Bluetooth Going Out Intermittently?

2012 Mac Pro 5,1

My bluetooth keeps going out intermittently - it's not my mouse, as there is a squiggly line going through the bluetooth symbol up in the status bar. Resetting the SMC seems to be the only remedy. To add to the weirdness, even a wired mouse won't work when this is occurring. I still have to reset the SMC to get the mouse - any mouse, wired or bluetooth - working again.

Anyone else seen this issue? What's going on?

Curious if you've tried using a USB Bluetooth adapter to remedy. I switched to Logitech unifying receivers after issues with bluetooth on the MacPro 5,1 years ago (Apple Mouse behaved extremely erraticly). Believe they were caused by interference, but unsure. Did add a cheap USB bluetooth dongle to the wired keyboard when I ran into those issues. Maybe that helped?

This is the one currently using:
IOGEAR Bluetooth 4.0 USB Micro Adapter, GBU521

May be it's actually an USB issue, but not BT issue. The BT on 5,1 is USB connected. If USB has issue, then it will explain why both your BT and wires mouse stop working.

I routinely see this issue when booting between Sierra and High Sierra. Rebooting again normally will solve it. I have an upgraded WiFi/BTLE card for Continuity and 802.11AC support - so I blame it. But rebooting to the same OS seems to rarely cause it.

Another culprit is when you quit VMware. It routinely seems to take down my BT driver. Restarting Vmware or plugging in a USB device often resets the issue, but there times I have to reboot. I have an optional Razer USB mouse connected for gaming, so it is only a minor inconvenience.
