Bluetooth will not work on my HP laptop. It will not find any of my devices even though the two devices I'm trying can see each other.
I am new to Linux. I am running kernel 4.15 with all the latest updates.
In trying to fix this problem I have installed Blueman which may or may not be getting in the way.
Thank you in advance for your assistance.

Re: Bluetooth not operable "Searching for devices"
Status update. I'm still struggling with this issue and bluetooth is still now working for me.
From the research I've continued to do it looks like the drivers I need are not available until kernel 4.17. I recently upgraded to kernel 4.15 to get my wireless to work (Thank you Jeremy). I tried to install the 4.17 kernel but it didn't seem to work. I'm now in the process of upgrading to Linux Mint 19 and hopefully the 4.19 kernel. I am going to open another post because I can't find anywhere which says that the 4.19 kernel will work with Linux Mint 19 (or 18.3 for that matter).
Once I get this working I'll post again in case someone else has this same issue.

Easiest way to manage kernels is with ukuu:

4.19 will work with LM19, but didn't try it for long before reverting to 4.15.

Re: Bluetooth not operable "Searching for devices"
now i have the same problem, but i haven't been fiddling with any kernel changes nor has there been any updates installed. it just stopped working as expected after i smashed my first on the mouse pad out of frustration due to an unrelated issue i had...
