Xiaomi mi body composition scale 2 stopped syncing after update to 3.0

[stribor]

Describe the bug
I used 2.x version for a while and synced without problems, app got auto updated to v3.0, and it is not syncing anymore 'Failed to initiate notify' message appears briefly

To Reproduce
Steps to reproduce the behavior:

1. As usual stand on the scale/do measure
2. Start open scale to sync with scale
3. if it not auto syncing, click on Bluetooth button
4. See error popups "Waiting for measurement via notifications" followed by "MIBFS:Failed to initiate notify"

Reproduced with latest version from f-droid (3.0 (70)

Expected behavior
To get measurements like it used to work.

Heads up from my side, mine seems to work after some more attempts.

[nonvenomous]

I'm experiencing the same issue.

I'm able to sync single data points when timing weighing and trying to connect. So only the "real time" measurement and none of the history entries.

Kinda how the Xiaomi Bluetooth Mi Scale - openscale Wiki describes at some point

Unfortunately I could only receive the weight data if a user was on the scale and a connection was established.

[cmmata]

I'm able to sync with my Balance Feet (I think it's v2, but not sure) with the 3.0 update. But it takes some time. Basically, I do this:

• open the app
• click on the bluetooth icon, to activate it
• I use the scale
• then I see the same pop-up like the one mentioned above, something like cannot notify
• I wait for several seconds (30 or more), and then suddenly it syncs with the scale

With the previous version, I usually opened the app, wait 3-5 seconds to find the scale and then synchronize with it.

I can provide with logs, if I can do it from the mobile app itself (I don't have development environment for Android)

[senz]

Can confirm issues with MIBFS sync and CSV backups import.
Rolling back to 2.5.3 fixes both issues.

[AlphaDE]

Same problem here and obviously database was converted, app crashes when just installing the previous apk. So no way back to the previous version.

[denharad]

While troubleshooting, I tried rolling back, couldn't import my CSV, then reinstalled v3 & restored my backup. During the restore, I had to re-add the scale & now it's working properly with my history intact.

Can another affected user try re-adding the scale under "Settings -> Bluetooth" or restoring a backup to a fresh install.

[shilin-da]

Can another affected user try re-adding the scale under "Settings -> Bluetooth"

Deleted the scales and added them back. Nothing has changed: the error persists, measurement results are not received.

[nonvenomous]

Can another affected user try re-adding the scale under "Settings -> Bluetooth" or restoring a backup to a fresh install.

Somehow it kinda worked? Error message popped up but sync did work.

Steps I took

• create backup
• delete user data and cache, then uninstall
• reinstall 3.0 from f-droid
• stand on scale for a moment to turn on
• go to settings -> bluetooth, give permission, select scale
• click on bluetooth button on main screen, got asked to create user
• restore backup
• connect per bluetooth, error message pops up, but 8 records got synced (which I previously deleted when trying this)
• disconnect
• stand on scale to weigh
• step off, click main bluetooth button, error message pops up but new record is received

Will see if it keeps working over the next days.

[UltraSalem]

I've got the same issue. Just updated today in the background, went to sync my latest measurement but the interface was horrid and cluttered, it had forgotten the mi scale, and when trying to add it fresh and sync got the same notify error as OP

[kowalcj0]

Apart from the sync issues with MI 2 scale, I've also noticed that the measurement of muscle % drastically dropped by 32%! from 68% to 36%

[alexanderadam]

In my case also the historical weight values dropped. Was there a faulty conversion? Or is that a setting that needs to be changed? 🤔
