Hello everyone, my name is Massimo, and I’ve created a control unit that performs a series of operations both remotely (via SMS) and locally (via BLE).
I have a OnePlus 12, and until Android 14, everything worked perfectly: the Bluetooth connection was fast and error-free.
Since upgrading to Android 15, the connection happens instantly, but the app takes a few seconds to recognize it, resulting in an attempt to connect to a device that is already connected. On Android 14, the LED would stop blinking (connected status), and the app would simultaneously emit the connection sound while displaying the signal strength I implemented in my app.
On Android 15, the connection occurs instantly, but the app takes a "long" time to recognize it, often causing a connection error. I’m attaching two videos showing the behavior of the Bluetooth module and the app on both Android 14 and 15. Thank you all for your attention.
