DFU abort() midway zip upload never exits DFU mode

DFU Bootloader version:

• SDK version: 29
• Bonding used: yes
• Library version: 1.10.3

Device information:

• Device: Pixel 3
• OS: Android 10

Your question When I abort (at 16% as shown on the logs below), the device stays in DFU mode forever (I’ve left it overnight and it never leaves it). If I remove the batteries, still doesnt reboot into the old app. The only way to make it work again is to use the NRFConnect app and force a DFU.zip to make it exit.

And according to the documentation:

/** * Aborts the upload. The service does not need to be paused before. * After sending {link #BROADCAST_ACTION} with extra {link #EXTRA_ACTION} set to this value * the DFU bootloader will restore the old application (if there was already an application). * Be aware, that uploading the Soft Device will erase the application in order to make space * in the memory. In case there is no application, or the application has been removed, the * DFU bootloader will be started and user may try to send the application again. * The bootloader may advertise with the address incremented by 1 to prevent caching services. */ public static final int ACTION_ABORT = 2;

the DFU bootloader will restore the old application I was expecting this to happen. Am I not doing something correctly?

Thanks in advance

With single back you can’t restore the original fw. It’ll stay in the bootloader mode, as there’s no app available.

Yes I think it can be good to add the command, if it is developed in the SDK you might as well add it to the library.
