Reset after DFU Abort

[luktym]

Hi,

I am writing a DFU Application on NRF52 and Android (based on NRF Toolbox). I would like to give user an ability to abort upgrade, however when i send abort from android to nrf, nrf aborts upgrade but after that stays in bootloader (waiting for another DFU package). I Would need NRF to restart and load main application. Is it possible?

Hi,

Which SDK version are you using? The bootloader in SDK 15 should always reset after a Abort request. The bootloader should start the application upon reset, provided that a valid application is present.

Thanks for answer. I use SDK 14.1, i tried multiple times but nrf does not reset after abort.

Yes, then that is expected. The abort command did not exist in SDK 14.1.0, but was introduced in SDK 15.0.0. The easiest way to get this is probably to migrate to the bootloader from SDK 15.

I preffer to stay on 14.1 because i've got fully tested app on this sdk. Maybe there is a way to send reset or load app command to dfu app separately from abort?
