Broadcom Bluetooth

Is there a way to detect if a Broadcom Bluetooth device is turned on using
code?

Thanks to Unc, I know how to set the device:

HMODULE hBFM = LoadLibrary(TEXT("BtFlightModeCtl.dll"));
if (hBFM)
{
HRESULT (WINAPI *OEMSetBthPowerState)(DWORD);
OEMSetBthPowerState =
(HRESULT (WINAPI*)(DWORD))
(GetProcAddress(hBFM, TEXT("OEMSetBthPowerState")));
}

where:
OEMSetBthPowerState(TRUE)
turns a Broadcom device ON

and:
OEMSetBthPowerState(FALSE)
turns a Broadcom device OFF


But, if the device is already turned on when I start my code, I want to
leave it on whenever I am done.

I don't know the answer, but just based on your code I'd be inclined to at
least try to GetProcAddress for something that looks like one of these:

DWORD OEMGetBthPowerState();
DWORD OEMGetBthPowerState(DOWRD *state);

Who knows, you might get lucky.

Good advice!

m_OEMGetBthPowerState = (HRESULT (WINAPI*)(DWORD*))(GetProcAddress(m_hBFM,
TEXT("OEMGetBthPowerState")));

...and it worked!

Is there any way to dig tools out of an API?

You're just lucky. Mine won't turn off using that API. :-)

I think you're talking about the equivalent of "depends.exe" (Dependency
Walker) which you'd use on a PC. I don't know if there is one for PPC.

Hey Unc,

Have you seen this site?
http://tinyurl.com/2xlh2s

The url will redirect you to the TekSoftCo website.

I was just given this site myself a few minutes ago, so I can't tell you if
it will be a wealth of help.

It is a wealth of help. It doesn't perform exactly as advertised but I have
turned the thing off and on. Seems to work sort of randomly but I'm sure
that will be figured out.

Thanks, JP and thanks, Radu!

I'd like to know where you get these "unpublished" ordinals and calls from
:-)

EEEEK!

I used the .exe file, it turned off all devices, and when I tried to turn
them on again, the Bluetooth device and tray icon have both "disappeared".
My PPC is telling me to insert a module to turn it back on!

Still, it's doing *something*

Sounds like you are having a good time over there, chap!

It certainly makes one appreciate devices on the shelf that has
functionality built in that works every time!

Certainly am. I've found workarounds. That Radu is one smart cookie :-)
