My Logitech M557 bluetooth mouse does not pair with Ubuntu 16.04 LTS.
I opened the Bluetooth settings window of Ubuntu, which indicates that Bluetooth is "On". I selected the "+" button to start the Device Search for all device types. I turned on the power switch of the M557 mouse and then pressed the "pair" button, which starts its blue pairing light to blink. The M557 is not found by the search.
I changed the device type to "Input devices" in the Device Search window, but the result is no better.
Also, I attempted to pair a JBL speaker, and that did not work. Bose headphones do not pair either. I also changed the "Visibility" switch for the computer in the Bluetooth settings window, which did not help.
The computer is a Dell Inspiron 15.
Any help would be greatly appreciated.
