NEMA Sentence selection not Saving in Facet L-Band V3.6 ?

GPS/GNSS Development Boards

I want the Facet L-Band to report the NMEA_DTM sentence. It’s the first on the List of available messages.

When I change the NMEA_DTM Message Rate to (1) and save then exit, I still don’t get DTM messages.

The next time I check the firmware, the NMEA_DTM Message Rate is back to (0), like it’s never being saved to the Facet Device.

I’m spying on the stream via Bluetooth ComPort w/ Tera Term. Also tried Lefebure NTRIP Client’s Log File.

I’ve looked while using only SBAS (WAAS), only PP L-Band, NTRIP, and with various combinations available. Still no DTM messages seen.

I’m I doing or assuming something silly ?

TIA,

Ryan

Setup performed via WiFi

Saved to Profile 1

RTK Firmware: v3.6

ZED-F9P Firmware: HPG 1.32

Perhaps try one of the other config methods and see if that works https://docs.sparkfun.com/SparkFun_RTK_ … with_wifi/

Also be sure to save settings (if available) back out of menus fully afterward…any change?

TS-Russell, thanks for the Reply- that got me closer .

I just changed the config via serial, and both the Facet(V3.7) and Facet L-Band(V3.6) both retained the setting for the additional DTM Sentence.

However, neither output the DTM(Datum) Sentence.

Maybe this requires a FW update on the F9P ?

[UPDATE] - My Mistake.

I finally found the DTM Sentences in the NTRIP logs, which makes sense.

They are not pushed out the serial port with other NMEA Sentences apparently.

Thanks for reporting!

I can replicate the problem with WiFi config not working (but serial is). Issue can be tracked here: https://github.com/sparkfun/SparkFun_RT … issues/646 We’ll try to get a fix soon.

They are not pushed out the serial port with other NMEA Sentences apparently.

All ZED messages, once enabled, are reported over BT, WiFi, and to the SD log. They are also reported out the DATA port if configured. They are generally not reported out the USB port as that is used for config and ZED debugging. Were you expecting to see them over USB? You would need to enable them using u-center specifically for the ZED’s USB port.

DTM not getting saved over WiFi should be fixed in the next release.

Yes, but this makes perfect sense to me now.

Thanks for the help everyone !

No problem and thanks for finding that sneaky bug!
