Hello all,

I'm currently testing bluetooth for querying measurement devices.
So far, I have a test-application that connects to the device via
virtual COM-port and communicates fine (most times).
Sometimes (rarely), I get error 59 (which appears to be
ERROR_UNEXP_NET_ERR) when opening the COM-port (Createfile).
If this happens, I'm not able to stop this problem until I reboot.
(Meaning I have not found a way to connect to the device).

Does anyone know where this error originates and what can be done to
eliminate it?

Any help greatly appreciated!

Thanks in advance,
