You have the luxury of choosing your own custom service UUID I guess, hence you are able to write to that UUID on the app as well. Finally, one important thing to remember is that a BLE packet needs to be structured properly which can then be serialized and deserialized consistently in both the server and the client end. Refer BLE tutorial and difference between BLE and Bluetooth. 2021 г. Performing a sniffer trace between a Android/iOS device and a nRF device during DFU can also be usefull as you see all the packets that are sent on-air. But the TB2 just doesn't see it. 2.
