Update rate does not get set

Emlid Flow & Emlid Flow 360
1

In TCP NMEA setting I am able to select 5 and 10Hz however when I apply it’s forever being in progress of change (double arrow turning) and never happens (stays at 1Hz).

I tried it thru TCP local network thru web app and reachview android app. I don’t have a serial port and I didn’t found a way to do it thru USB so I figure we can’t.

please let me know what to try.

What is your rtk observation rate set to?

4

It’s the original settings.
Settings are attached in the questions.
It’s of course lower than rover output but I was under impression from the instructions that it doesn’t matter… Am I wrong?

5

It says update rate 14?

I do not work for Emlid, so is that 1,5, or 10hz? or coded info like 4 at 1hz

In short it will not work well if your observation rate is 1Hz, and your position output rate is 5 or 10hz.

Your observation must be the same or higher than the output rate.

Thx unfortunately I won’t have access to it this week. I ll try higher rtk rate when I ll be back and let you know. But instructions are not giving any information for rtk. Probably because you could still use the devise with rtk off… Don’t know…

Hi Charles,

Thanks for sharing the report!

I’ll take a look at this and will try to reproduce it. I’ll get back to you once I’ve any news.

Hi Charles,

Please check your PMs. I’ve messaged you there. We need some sensitive information so that it’s better not to post it publicly.

Hi everyone,

Let me conclude this topic.

There can indeed be difficulty with choosing the 10 Hz output rate when you’re working with the 14 Hz update rate. The update rate has to be divisible by the output rate.

To use the 14 Hz update rate, you will need to choose 1 Hz in the NMEA output rate. We’ll add this information in the docs and in the app.

In case you require higher output rates, please, work with the 10 Hz update rate and the 10 Hz output rate for the Reach receiver.

Hi everyone,

We’ve released the new stable version of the firmware - 26.3 Reach Firmware. Now, it doesn’t allow to set NMEA update rates if the RTK update rate isn’t divisible on it. So, there is no need to perform additional calculations from now on :slightly_smiling_face:

Thanks for drawing our attention to it!
