nrf52832 SDK 15.2.0 - Is it possible to deny entering bootloader?

[Andrej]

hello everybody,

In my application i want to check if a password is set, to enter bootloader, otherwise don't start the bootloader.

This should work without bonding.

nrf52832 / SDK 15.2.0 / s132 - Is it possible to deny entering bootloader?

Any ideas?

Hi,

Do you mean weather you can require a password before starting the bootloader via the buttonless DFU BLE service? If so, there is no direct support for it, but I do not see any reason why you could not implement it. You could for instance expand the buttonless DFU characteristic so that you write a password to it, and only start the bootloader in DFU mode if the password is correct.

First thanks for the fast reply, that's a possible solution. I thought there would be an easy way doing this.
