M+ nmea message not right

Hi, I linked my M+ with Nvidia Jetson Xaviern NX devkit, which is an Arm-based linux computer. I set M+ output as TCP server, nmea message format. However, when I check the message on my NX computer, they were look like these:


It missed a lot of information, such as the timestamp.

How can I fix it?

Thank you very much.

Hi @AutoCar,

What tools are you using to read the stream over TCP? If you configure the NMEA stream to be sent over USB, do you get the same strings?

I am using command line “'nc 7777” to check these messages. This is what I am getting:

$GNRMC, , , , , , , , , , , ,*55
$GNGGA, , , , , , , , , , , , , ,*48

You have position ( latitude/longitude) coming in on the Emlid Flow app ? Antenna and cable good?

Is your antenna outside? The NMEA will not populate unless you can actually see the satellites and calculate a position.

Hi @AutoCar,

I’d check the suggestions that others have left above, as this may eliminate the issue. If that doesn’t help, please let me know.
