bluetooth devices no longer connect to the system

[Craig Magina]

Up until some recent trusty update (maybe a week or two ago), bluetooth worked fine, but after the update none of my bluetooth devices connect to the system, nor can I add new ones. The devices I use are an LG HBS-700 headset, an Apple Keyboard and Trackpad. I plugged in an Asus atheros based bluetooth dongle to see if it was the Broadcom driver no longer working, but I have been unable to get that to work either and it has also worked successfully in Ubuntu before. I ran the bluez-hcidump command that was suggested, but it complains about no device being found.

Status changed to 'Confirmed' because the bug affects multiple users.

Before the update i had to run bluez-simple-agent to get bluetooth working. Now it just does not find the device. I tested bluetooth with a usb bluetooth dongle, and bluetooth transfers work, given that bluez-simple-agent command is running. I can even discover the native bluetooth adapter through the usb bluetooth dongle.

The following dump is made by 'enabling' bluetooth in the unity-control-center. This only lasts a limited time, before the hcidump utility crashes due to the 'Can't open device: No such device' message.

After the latest update, bluetooth is working without a problem. No workaround is required. However, bluetooth breaks after suspend resume. Following is a hcidump of a suspend resume action.

It affects a non-essential hardware component (removable network card, camera, web-cam, music player, sound card, power management feature, printer...).

I just installed 14.04 on a new notebook Acer Aspire E17 and wanted to connect my bluetooth speakers and my bluetoth mouse but none of them gets recognized. I tried some additional bluetooth devices without success. Following the bluetooth setup guide in the ubuntuusers forum I found that everything is installed as expected and according to the blueman applet in the panel bluetooth is working. On my older notebook still running on 12.04 everything works fine.

Has somebody tried some bluetooth in 14.10?
