Ubuntu develop image from OOWOW
How can I confirm if my bluetooth hardware is broken, none of the os’s I have installed have bluetooth. I have tried armbian and ubuntu, but I cannot enable bluetooth in Gnome. Also unavailable on FydeOS
Hello @Egert
Have you installed the antenna?
Hello @ivan.li
Yes I have attached these antennas, wifi works okay, bluetooth used to work.
I disconnected the antenna and reattached it, but no change unfortunately. I looked at the photos online to confirm that my antennas are also connected as intented.
Hello @Egert
The antennas has better to attach before SBC boot. Hot-plug will cause something unexpected.
I disconnected the antenna and reattached it, but no change unfortunately.
By the way, may I know the reason?
I was just testing if perhaps my antenna was not properly attached to the board. That is why I removed and reconnected it.
Hello @Egert
When you disconnect the antenna, wait for a while and the Bluetooth device list will change.If the antenna is not connected, there is a high probability that other Bluetooth devices will not be found.
In my case, I cannot even enable bluetooth.
I get this message “Bluez daemon is not running”
Hello @Egert
Burn the firmware below. If Bluetooth is not available yet, I need you to provide some log information.
khadas@Khadas:~$ dmesg | grep Bluetooth
Hi @ivan.li
I am not able to boot up this image. I tried installing it through oowow, but after reboot i get into oowow and not ubuntu os.
I tried khadas@Khadas:~$ dmesg | grep Bluetooth
With a different ubuntu image, but I get no output, so I guess bluetooth hardware is not recognized. Where bluetooth is located on the board, perhaps I have damaged it?

Hi @ivan.li
I got it running now using the rkdevtool. Unfortunately no bluetooth. I will check if I can see any damage on my board that could be the issue.
Hi @ivan.li, did you manage to resolve your bluetooth issue? I have the same problem. Recently installed Ubuntu 24.04 on my Edge 2, and I’ve just installed it in to a case with new antennas. WiFi working, but no bluetooth. Took it apart again, reconnected the antennas, same issue. I’m wondering if Ubuntu doesn’t have the necessary driver for the bluetooth chip.
Hello @tonybaynes
Can you check the latest image (edge2-ubuntu-24.04-gnome-linux-6.1-fenix-1.7.2-241022.img.xz)? Bluetooth should work.
Hi numbqq, I did as you suggested and I’m very pleased to report that this has solved my issue. Thank you! My Edge 2 now has Bluetooth working perfectly. All I did was reinstall the version of Ubuntu that you suggested.
