So I see ble_app_hrs and others have some nice examples of buttonless reboot into DFU bootloader. But for security reasons, I'd rather the user hold down the reset button (only button on our board, tied to GPIO) for some seconds to go into bootloader mode.
So I have to code to detect that the button has been long pressed, is there a "reboot into bootloader" example that doesn't use the ble_dfu service?
