Hi
Me and my team designed a custom PCB containing a STM32wb55cc and needed it to be connected with BLE with an application made by ourself.
Unfortunately, even if ou board is functionning pretty well with STM apps like with STM32 BLE toolbox for Android for example, with our own app made on App Inventor we can't manage to establish a connection between our microcontroller (the server) and one of our cellphones with the app (the client).
We went through a lot of topics in ST Community forum and didn't seem to see the same problem somewhere else. We also went through some workshops provided by STM over the BLE function but we didn't find any solution.
If you need more details about our project feel free to ask.
We hope we were clear enough about our issue.
Best regards
