Bluetooth Hp Pocket PC 5450 and Windows CE 4.2 API

TheMSsForum.com: The Microsoft Software Forum

I am trying to use the Windows API to discover and communicate with Blue
Tooth devices. When I call WSALookupServiceBegin it works ok but
WSALookupServiceNext fails with 10050 Network Failure. Has anyone
successfully used the windows API to control the Blue Tooth on a iPaq? The
code for WSALookupServiceNext is below.

PBYTE pOut = (PBYTE)LocalAlloc (LPTR, MYBUFFSIZE);
if (!pOut) return -1;
WSAQUERYSET *pQueryResult = (WSAQUERYSET *)pOut;
for (i = 0; i < nMax; i++) {
dwLen = MYBUFFSIZE;
dwFlags = LUP_RETURN_NAME | LUP_RETURN_ADDR;
rc = WSALookupServiceNext (hLookup, dwFlags, &dwLen, pQueryResult);
if (rc == SOCKET_ERROR) {
rc = GetLastError();
break;
}

Hi,
Several reasons prevent you from using the CE 4.2 Bluetooth functions:

1st. The h5450, even with the WM2003 upgrade isn't a 'plain' CE 4.2 device.
If you look at the WM 2003 SDK you'll see that not all the CE 4.2 BT
functions are available on WM 2003
2nd. Those API functions are intended for devices using the Microsoft
BlueTooth stack. The h5450 use the Widcomm BT stack...

To control BT programatically on the h5450 you should use the Widcomm SDK or
the one from http://www.high-point.com

Alberto Silva

I have Toshiba e800 WiFi. Question: which CF or SDIO card uses Microsoft
Bluetooth stack, so that I could use it in my Toshiba?

I've been using the SDK from Highpoint and it works well on the h5450
device.
