Bluetooth Keyboard Not Recognized as Input Device on Raspberry Pi 4B Running OSM Cinnamon Linux (version 5.15.92)

Bluetooth Keyboard Not Recognized on Raspberry Pi 4B Running OSMC (Linux version 5.15.92)

If you're having trouble getting your Bluetooth keyboard to work on your Raspberry Pi 4B running OSMC (Open Source Media Center) with Linux version 5.15.92, you're not alone. This issue can be frustrating, but there are some steps you can take to troubleshoot and resolve it.

Checking the Connection

First, make sure the keyboard is properly connected to the Raspberry Pi. Turn on the Bluetooth keyboard and place it in discoverable mode. On the Raspberry Pi, open a terminal window and type:

 sudo hciconfig hci0 scan
 

This command will scan for available Bluetooth devices. Look for your keyboard in the list of devices. If it's not there, try restarting the Bluetooth service:

 sudo systemctl restart bluetooth
 

Pairing the Keyboard

Once the keyboard is detected, you'll need to pair it with the Raspberry Pi. Type:

 sudo bluetooth-ctl
 

This will open the Bluetooth control center. Type:

 scan on
 

Wait for the keyboard to appear in the list of devices. Once it does, type:

 pair 
 

Replace with the address of your keyboard. You'll be prompted to enter a passcode. Most keyboards use the default passcode "0000".

Checking the Input Device

After pairing the keyboard, check if it's recognized as an input device. Type:

 cat /proc/bus/input/devices
 

Look for your keyboard in the list of input devices. If it's not there, try restarting the input system:

 sudo systemctl restart input-utils
 

Checking the Kernel Module

If the keyboard still isn't recognized, check if the Bluetooth keyboard module is loaded. Type:

 lsmod | grep btkeyboard
 

If the output is empty, load the module:

 sudo modprobe btkeyboard
 

Updating the Firmware

If none of the above steps work, try updating the Bluetooth firmware. First, update the package index:

 sudo apt-get update
 

Then, install the firmware:

 sudo apt-get install --reinstall firmware-linux-nonfree
 

 
 
If you're still having trouble getting your Bluetooth keyboard to work on your Raspberry Pi 4B running OSMC with Linux version 5.15.92, try the steps outlined above. They should help you troubleshoot and resolve the issue. If you need further assistance, consider reaching out to the OSMC community for help.
