Very good troubleshooting
Honestly I see no reason the first setup should not work. I assume everything is at 57k so that just leaves the app itself. I have not checked recently but will do so now.
Second android setup has only worked for me with one out of four different radio sets (3DRv1). Unfortunately I misplaced my v1 radio at some point and have not been able to investigate further.
Ok tried the latest next windows package and along with the matching android gcs extracted out of the .tar package and it works fine on my F3 sparky target through uart bt. If the objects all populate and system health monitor is active in win gcs via bt I really don't see why it would not work for you with android bt.
