iOS App crashes on "start" press for DFU

[alexheslop]

I'm connecting to an nRF52832 chip using the iOS nRF Connect app, and trying to trigger a DFU. When I load the file and press start to kick off the transfer, the application crashes and resets. This is with an iPhone X on iOS 16.7.4.

Same with nRF5340. Worked great in last release

@reddwarfSiddis So for the n5340, I believe it's a crash we tried to fix, but didn't fix, and I did not merge it properly for the newest release. But we have a fix for it. I'm trying to add some more fixes related to iPad use of the app and hopefully I can send it to Apple for release this week. Sorry for the inconvenience.

Ok, the nRF5340 should be fixed in 2.7.5, which is in the App Store already. @alexheslop - what SDK version is the DFU? I presume this is 'NordicDFU' and not the newer Zephyr / McuMgr, correct?

Could you paste here the manifest.json file from the ZIP which you're trying to upload?

Let me try this out tomorrow. I think I see a possible issue when parsing the manifest that I might need to fix. Thanks.

[alexheslop]

Thanks @dinesharjani!

[dinesharjani]

@alexheslop something weird is going on during Unzip. It's not doing what I expect. I imagine when you select the file, the Preview is not populated?

[alexheslop]

[alexheslop]

It seems to preview it okay @dinesharjani, but it fails instantly on sending the request

[dinesharjani]

Okay. But it doesn't crash.
