Module Pin Name
Usage for Platforms
I use a JST 1.0 mm connector and hook up pin 6/8/9 together, solder corresponding pin to USB BT dongle.
It works in M1330 just fine except I can't turn on/off the BT led using either the side panel switch or Fn F2. Anyone knows how the get this part working?
The Dell driver (Widcomm) does not recognize the hardware. Vista native driver works and IVT works.
Why did you join pins 6, 8 and 9? It seems like the pin 9 drives the LED showing whether or not the bluetooth module is on which on my D420 and D430 is green so I assume 2.2V to that line would turn the LED on because it seems to drive the actual LED itself based on the description. And why did you draw power from the 3.3V line? I thought you would use the 5V line because that is what USB uses, and thus you could possibly disable the bluetooth to save power through the device manager in the OS. It seems like pin 6 sends the signal to turn on or off the module which I would assume most USB dongles don't have.
USB modules are now about $2.50 including shipping and are super small so it seems like this route would be a cheap way to go, especially when I have 3 laptops to do this to (D420, D430, and Latitude XT)
I have the bluetooth module installed in a XPS M1330 and will see if my theory on pin 9 directly powering the LED. And if that's the case, you could simply solder the pin 9 line to the LED indicator on the module thus lighting the LED.
