Hi, I think this problem can be extended for all bluetooth devices. I also paired an android (OS 7.0) phone, after sleep mode you can not reconnect the phone any more.
This issue is related with ubuntu bionic 18.04 (this problem was not present in ubuntu 16.04). -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1767292 Title: The bluetooth mouse cannot connect after sleep mode.
