looks like I have the same issue.

to reproduce:

add scale in Bluetooth settings
create a new user
use scale and connect Bluetooth after a few seconds a list of radio buttons appears and instantly the app crashes.

I switched to v2.4.3. Now Bluetooth data transfer works again.

Dec 30 '21 14:12 Stonerocker

dev version works similar to v2.4.3. However, it crashes on first attempt to connect to Bluetooth device.

Dear oliexdev,

First of all, thank you for your app ! Very good !

But, I am also facing a bug with openScale (downloaded from F-Droid) when triying to add a Bluetooth device: it crashes.

Thank you very much.

Best regards,

I add that, to make it work, I installed v2.4.0 from Github and then updated to v2.4.6 (from Github also). Thanks.

@ivasemma-6872 you need to grant the FINE LOCATION permission to search for Bluetooth devices.

@oliexdev

Today I have tested your app the first time and was wondering why it always crashed.

After having set all permissions to allow the app works perfectly fine.

Thanks for the advice.

I would appreciate if you could increase the font size (especially in the table section) as it is very hard to read.
