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
