NMEA GST message for LC29H (DA)

IoT Modules GNSS Module
1

Hello,

my LC29H (DA) arrived today and it seems to work well, except one point. For my use I need the NMEA GST message to get the Horizontal Accuracy and Vertical Accuracy.

The command $PQTMVERNO58* gives me the following for my current firmware version:
$PQTMVERNO,LC29HDANR11A03S_RSA,2024/03/19,13:55:31*20

How can I activate the transmission of the GST message?

Thanks a lot in advance,

Thomas

If GST is still not available in the latest LC29H (DA) firmware, please provide an update to support this feature.

Hi @thn80
Hello, the LC29HDA module does not support GST messages. There is no development plan at present.

Very bad to hear this :frowning:
Is there any other NMEA message on the LC29H (DA) that outputs the accuracy of the current position?

There is not much need of a GNSS RTK module if there is no information available on the accuracy of the position.

Thanks,

Thomas
