BlueTooth Com ports and connection to device

We have a situation where we have Bluetooth conectivity to a remote device, this works fine but the connected ports vary. This is the problem. We need the bluetooth to always connect with the same com ports. Two ports are connected one for Data in the other for Data out.

The reason for staticx com ports is for the next phase of the operation which is to read the information from the remote device using a third party piece of software. When started this prompts the user for the com ports in use. This is a medical device and the users are not IT people. The process to find out which com ports are connected is time consuming when peoples lives are at risk. This all happens in the back of an ambulance so the kit cannot be connected all the time.

Solution required could be either:
Fixing the com ports (preferred)
or
Auto displaying which ports are in use to the end user

Can you not use a WMI script?

Not sure if this is directly relevant, but it might help...

Hi,

If you use third party bluetooth software, you can usually specify the com port number on a computer that listens and sends etc.

WidComm and BlueSoleil are the two I have come across. The in built Microsoft software does not offer as much flexibility and there in may lie the problem?

Regards,


RobMobility.

We are not allowed to use a non Microsoft Bluetooth Manager. No support for the software or device if we do.

I did write a script to look at "HKLM\Hardware\devicemap\serialcomm" and write it to a TXT file. This is works fine but now I am told we have to identify the 2 com ports, one which is "Input" and the other "Output". The user needs to know the output only.

The Microsoft Bluetooth manager has this information. So my question is how can I read this information from the Bluetooth Manager and place on the screen for the user. In a txt file or any other method that is usable for a non tech person. I know the user could just look at the Bluetooth manager but this is not what I am being asked to achieve.

Hi,

Would this app enable you to enforce standard COM port assignments?

Thanks Robmobility, this looks like it could do the trick, except the defined input/output ports will not be known. I am off site at present but will be able to test this on Friday.

I would still like to know how to read the BT Manager as this has all the info we require.

Thanks again
Dave

BlueTooth seems to be a law unto its selft. To many issues raised by this so users are now going to check the Manager them selves. We should have told them this in the first place.

Tanks for all your help people.
