I am running a Toshiba Satellite L755D laptop, debian testing (recently upgraded from jessie), MATE desktop with Blueman bluetooth manager. I was trying to pair a new tablet (running Android 6.0) to my laptop using the Blueman graphical manager. Unfortunately, regardless as to whether the pairing request was initiated by the tablet or the computer, I got the normal pop-up request on the tablet requesting verification of the pass code, but nothing ever came up on the computer. In the past, I got a popup notification to verify the pass code. Once the pass code was verified both on the computer and tablet, pair completed, and the device was usable. But, as no notification showed up on the laptop, I could not pair the device.
After a little looking around on my system (I maintain a complete set of tools for cli maintenance, just in case), I was able to use bt-device to get the MAC address of the tablet and pair it. Once paired, I was able to connect using Blueman, and was able to transfer files via bluetooth both directions. Given this information the following questions present themselves: 1) Is there a setting somewhere that will cause this issue? 2) Is this a known issue with Testing or Blueman? 3) Is there a solution which will allow use of Blueman for pairing? Clearly, the kernel and drivers on the system are working correctly, or I would not be able to accomplish the pairing with bt-device. I suspect the problem is with notifications, either in general, or with Blueman specifically, that is causing the problem, and that were I to be getting the notification I expect, I would be able to accept the pass code and proceed normally. -- 73's, WB5VQX -- The Very Quick X-ray
