It is no problem for a single device to use multiple virtual COM ports in
the "client" role.

Exposing multiple "server" ports is a bad idea although some
implementations do it. Remote BT devices will query for the COM port using
Serial Port Profile UUID. This UUID should uniquely define one service on
your device but if multiple ports are being exposed on a single device the
discovery app would get multiple results which it may not expect.

I hope this helps.

| Hi All,
|
| I'm just a beginner in WCE 4.2 and I have a question regarding the
| Bluetooth device.
| Is it possible to use more than one "virtual COM" port on an unique
| Bluetooth Device?
| In every example I saw that only one "virtual COM" is build over a BT
| stack but I didn't find an explicity limitation.
|
| thanks
