Version

1.8.0

Companion app

NRF Connect

[Joshndroid]

Mine doesn't even get that far. I am also on 1.8.0
I tried with gadgetbridge with the .bin and it says "Element cannot be installed"

I downloaded and installed NRF Connect and tried with the .zip
Mine gets to 0%, reboots (3 times total) with it getting to 0% and fails out.

Getting exactly this in the NRF Connect app logs

[Avamander]

Have you tried something besides NRF Connect?

[yuval-herman]

I tried the dfu zip and gadgetbridge twice and everything worked fine

[sssmack]

Siglo did not work for me (using that from the pinephone - non Pro)
Siglo reported "The firmware update has failed. Retrying the update will fix it in most cases".
I re-tried about 20 times with no change in response from Siglo.
No whining from me here. :) The purpose of my post is to provide more info. to you - whom I greatly appreciate your time and effort on the software. I have been letting my regular job and family take my time.

[Avamander]

Maybe it's worth changing the ambient radio environment, might be noise that causes the uploads to fail.

Rebooting all components in the setup as well, but you've probably done that.

Moved to another part of the house sadly the same result... Also have been rebooting like a mad man as well as repairing device multiple times. Can't even flash the same firmware thats on it, let alone anything else.

[sssmack]

I changed the ambient radio environment and rebooted both devices .
After doing that, the download and install worked the 1st time and as well as all of the previous downloads and installs.
Thank you!

[yuval-herman]

Have any of you had similar issues before 1.8?

[Joshndroid]

After 6 attempts using my PinePhonePro and Siglo on Manjaro ARM i was able to get it flashed. Never had an issue with my android phone in the past. Kinda weird but yeah

[yuval-herman]

I think this might have to do with previously configured secure pairing in ble

[yuval-herman]

did any of you configured secure pairing?

[Joshndroid]

Is that the "companion device pairing' in gadget bridge? I had tried that both off and on if so

[yuval-herman]

I have a suspicion it might have to do with this I will check on my PC soon

[yuval-herman]

I'm seeing a lot of strange changes in NimbleController namely in line 189 and the gav event switch but also in general, see full diff.

I can't investigate further at the moment...
