Hi,

Upgrading the app to latest version (1.5.2) solved the matter :)

Hi,

I have not had a chance to get new info from the maintainer now, but the pipelining change that was described before should be the only relevant change as far as I can see. You can try to do things on the nRF side as well though, like setting CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU_SPEEDUP=y.

Hello again,

Any new ideas of what might be causing the issue?

I just got to check the Device Manager update on an older mobile device model (iPhone X), when upgraded the app to latest version (v1.4.3) image upload speed was reduced by half again.

Hi Einar,

Thanx for the response.

I'm using iPhone 14 with iOS 17.0.3, updated the Device Manager to 1.4.3 from 1.4.2, but since the release was only a couple of days after the previous version I'm not sure which of the two last versions introduced the issue on my device. When I used version 1.4 the upload rate was definitely higher though.

As for now I haven't tested it with a different iPhone model yet, I'll update when I did.

Thanks again

Hi,

Based on the version number I assume you are using the iOS version. You can see the updates in that version here, and the only change that I think could be relevant is this, which could disable pipe-lining.

Which iPhone model and iOS version are you using? And which Device Manger version were you using before? Do you see the same speeds if you test with a different iPhone model?
