Connect to STM32WB Via Android Programmatically

[WSher.1]

Hello!

I'm trying to build an Android app to connect to my STM32WB device using a custom BLE profile.

I'm able to connect and interact with my device via the ST BLE Toolbox app, but when I try to create a Bluetooth socket within Android studio and connect to my service's UUID, it's timing out.

Is there any documentation out there on how to connect to a custom profile, or how to create a peripheral profile so I can connect within the Android system itself (like headphones)?

Thank you! :)
