You need to be outdoor for seeing more satellite
Did you connect gps antenna?
yes connected the GPS antenna. Is it about the SIM data service of AT&T?
No, the gpsfix mode 1 is using satellite only, not agps
Can you check now?

seems it is not having good satellite signal, only 3 satellites are seen.
Are you in outdoor area?
No, i am in indoor, located in Montreal, Canada. My MangOH RED was working perfectly from home.
I just to let you know that I have not got the GPS antenna once I bought yellow.

I don’t know is there any difference or not. But RED was working with the GPS antenna !!!
did your RED see any satellites in AT!GPSSATINFO?
RED board is not powering up, it may be damaged, for that reason I bought the yellow. Is there any issue between GPS and GNSS? On board, RED says GNSS and yellow says GPS !!!
I think this depends on module, not the board…
So antenna is connected well then. What could be solution to get the gps position then?
The satellite signal is not good
you need to go outdoor
How did you configure for RED before as you said it was working fine before?
Using SUPL?
I looked into the previous setup, and no it was not working, we have used manual GPS location to test.
I am trying to install in the laptop and test it outside. However, I am blocked in how to run AT command in WP. Microcom is installed in the current desktop. can you help me out?
You can install the MBPL usb driver
If you have connected the UART2 console, you can type “microcom /dev/ttyAT” to enter AT command
BTW, didn’t you can enter AT command before?
i believe this one
yes, i have used via VS code terminal where microcom is working. However, I am ok with AT commands. No I can go outside to check the AT commands
Yes, i am getting the correct GPS signals once I go outside. I have checked with GNSS commands and it works, getting position information. So, do I need data service to have more accurate position information?
Could you please let me know how can I test the data service as well where I can connect with a server?
You can try the following:
AT!ENTERCND=“A710”
AT!GPSXTRADATAENABLE=1,10,2,1,1
AT!GPSXTRADATAURL=1,“http://xtra1.gpsonextra.net/xtra.bin”
AT!GPSXTRADATAURL=2,“http://xtra2.gpsonextra.net/xtra.bin”
AT!GPSXTRADATAURL=3,“http://xtra3.gpsonextra.net/xtra.bin”
AT!GPSXTRATIMEENABLE=1,30000,10000
AT!GPSXTRATIMEURL=1,“xtra1.gpsonextra.net”
AT!GPSXTRATIMEURL=2,“xtra2.gpsonextra.net”
AT!GPSXTRATIMEURL=3,“xtra3.gpsonextra.net”
AT+CGDCONT=1,“IP”,“your_APN”
AT!GPSFIX=2,180,300
Please see the attachment for the log.
The following commands did not work
AT!GPSXTRADATAENABLE=1,10,2,1,1
AT!GPSXTRATIMEENABLE=1,30000,10000
AT+CGDCONT=1,“IP”,“your_APN”
AT!GPSFIX=2,180,300

is it working for you?
I can see gnss command returning location
You might also monitor the result by AT!GPSSTATUS? and AT!GPSLOC?
