Bluetooth does not work for me when I connect the Linux adapter sees it but it says that it is turned off and I cannot turn it on what to do
 


have you checked the output of the command

rfkill

to see if bluetooth is blocked? if it is not blocked and you need to troubleshoot further, it may help to know if the adapter is a usb or is built into the system. either way it should show up in the output of the command

lsusb

if you can post the line that has info about your adapter, that may help.

you could try checking systemctl status bluetooth to see if the bluetooth service is up and running. you could also try checking bluetoothctl show to see if you have a default controller available.

I'm new to linux, so I'll send what terinal linux gives out
 
you could try unplugging the adapter, running the command dmesg -w and then plugging the adapter back in. fair warning: dmesg will most likely output a whole lot of info. you only need to look at or share the messages that appear after you plug the adapter back in. on some distributions, you need root authentication to run dmesg. i am not sure if fedora is one of those. if you get any kind of permission error or no output, you could try running sudo dmesg -w

you are looking for any errors or warnings in those messages that may give a hint about why the controller isn't getting set up.

Bluetooth errors(When i plug in)

if you need a full response from the terminal i can send
 
i wouldn't need to see the full response. if you could include the messages from after you plugged the adapter in, that might provide some context.

i see the errors you posted and those might be helpful. i haven't seen those specific ones before. what i generally do with something like

[ 7041.730181] Bluetooth: hci0: unexpected cc 0x0c25 length: 2 < 3

is run a web search for the end without the timestamp (so this part: Bluetooth: hci0: unexpected cc 0x0c25 length: 2 < 3) to see if maybe someone else has posted a similar thread with a solution.

feel free to post the rest of the messages about the bluetooth adapter near the timestamp 7041.730181 and i can look at those and help you do some web searching after i finish lunch :)
 
this is not the full response from the terminal, but this is the full response from the terminal when i plugged in the adapter

thank you. i think that might be helpful. have you gotten this adapter to work with any other linux distribution?

the reason i ask is this line from dmesg:
[ 7041.688252] Bluetooth: hci0: CSR: Unbranded CSR clone detected; adding workarounds and force-suspending once...
Click to expand...

comparing that against this one from lsusb:
Bus 001 Device 005: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)
Click to expand...

i have seen similar dmesg lines. they seem to say that the adapter is not legitimately a Cambridge Silicon Radio adapter as shown in the lsusb output. the other time i saw those lines, the adapter also did not work so it will be helpful to know if you have been able to use it with linux at all yet?
 
when I bought it it was written that it works with Windows , Mac os , x os and linux 64

and according to your answer, it seems to me that my adapter is not working very sorry, I will check it
 
you don't need to apologize and i'm not trying to say it won't work at all. i was just trying to figure out if you had been able to use it yet.

can you or would you consider live booting something like ubuntu and/or endeavour os to see if it worked with either one of those? since they are both from a different system than fedora, it may help let you know if the device works at all.
 
Yes, the device works with Windows, but refuses to work with Linux. On the Internet they write the adapter does not support Linux, but on the site where I bought it, it says that it does, thanks for your help.
