How to change the DFU UUID in Android-DFU-Library

[lolifrog]

Hi All,

    I have developed a Bluetooth application with nrf52840, which can be upgraded through our  own  APP  (implementation 'no.nordicemi. Android: DFU: 1.10.3'). However, anyone can upgrade

through nRF Connect with dfu button.

    My question is how to design a program that can only be upgraded by internal personnel, and others can't upgrade the application through nRF Connect?

    Now my solution is to modify the UUID of DFU on nrf52840，but I don't know where to modify the UUID of DFU in android app. I don't know whether this scheme is right.

Best regards,

Steven

Hi Steven,

I must admit I am no Android developer but it seems you will find the relevant parts of the library code by reaching for getService or UUID in the repository.
