci) (struct bt_ccp_call_control_client_bearer *bearer, int err, const char *uci, void *user_data)

Callback function for bt_ccp_call_control_client_read_bearer_uci().

This callback is called once the read bearer UCI procedure is completed.

Parameters

bearer	Call Control Client bearer pointer.
err	Error value. 0 on success, GATT error on positive value or errno on negative value.
uci	The UCI of the bearer. NULL if err is not 0.
user_data	User data stored in the callback struct. Will always be NULL if CONFIG_BT_CCP_CALL_CONTROL_CLIENT_CB_USER_DATA is not enabled.

bearer_uri_schemes

void(* bt_ccp_call_control_client_cb::bearer_uri_schemes) (struct bt_ccp_call_control_client_bearer *bearer, int err, const char *uri_schemes, void *user_data)

Callback function for bt_ccp_call_control_client_read_bearer_uri_schemes().

This callback is called once the read bearer URI schemes supported list procedure is completed.

Parameters

bearer	Call Control Client bearer pointer.
err	Error value. 0 on success, GATT error on positive value or errno on negative value.
uri_schemes	The URI schemes supported list of the bearer if err is 0. Value must be copied if used after return.
user_data	User data stored in the callback struct. Will always be NULL if CONFIG_BT_CCP_CALL_CONTROL_CLIENT_CB_USER_DATA is not enabled.

discover

void(* bt_ccp_call_control_client_cb::discover) (struct bt_ccp_call_control_client *client, int err, struct bt_ccp_call_control_client_bearers *bearers, void *user_data)

Callback function for bt_ccp_call_control_client_discover().

This callback is called once the discovery procedure is completed.

Parameters

client	Call Control Client pointer.
err	Error value. 0 on success, GATT error on positive value or errno on negative value.
bearers	The bearers found. Value must be copied if used after return.
user_data	User data stored in the callback struct. Will always be NULL if CONFIG_BT_CCP_CALL_CONTROL_CLIENT_CB_USER_DATA is not enabled.

user_data

void* bt_ccp_call_control_client_cb::user_data

User data that will be supplied to all callbacks.
