GPS not locked

 

I was hoping maybe someone might be able to help. I've tried without success to get the map feature to work with an external GPS unit. In the lower right hand corner of the map page it says "GPS not locked" and my coordinates show as zeros. I'm currently running D-Rats v0.3.9 on a Windows 10 Home (64-bit) system. The GPS unit works with windows and all of the other apps. Interestingly, when I monitor the status of the satellites being tracked by the GPS unit, it shows no fix while D-Rats is running. Then immediate upon closing D-Rats, it works again... gets a fix and shows real-time tracking data. Reproducible every time. On a side note, I've been unable to make the external GPS feature work with D-Rats on my RPi either. Any thoughts? Thanks in advance
 

Double check the following under your GPS settings in Preferences.??Make sure you are telling D-Rats the right Comm Port that the GPS unit is connected to and then make sure the baud rate for the unit is correct.??Some GPS units operate at 4800 baud and others at 9600.??If the wrong rate is input, D-Rats won’t be able to talk to the GPS.??I have run GPS/Glonas units, the little white dongles, on my set-up and they work every time.??Those run at 9600.??I have also used mag mount GPS receivers with equal success.??

Another problem, if you often unplug and replug USB cables a lot of times the Comm Port assignments will get changed on Windows machines.??Today, the GPS is showing it is on COMM 5, but disconnect a few cables and now Windows says it is on COMM 3.??Go to the Device Manager and check to see which Comm Port the GPS is registered on.

I wish it were so simple. I should have mentioned that I confirmed the correct COM port was selected and the proper baud rate is set for 9600. Thank you though, much appreciated.

I've tried two different GPS units with no luck. It shows the satellites connected on U-center app when on Sensor API, but not Location API. Google maps is able to locate me as well. Both units appear to be working, except with d-rats. Any thoughts?
