GNSS feature in GL-E750

Technical Support for Routers
1

The LTE cards supplied with the Mudi (at least the EP06 series) supports GNSS (basically, GPS). It would be great if some level of official support was added (GL Cloud locator in case of theft, maybe even location based profile activation or scanning for WiFi networks?).

I’ve tested my Mudi, by installing the gpsd and gpsd-clients packages, however couldn’t get it to work - we have in total 4 ttyUSB interfaces (though gpsd only starts on ttyUSB1 and ttyUSB3), and none of them output legibe data (probably need to set appropriate baud rate, and send the right AT commands to enable NMEA).

Could you please at least give some information about the internals so that at least some minimal GPS/GNSS information can be extracted?

Start gps first by sending AT+QGPS=1 via /dev/ttyUSB2. And read nmea frame from /dev/ttyUSB1 by gpsd.

I covered this in other threads but the performance of the GPS in the Quectel modules is very poor, even with an active antenna. You are better off using a uBlox M8N for your projects with an arduino.

Thanks, will try!

I understand that (even though Quectel boasts about their GNSS capabilities quite extensively on the EP06 subsite…), however it’s not a specific project I want to do, just access to the actual hardware features to toy around with.
