Hi folks (and @PaulZC ), Searched but didn’t find anything on this topic. Wanted to run it by here before opening anything on https://github.com/sparkfun/SparkFun_RTK_Everywhere_Firmware/issues . Running RTK_Everywhere_Firmware_v2_3.bin on SparkFun RTK EVK . I noticed a couple things watching/parsin…

Only 1005 is gated via completion of Survey or Fixed Position. The other MSM4 or MSM7 will output.

Hi Doug ( @doug_f ), Just FYI: the way the GNSS is configured by RTK Everywhere is changing. In the next release, that part of the code will be very different. In 2.3, the configuration is defined by Base vs. Rover mode and the entire Base or Rover configuration is applied - when changing mode or ma…

Thanks @clive1 & @PaulZC . I wrote some code to parse & display RTCM message attributes - so I saw what you described. I’m surprised RTCM messages are sent immediately, even during a survey-in. IMO it seems counter-intuitive since a fixed location for the base has not been established. But then I h…

Thanks Doug ( @doug_f ), After a Factory Reset on EVK, I see the following in Base \ RTCM Messages: [image] It looks OK to me… Are you looking at the Rover RTCM Message rates? Those are all zero. Best wishes, Paul

The MSM messages are observations, not corrections in the adjustment sense. The Rover receiver can solve for the Base position, it’s just not anchored in a way a “difference” can be computed. The moving base doesn’t use 1005, and RINEX generation would be fine without the base position. The data c…

Thx Paul. No, I was in to Base mode when I checked. Maybe this explains it. The path you took was Configure Base —> Set RTCM Message Rates, and your default rates appear correctly. I was on the enable/disable RTCM messages (sorry, rushing I said “rates"). So, shouldn’t that menu show enabled me…

Hi Doug ( @doug_f ), Menu 2 (Configure GNSS Messages), sub-menu 2 (Set RTCM Messages) sets the RTCM message rates for Rover. Is that what we’re discussing? Do we need to make it clearer that those are Rover rates, not Base rates? [image] Hope your travels go smoothly - all the best, Paul

Hi Paul ( @paulzc ), Menu 2 (Configure GNSS Messages), sub-menu 2 (Set RTCM Messages) sets the RTCM message rates for Rover. Is that what we’re discussing? Yes. Do we need to make it clearer that those are Rover rates, not Base rates? Yes, I think that would help. I’m flying blind since my EV…

OK - thanks! Issue opened here: [EVK] Menu GNSS Messages - Rover RTCM Messages - labelling is unclear opened 05:59PM - 18 Dec 25 UTC (UTC) [image] PaulZC …

Thanks Doug (@doug_f ),

After a Factory Reset on EVK, I see the following in Base \ RTCM Messages:

It looks OK to me… Are you looking at the Rover RTCM Message rates? Those are all zero.

Best wishes,
