some bluetooth error?

pear@PearBook-Air:~/comice-control-center$ ./comice-control-center 
cat: /sys/class/bluetooth/hci0/rfkill3/state: No such file or directory
Traceback (most recent call last):
  File "./comice-control-center", line 71, in do_activate

    powered_on = int(result)

Maybe I did something wrong?

same issue for me too @alxb421

For me at least the problem was here: the state of BT is getting this file /sys/class/bluetooth/hci0/rfkill3/state, in my case i had no rfkill3. So I went to the folder and looked what rfkill do I have. Turns out I have rfkill2 there so you just change that in python file.

Hi guys! @alxb421 @kyrus7 @Dyrkon I'm a noob in terms of Bluetooth... I'm trying to understand the rfkill concept.

Can you share me the full path of bluetooth state file? In my case is /sys/class/bluetooth/hci0/rfkill3/state but can be different in your machines or devices. So with that data i can improve the code to recognize better the state of the bluetooth.

You can open a file manager (nautilus, thunar, etc... or with terminal using cat command). And view the content of something similar in the folder /sys/class/bluetooth/<device>/<userspace>/ and find inside the state file the value saved on it.

Regards!

could you please Dyrkon explain to me how did you do that step by step? thanks in advance

if you modify the file ~/comice-control-center/comicecontrolcenter/functions/bluetooth_information.py on line 14, this """cat /sys/class/bluetooth/hci0/rfkill2/state""" to this " ""cat /sys/class/bluetooth/hci0/rfkill*/state""" and updating all BT services should work

also u can modify the hci0 for hci* because the BT controllers in Linux normaly have this prefix

[libredeb]

Fixed!
