System & hardware:
- OS: Ubuntu 18.04 LTS
- Mouse: Logitech M337
Symptom:
After reboot/sleep, Bluetooth mouse won’t get connected again. Need to remove and pair again to make it work again.
Steps to solve this problem:
1. Update bluez.
sudo add-apt-repository ppa:bluetooth/bluez sudo apt install bluez
2. Remove paired mouse. (If it is paired before)
3. Open terminal, follow the script from: https://ubuntuforums.org/showthread.php?t=2390542
Please note the 01:23:45:67:89:AB is your Bluetooth controller and 34:88:5D:87:C0:A6 is your mouse, it will be different with your scenario.
[bluetooth]# list [bluetooth]# select 01:23:45:67:89:AB [bluetooth]# show [bluetooth]# power on [bluetooth]# scan on [bluetooth]# scan off [bluetooth]# pair 34:88:5D:87:C0:A6 [bluetooth]# connect 34:88:5D:87:C0:A6 [bluetooth]# trust 34:88:5D:87:C0:A6
Then Bluetooth mouse should automatically connect after reboot/sleep.
