Bluetooth Serial port - Com Port number

Hi Guys

I picked up a Bluetooth OBD2 dongle to use torqueBHP with my smartphone but i was wondering, ive got some other OBD scanning tools which i used with a serial cable and an old laptop.

I tried to hook up the bluetooth dongle with them but it defaults to COM7 and in the bluetooth settings com7 is the only option, is there any way i can get it to use com1-4 or that i can redirect it to the lower com ports which are the only options within the scanning software?

Ive checked Device manger and it shows 2 com ports which are 6 & 7 neither of which have the advanced settings tab which would allow the port number to be changed

Any help much is much apreciated

  1. This Microsoft article looks like it will help you.
  2. Hi

    That looks like it should do the trick

    when i try and run it from the command prompt it cant find it

    C:\windows\system32>change port /query
    'change' is not recognized as an internal or external command,
    operable program or batch file.

    Ive had a quick search around google for any other documentation for the commands but came up empty other than afew forum posts with people having the same issue

    is this something i need to download from somewhere or otherwise enable within XP sp3?
  3. Never mind. . .That is for Terminal Services :(
