connecting Libre 3 with DiaBLE App and Watch
Hi,
I tried your code and built the iOS App on my iPhone. Now I try to connect my freestyle libre 3 sensor with the app. But it is not possible to connect the libre 3 sensor. In settings I selected the "libre" tap and I tried to find my chip. It connects but then disconnects. What could be the reason that my iPhone does not connect to the sensor. The original Freestyle Libre 3 app works with the sensor.
Is that a problem with the 'get session info' that I saw in your TODOs?
Here is my log

Thank you Anubhav for your PR! There have been many forks of DiaBLE in the past but none submitted the implementation of new features.
I have been publishing a public beta on TestFlight for only a couple of days and now I must proceed very carefully in applying major modifications to project.pbxproj.
Could you please try refactoring your extension by putting it in a DiaBLE/DiaBLE/Widgets subdirectory as Glucose Direct for example is doing in https://github.com/creepymonster/GlucoseDirect/tree/main/Widgets ?
I tried by myself to add a Widget Extension target from Xcode 15.2, using DiaBLE.xcconfig as the configuration base (ff3ee94) and adjusting the WidgetsExtension.entitlements and Info.plist’s paths to point to the DiaBLE/Widget subfolder where I gathered them (d39afe6).
It compiled fine but, when I tried to run the WidgetExtensions scheme, Xcode was crashing almost immediately so I reverted the commits in main but left them in the dev branch: https://https://github.com/gui-dos/DiaBLE/commits/dev
