Question: Serra BlueTooth

Lately, I have been experiencing horrible BlueTooth connectivity problems. After a little digging, I noticed bluetoothaudio was dropping frames with errors like,

Too many outstanding packets. Drop packet of 7 frames (total drops:6600 total sent:80153 percentDropped:7.607806) Outstanding:8

This insufferable packet loss makes listening to music impossible. I have tried resetting both my PRAM and SMC. Sometimes it helps, but only for a little. I have also reset my BlueTooth a few times and deleted the plist files before a reboot. Again, this only helps from time to time. I also tried clearing the recent devices from

~/Library/Preferences/ByHost/com.apple.Bluetooth.*.plist

I wrote a little shell script,


#!/bin/bash
# Description - Seems to fix BlueTooth connectivity issues

sudo defaults write /Library/Preferences/com.apple.Bluetooth.plist ControllerPowerState 0
sudo kextunload -b com.apple.iokit.BroadcomBluetoothHostControllerUSBTransport
sudo kextload -b com.apple.iokit.BroadcomBluetoothHostControllerUSBTransport
sleep 1
/usr/libexec/PlistBuddy ~/Library/Preferences/ByHost/com.apple.Bluetooth.*.plist -c "delete :RecentDevices" > /dev/null 2>&1
sleep 1
sudo defaults write /Library/Preferences/com.apple.Bluetooth.plist ControllerPowerState 1
sudo kextunload -b com.apple.iokit.BroadcomBluetoothHostControllerUSBTransport
sudo kextload -b com.apple.iokit.BroadcomBluetoothHostControllerUSBTransport


This seemed to help for a while but still isn't a sure solution.


Any other ideas?


I am truly at a loss to explain how Apple can make some of the best computers and fail at something as simple as BlueTooth.


I'm afraid to update lest it becomes worse than insufferable.

macOS Sierra (10.12.6), null
