Any source for a WT41 - USB Dongle for Windows that will work right out of the box with the Windows or Broadcom stack i.e. plug it in the USB port, pair it using Windows and get a virtual com port? We are thinking of using WT41 in remote devices and it would be nice if there was an off-the-shelf WT41 - USB Dongle that our customers could buy i.e. without us building and programming the dongle. The Broadcom Class 1 dongle I have now works great but would like the WT41 dBs on the dongle end.
The only WT41 USB dongle that I'm aware of (actually pre-built in a dongle form factor) is this one from an outfit in Australia:
The datasheet link on the esdn.com.au site appears to generate a server error, but this one works:
I believe this is not exactly what you're looking for though, since it has a built-in FTDI USB-to-UART bridge IC on the back of the board. It's meant to provide a simple interface to iWRAP, but not to USB HCI mode, and the module is (not) reprogrammed accordingly to boot automatically into that mode. I am pretty sure it wouldn't make sense to do so in that design, since there's no way to switch to a direct USB connection anyway.
If you need a design like that, you would probably need to roll your own.
OK Jeff thank’s. As regards using WT41 as PC dongle USB CDC Host mode, it would be nice (and I bet increase sales) to provide a binary file or group of files that if sent to the WT41’s UART (with any appropriate delays between files), would cause the WT41 boot into PC dongle USB CDC Host mode with interface to PC through its built-in USB port. That way each dongle could be programmed by anything that can send serial data stream from file.
Just a WT41 and regulator would provide a complete dongle. Icing on the cake if one could use Broadcom 2046 Bluetooth 2.1 USB UHE Dongle Driver on PC side.
It would be nice to have binary files to switch your LE stuff to one of several different modes also. That would boast sales.
