I would like to update a value of a BLE service and therefore send a notification with acknowledgement (using indicate). The server sends the notification to the client. After the notification is successfully received by the client it should send a confirmation message back to the server which acknowledges the successful communication.
Is there already implemented a callback to handle the received acknowledgement so that the server knows that the notification was successfully transmitted to the client? I have not found something in the references. Do you have a API with all callbacks?
