Both on android and IOS stops DFU process if device reports busy using Nordic DFU_MCUMGR lib

[Tommy F Kristensen]

I have been experience that the if the device under a DFU process reports the error BUSY, because the external flash on the device is used for fileaccess the DFU process from the app fails and stops.

I have to resytart the whole process, it seems that the lib does not handle that it can get a busy back and then retry sending the package again.

Im using nRF54L15 and SDK3.0.2 and latest lib for uploading DFU from app

Link to lib used

https://github.com/NordicSemiconductor/Android-nRF-Connect-Device-Manager

I haven tried to wrtie a handler to handle the BUSY, but it need to restart the whole process each time and cannot resume if it get one BUSY.

I the busy from flashin in the verification part Error 257 is reported,, and the device does not seems to be recoverable from that state only with a reset

Hi, yes, we will handle this status in the library. We will soon switch to nRF Connect Device Manager project.

Hi Tommy. Dinesh here, I maintain the iOS DFU Library (McuMgr).

Are you guys able to pull from main branch and test a possible fix for this? Or do you need a release? This is so I can push a possible fix, so you guys can test whether it works for you or not, and provide some feedback without the need for a release without knowing for sure if it works out.

Thanks.

Bit of follow-up - there's a possible fix in the main branch. Let me know when you've tested it.
