The device is a product designed by my company that uses the InTheHand DLL. I believe the firmware code base is C#, but I'm not sure of that. I am using a PC with a USB Irda dongle to communicate to the device using a program developed in LabVIEW.
Your second option is what I need to know; how to find out what the Service Name is in the device code. The firmware guys have been using a library with the InTheHand DLL embedded, so they're not really sure where the Service Name is set within the code (the library was developed before they were with the company).
I know you wouldn't know anything about our specific firmware, but I thought maybe there was a function call in the DLL where the Service Name is set, so that I could instruct the firmware guys to look at what they are sending in that function call?
