Hi

It looks you have too many ports and BlueSoleil mixed them up. Unfortunately this is no WCL bug but BlueSoleil bug and the only way to fix it completly delete BS, remove all vCOMs, reset its counter and install BS once again. Just installed BS creates 2 or 3 vCOMs.

"Service not found" means that your device does not have DUN service.

P.S.: On your screenshort I can see two identical ports with number 8 and two COMs with number 3

Hi

As I told you must unpair all devices, uninstall BlueSoleil. Better to remove all USB vCOM device. Delete all vCOMs from system (Device manager). Reset vCOMs counter to initial value. You can set first byt to 03 so vCOMs numeration starts from 3. Then install BlueSoleil.

There is no way to select vCOM to connect to when you use Bluetooth connection.

If you device supports SPP and your code is correct then connection shoudl be established. "Service not found" means that the service you are trying to connect to is not supported by your device.

USB vCOM -> may be you have USB -> COM cables or something: I do not know what hardware do you have but your screenshot shows that there are too many vCOMs/COMs in your system what is not normal.

If you have TeamViewer I can take a look on your system: there is definetly something wrong.

All WCL function returns error code. So check this error code and do what you need then.

while (vCOM.Open() != WCL_E_SUCCESS) {}

By the way, WCL_E_INTERNAL on BlueSoleil usually means that device did not paired

Hi

The While loop is not helping  the message appear and i don't have control on the message box and I need to push the OK button. when I create port the message appear  three times in one create way??.
and the device is paired I check before the create.
I must to find a solution the rest of my App depends on that.

I guess that you did not modify WCL vCOM demo code. So AfterOpen even has wclShowError funtion which generates this message.
