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.
