Yes. If you see any issues when testing this functionality, then let's us know in this devzone thread.

Thanks Aleksander Nowakowski! Our developer is away for this week too and will try it as soon as he gets back. Just curious but would there be someone else we can ask for help after trying it out when you are away?

Version 4.9.0 released with requested feature. I hope it will work. I had troubles with replicating the exact scenario, but... just try it. Should be fine.

Hi, expect a new beta release in ~30 min. I'm leaving for 3 months after today so hopefully everything will work. Please let me know when you try the new version.

Hi, sorry, but I thought it will be a quick fix, but found out I need to do some more work and testing, as in that scenario the lib should both try to reconnect and scan. I'm busy with other tasks at the moment but should come back to this soon.

You may test next week of course, if didn't make it before end of your day.

Aleksander Nowakowski — Fri, 18 Sep 2020 04:59:31 GMT

You may be right. When the peer data are passed, the bootloader advertises directly with empty adv data, which will without not be reported to the app at all, or at least will fail to pass the Dfu peripheral selector test, making it impossible to comment in any of the cases.

I'll improve the lib today to and will ask you to try it before I will release, is that ok for you?

Thanks!

I tried this PR before but it only works with the firmware which has deleted dfu_app_peer_data_set.

So, when we suggest our iPhone users to DFU the product for this "delete dfu_app_peer_data_set" workaround, it will be a very bad experience that they need DFU our product firmware first, then update our iOS app for the PR you mentioned for the future DFU.

What we need is a iOS DFU library which can work automatically with BOTH firmware that delete dfu_app_peer_data_set and not, to avoid 1 star of our product and companion app in App Store.

Thank you very much!

Hello,

Have a look at this PR: https://github.com/NordicSemiconductor/IOS-Pods-DFU-Library/pull/374

It added this flag: https://github.com/NordicSemiconductor/IOS-Pods-DFU-Library/blob/fc7e0fb2d4cb28df4590028a0a2b91e02e3894ba/iOSDFULibrary/Classes/Implementation/DFUServiceInitiator.swift#L191 which needs to be set to true if the lib is to look for a new MAC address in Legacy DFU.
