We are having issues connecting to to the Verizon Mifi GPS port. It works intermittently. When we lose wifi, the gps connection is lost and it does not come back on reconnect. Also we see errors "could not set DCB" and "gps data found but no position obtained".
We have to reboot and reset port a few times to get it going again.
When we directly connect to the GPS Com port, it works more reliably but on eof our applications needs gpsgate to work correctly.
