Detailed Description#

Indicates that the value of one or several characteristics in the remote GATT server was received.

It is triggered by several commands: sl_bt_gatt_read_characteristic_value, sl_bt_gatt_read_characteristic_value_from_offset, sl_bt_gatt_read_characteristic_value_by_uuid, sl_bt_gatt_read_multiple_characteristic_values; and when the remote GATT server sends indications or notifications after enabling notifications with sl_bt_gatt_set_characteristic_notification. The parameter att_opcode indicates which type of GATT transaction triggered this event. In particular, if the att_opcode type is sl_bt_gatt_handle_value_indication (0x1d), the application needs to confirm the indication with sl_bt_gatt_send_characteristic_confirmation.
