I am working with the ble_app_buttonless_dfu example and am wondering why the example sends 2 notification messages in response to a command being written to it? This occurs straight out of the box without any modification to the code.
To reproduce, compile the example, load to a dev board which already has SD132 loaded to it, then connect to it with a BLE app such as light blue. Subscribe to the notification service, and write 0x02 to it. You will get back 2 notifications not one.
I am working with PCA 10040 nRF52
Is there a fix for this?
