Field Documentation

struct bt_gatt_ccc_cfg bt_gatt_ccc_managed_user_data::cfg[0]

Configuration for each connection.

void(* bt_gatt_ccc_managed_user_data::cfg_changed) (const struct bt_gatt_attr *attr, uint16_t value)

CCC attribute changed callback.

Parameters

attr	The attribute that's changed value
value	New value

bool(* bt_gatt_ccc_managed_user_data::cfg_match) (struct bt_conn *conn, const struct bt_gatt_attr *attr)

CCC attribute match handler.

Indicate if it is OK to send a notification or indication to the subscriber.

Parameters

conn	The connection that is being checked
attr	The attribute that's being checked

Returns: true if application has approved notification/indication, false if application does not approve.

ssize_t(* bt_gatt_ccc_managed_user_data::cfg_write) (struct bt_conn *conn, const struct bt_gatt_attr *attr, uint16_t value)

CCC attribute write validation callback.

Parameters

conn	The connection that is requesting to write
attr	The attribute that's being written
value	CCC value to write

Returns: Number of bytes to write, or in case of an error BT_GATT_ERR() with a specific error code.

uint16_t bt_gatt_ccc_managed_user_data::value

Highest value of all connected peer's subscriptions.
