I’m using the STM32MP257F-DK and trying to bring up the onboard Bluetooth.
- Bring up the HCI device and start the Bluetoothctl service.
- Scanned for nearby devices, paired with the target device(Android phone), and pairing completed successfully.
- However, when attempting to connect to the device using:
connect 60:0F:6B:88:21:96
- I received the following error:
Attempting to connect to 60:0F:6B:88:21:96
Failed to connect: org.bluez.Error.Failed br-connection-profile-unavailable
Also find dmesg log
