Ah, geez... Isn't it always that way? I'm using an iPaq 4150 and a Dell X30. But does this mean that communicating between the PDA and a Desktop is also going to be "touchy"? Or is this "other" stack really common and the MS BT stack less so? -Rick -----Original Message----- From: comodev-bounce@xxxxxxxxxxxxx [mailto:comodev-bounce@xxxxxxxxxxxxx] On Behalf Of dick_grier Grier Sent: Monday, August 08, 2005 9:07 PM To: comodev@xxxxxxxxxxxxx Subject: [CoMoDev] Re: BlueTooth? Hi Rick, These APIs only work with Pocket PCs that employ the Microsoft BT stack (not all do). Otherwise, you have to use the developer kit for the stack used. I forget the name of the most common one, but I'll look it up and post it.
