My MacBookPro (Retina, 15-inch, Mid 2015) do not see any Bluetooth device. So I can't connect external wireless mouse and keyboard and this is annoying.

This is a log from a Bluetooth Packet Logger.

Does anybody know how to solve this issue?

I've had the same things happen over the past 6 months (mine's a mid-2012, thought). I've tried to find out the root cause on many occassions - but I'm pretty sure it's a culmination of many, many different factors (wear and tear, bumps/drops, formatting drives repeatedly, etc.). Just found this though:

§ UHE Button Operation: Your Bluetooth USB adapter may have UHE button, this is applied in the condition when computer system is without BTW driver installed but need to make connection with Bluetooth enabled keyboard or mouse or any HID devices

I also use iTerm2, which is notorious for provisioning issues (can't have a worse problem when it comes to the command line).

Bluetooth gets in the way a lot (for me), so I've messed with the settings quite a bit. I wouldn't be surprised if the same was true for you. Likely through iTerm as well, which worsened the situation.

The largest cause seems to be from inconsistent settings, firmware upgrades, and the kernel issues that come with them. Doesn't take long for it to start taking a toll on the battery, power settings, and worsening kernel panics, kind of like this (old but relevant): https://forums.gentoo.org/viewtopic-t-506162.html

You will have to dig deep. But the issue is buried under some random setting, plugin, or other microscopic detail. Find the source, then patch the kernel appropriately.
