Whenever I remove and re-pair my bluetooth GPS receiver, Windows 10 assigns a new COM port pair and increments the port number. I am now at COM24 for the output port and BktTimeSync seems unable to list available COM ports over COM20. Can you possibly add support for higher COM port numbers?
Thanks & 73,

I found a work-around solution to this after much searching. Windows marks COM ports as used once they are allocated. Bluetooth Devices keeps incrementing the COM ports when you re-pair the GPS because it thinks the old COM ports are in use. You need to go into regedit and change the value of HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\COM Name Arbiter\ComDB - you can find details at
http://www.ftdichip.com/Support/Document...gistry.pdf - every COM port has a bit in the ComDB value that is set to 0 if it's available or 1 if it is not. So you need to change the 1's to 0's and then you will once again be able to assign the lower COM ports.
No, that method will not work Mauro if the COM port number has been used before and the bit was never reset in the ComDB registry key. I tried that method first and it told me the COM port was already in use so I had to go into the registry and clear it.
