You can use the Cy_BLE_GATTS_EnableAttribute() and Cy_BLE_GATTS_DisableAttribute() API functions to dynamically enable or disable a GATT service or characteristic as shown in the following:
Enabling an attribute
Use the following code snippet to enable the attribute entry for a service or characteristic logical group in the GATT database registered in the Bluetooth® LE stack:
cy_stc_ble_gatts_db_attr_enable_info_t handle;
cy_en_ble_gatt_err_code_t gattError;
handle.attrHandle = CY_BLE_BLE_THROUGHPUT_SERVICE_HANDLE;
GattErrCode = Cy_BLE_GATTS_EnableAttribute(&handle);
Disabling an attribute
Use the following code snippet to disable an attribute entry for a service or characteristic logical group in the GATT database registered in the Bluetooth® LE stack:
cy_stc_ble_gatts_db_attr_disable_info_t handle;
cy_en_ble_gatt_err_code_t gattError;
handle.attrHandle = CY_BLE_BLE_THROUGHPUT_SERVICE_HANDLE;
GattErrCode = Cy_BLE_GATTS_DisableAttribute(&handle);
