Disabling Glonass to turn on Beidou in Linux. Currently using cat to observe data from EVK-M8T evaluation kit.

0 votes
Hello,

I am currently connecting a EVK-M8T evaluation kit to a linux machine through USB. I am just using the command "cat /dev/ttyxxx" to observe the messages.

I am just seeing GNGLL, GNZDA, GNRMC, GNVTG, GNGGA, GNGSA, GPGSV, GLGSV, GNTXT messages. From my research it seems these are from GPS and Glonass satellites.

**Is there any way I can view the messages from Beidou satellites? Or a way to configure the evaluation kit in a linux platform?

Thanks.

The NMEA messages and Talker ID would be managed via UBX-CFG-NMEA

The constellations can be selected via UBX-CFG-GNSS

Could I also do something like...

echo -e "\xB5\x62\x0A\x04\x00\x00\x0E\x34" > /dev/ttyxxx

and then a.....

cat /dev/ttyxxxx

I tried it but nothing seemed to change.

Well the device should respond immediately, and you should review if you get an ACK or NAK type response.

Walk this through on uCenter in Windows until you are comfortable with the functionality and interaction.
You've got a suitable antenna, and Beidou satellites are visible from your location?
After playing with u-center a bit more I finally understood the UBX-CFG messaging part.

On Linux I have two terminals open. One with cat and the other for sending these messages. I am able to configure whatever I want now and observe the changes.

Thank you for the help the last couple days.
As for Beidou, I don't see anything on u-center yet
