Bluetooth Toggle

[machx0r]

By nature I'm lazy, I'll spend hours writing applications so I can shave mere seconds off repetitive tasks. To that end I'm looking to write an application that when launched will toggle the bluetooth state. I've looked at the Broadcom/Widcomm SDK but they don't seem to expose any methods to disable/enable the radio.

I've determined that the "StackMode" registry key at HKEY_LOCAL_MACHINE\Software\Widcomm\BtConfig\Gener al controls the bluetooth state when the stack is loaded (0 = off, 1 = on, 2 = discoverable? [not sure about 2]).

It appears as though BTTray.exe loads the BT stack.

At first it looked like it'd be as simple as:

1. Kill BTTray.exe
2. StackMode = StackMode == 0 ? 1 : 0
3. Launch BTTray.exe

This seems to work fine if the device booted with Bluetooth turned off and it has never been started. However once the stack has been loaded once this process results in an error message: "There was an error loading the Bluetooth Stack (0x1).", everytime BTTray.exe is loaded and BT stops working until the device is reset.

Seems like something else is holding onto, and keeping open, the BT stack but I'm not sure what. Any suggestions are greatly appreciated.

I knew that search function was good for something ;)

That's a nice little hack that certainly accomplishes what I'm looking for. Would still like to find a solution that allows me to toggle programatically rather than by emulating keypresses so I can monitor for and recover from any failure conditions.

On a related note does anyone know how to copy files that are located on the ROM. Maybe if I could look at BTTray.exe or wrlsmgr.exe it would help.
