I installed Windows Mobile 6.0 Pro SDK on an XP machine today. From what I understand, the device emulator has now rolled to v2.0 and this is now the version used for Windows Mobile 5.0 development also. I had been using the Mobile 5.0 device emulator and its peripheral serial port mapping to a Bluetooth virtual serial port connection to my custom device. From what I remember it used to work pretty good on 5.0.
Now since I installed the 6.0 v2.0 emulator, I am having problems with the Bluetooth serial port connection on while debugging using the emulator platform for the PocketPC VGA.. device. It seems I can get connected fine at first, but then when I go to reconnect, the port is not available even though it opens ok. My serial port code was the same as for the 5.0 sdk. When I debug the same code on the PocketPC device itself, I can open/close/reopen/close read/write reliably. For now I have dropped back to the PocketPC device platform. Has anyone else run into any similar v2.0 emulator peripheral serial port mapping operation snags?

This is a known bug in the V2 CTP. It is fixed for the future versions of Device Emulator releases. As a work-around, please remove the "/u0" switch from the command-line and after the emulator launch, use File->Config dialog to enable Serial Port binding.
