Hello- I am trying to update the sampling rate of the HerePro GPS. In the user manual, it says it can be set up to 20Hz, but I have not been able to find how to change this. Any and all help would be appreciated, especially if I am missing something incredibly obvious.
Thank you!
Any luck on this? I am doing the same. I try to connect using u-centre and it’s shows connected but I don’t think it is actually. I don’t get any data from it. Therefor I believe you can’t change the log rate etc. I think what you have to do is use Mission planner and go into the UAVCAN area, connect to the receiver with the passththrough option then try to connect with U-centre. I will test tonight. I assume that is where we can change the log rate. I am looking to lot at least 10hz on the drone for PPK. I don’t mine removing some constellations in order to do this if that is what the receiver needs.
Select only 2 constellations that work best in your area, usually GPS and Galileo or GLONASS using the GPS1_GNSS_MODE parameter.
Then set GPS1_RATE_MS to suit your requirements, but I doubt 100ms will be achieved. The default 200ms (10Hz) is normal, maybe a Here Pro can do better.
Thank you for your reply, it is appreciated.
I believe you have a typo for clarity. 200ms is actually 5hz and I believe you are correct in that this is supposed to be the default logging rate for the herepro set as rover.
However my current tests show it’s only logging at 3hz (even though all settings are set to 200ms)
I was also considering reducing the constellations down to the two you mentioned and trying for 10hz because this is what we have set on our swift nav receivers and acheive excellent results.
I have no interest in RTK whatsoever. I only want to use a PPK work flow.
I have so many questions regarding things like what is available over the usb for external logging devices such that if the onboard HerePro computer can’t handle all constellations we can log with an external device but there is no documentation on the interfacing perif that I can find.
There is enough space on the Herepro for PPK flights especially if we can reduce the messages to only those required for PPK and two constellations.
My flights are 40 minutes but even this should be OK.
Any chance you know someone who is also working on this type of functionality?
I am also hesistant to update the F9P receiver FW because I don’t know if it will be compatible with the herepro perif FW, not to mention that it seems the only way to connect to the receiver is to enable serial communications over UAVCAN first (even though it say for here 4) then make changes to the receiver or update firmware over that.
Even here I am not sure any changes will remain persistant becuase I am guessing that the receiver is setup every time by the herepro perif and will overwrite any modifications you make to the receiver itself.
Too many questions 
If you can put me in touch with someone at hex that would be great or someone who knows the answers
