I manually restarted and bluetooth just do not turn on. Tried some actions with AI help but did not worked. Here a summary (also generated by AI about what i've tried): Bluetooth Troubleshooting Report for Ubuntu Issue: Bluetooth is not functioning on an Ubuntu system. The bluetooth.service is active, but the Bluetooth adapter cannot be activated. System Information: Operating System: Ubuntu 24.04.3 LTS Bluetooth Adapter: Qualcomm Atheros QCA9377 Summary of Diagnostic Findings: The hardware was correctly identified and detected by the system (lsusb, lspci). The bluetooth.service was running correctly. The rfkill tool confirmed no software or hardware blocks were active. The hciconfig command showed the hci0 interface with a DOWN status and a zeroed BD Address (00:00:00:00:00:00), indicating a failure to initialize the hardware. The command sudo hciconfig hci0 up returned the error Can't init device hci0: Connection timed out (110), confirming a communication failure between the software and the hardware. The bluetoothctl list command returned an empty output, meaning the bluetoothd daemon could not detect any available controllers. It was confirmed that the system is already running the latest available kernel (linux-generic-hwe-24.04). Solutions Attempted: Restarting the bluetooth.service. Reinstalling bluez and related packages. Checking for and confirming the presence of the necessary firmware files in /lib/firmware. Implementing a systemd script to manually load the firmware on boot (later reverted). Attempting to use a third-party firmware loader from a GitHub repository, which failed due to the repository not being found. Reverting all changes made to the system. Conclusion: Based on the results, the problem is not a simple misconfiguration or a missing package. It is a low-level issue most likely related to a bug in the Linux kernel's handling of the Qualcomm Atheros QCA9377 adapter's firmware initialization.
