Hello,

I’m trying to obtain GPS location on the EG25-G. I have used the following antenna - LTE Main & Diversity & GNSS Triple Port u.FL Antenna - 100mm - Sixfab.
The LTE stuff works as expected. However, I keep getting the CME Error +516. Here is a screenshot of the module output. Any help is much appreciated.

Hello Felix,

Thanks for the help. I took the modem out to open skies and was able to obtain a GPS lock. However, I would like to improve the functionality using GNSS. But whenever I upload and try to flash xtra2.bin and change the time to syn the new file. The GNSS still reads the file from the 1990s.

Is there a script for uploading and flashing new GNSS data properly? I would assume that once flashed, the GNSS data binary does not revert to the old one on reset.

Thank you!

Hi,

I have a device:

The device has a built-in LTE EG25-G module (installed drivers: Quectel_LTE&5G_Windows_USB_Driver_V2.1). Unfortunately, I do not know what antenna is mounted inside, because I cannot find such information on the manufacturer’s website.

I have the same problem as above… GPS location doesn’t work when I use LTE connection.

When I unscrewed the housing from the LTE module, it turns out that the antenna is only connected to WAN port.

Can the reason for the lack of GPS communication be the lack of an appropriate antenna built into the tablet, and so it needs additional connections between the antenna and the module to GNSS port, or maybe could it be the drivers fault?

Thanks in advance!
