FIXED: Intel 7265 bluetooth issue

Support
1

I’ve been searching the Internet and this site for several days, read a ton of stuff, and found many similar issues which mostly resolved. None of the threads on the right (“similar to”) helped. I apologize for having something that seems similar to dozens of other threads but my issue remains intractable. The Arch wiki seems to have the best info on troubleshooting bluetooth but I was not able to correct the issue using that page.

Any help would be appreciated!

My Manjaro KDE system is up to date. I have a working bluetooth dongle so I know the bluetooth subsystem is fine.

I’ve recently added a TP-Link Archer T5E card. This PCIe card hosts an Intel Wireless 7265 M.2 card.

Wifi is working perfectly with this card. Bluetooth on this card does not work nor is it recognized. The small BT USB dongle has been removed.

This was an old card of mine and indeed bluetooth was working. Let’s see what rfkill list say.

:point_up: I have a ThinkPad with such card - no issues

It doesn’t find the card. Nothing in “rfkill list”.

I’ve tried booting from the Manjaro install USB, also. It doesn’t find the BT, either.

$ rfkill list
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no

I see, I don’t want to go this far so quickly, but it’s also a stupid experience of mine. Can you check the card to see if both antennas are properly connected? One case I had back then was one of them was loose, forgot which one but basically both need to be connected.

If that’s fine, then I will need another output from sudo lsusb -v | grep -i bluetooth -A 2 and inxi -E. This card, despite connected through PCIe, will have its Bluetooth functionality registered through USB.

Let’s hope you don’t get a hardware defect, though.

Perhaps the man-in-the-middle - the Archer card does not identify the BT on the 7265.

To correctly troubleshoot this, you should attach the card to another system - a laptop preferrably - and verify if BT then works.

It is entirely possible that bluetooth is disabled an you have to enable it.

You have not mentioned what backend you are using for bluetooth … or the environment as a whole.

I appreciate the help.

leledumbo, the antennas are connected with tiny wires which seem to be properly secured.

$ sudo lsusb -v | grep -i bluetooth -A 2

$ inxi -E
Bluetooth:
Message: No bluetooth data found.

I appreciate your note, linux-aarhus.

It will take me a few days to test the 7265 M.2 card. I have a buddy who may be able to help and this system does have an M.2 slot that may prove helpful (but no Windows OS with which to test).

For what it’s worth, the box this card came in is literally labelled “AC1200 Wi-Fi Bluetooth 4.2 PCIe Adapter”.

Just a quick reminder… Many PCIe cards with M.2 have a USB port that you must connect to your motherboard’s F_USB connector. I believe that card is one of them. Check the manual that came with it.

Good luck

You are hella correct.

Sorry to take so long to circle back. It took a few days to find the cable.

It works well with the cable. This was never an OS problem.

I really appreciate the help. Hopefully, this thread will help someone else in the future.
