This exact bug happens all the time for me on calls for more than around 2min. The Bluetooth connection fail also happens during dialling - often on the first call after a connection is established.
The only way to re-establish a connection is to disable bluetooth and then re-enable it, and the fastest way to ensure it works is to put the phone in flight mode and then turn that off again. device: bq Aquaris E4.5 OS build number: OTA-10.1 Ubuntu Image part: 20160408.4 Ubuntu build description: Ubuntu 15.04 - armhf(20160408-211605) Customisation Image part: 20160324--36-54-vivid Car: Skoda Octavia 2013 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1555608 Title: Bluetooth "Connection timed out" during a longer call To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1555608/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
