My Base is fixed position and rover is movable. I have connected ground pin at Base to ground pin at Rover. I have connected Tx2 at Base to Rx2 at Rover by wire. I have configured Base and Rover. But i haven’t get 3D/DGNSS/Fixed.

I had an issue regarding the same. I am using 2 ZEDF9P for getting centimeter level accuracy. The base is directly connected to the rover via UART2, as suggested in the integration manual of ublox. I have all the necessary messages enabled on the base and rover, also given in ublox datasheet. Ucenter is even showing Fixed solution, but still after mapping those coordinates, the readings are inconsistent. Both rover and base were kept 3-4m apart in static position and the base is configured in SurveyIn mode. You may ask for any necessary information you need to know. Your help would mean a lot.

thanks you saved me a lot of time!

Love your work ! – and thanks for the plug for Aussies’ contributions – we’ve been playing with mowers for many decades !
Quick question (I hope) – I just want good quality UTM coordinates for remote boundary surveying on my farm, and am trying to get an RTK setup going using two SparkFun Surveyor modules (Zed-FP chipset), and two Sparkfun LoRa 1 watt radios (SparkFun LoRaSerial Kit – 915MHz WRL-20029).
After about a billion iterations of parameters on U-Centre etc etc, I am finally getting an RTK fix between my PPP Base and Rover – BUT it is very intermittent – maybe 30 seconds, and then back to Single fix (Using SWMaps as my Rover GUI).
I don’t need speedy updates, just accurate, long distance (approx 1-2 km forested country), reliable coordinates.
In short, have you any experience with these radios ? and/or suggestions to “get the settings right” ?
Thanks in advance – I owe you 1,000 beers !
Best Regards,
Jeff
PS – yes I’ve tried everything !!! 🤣🤣

Can I contact rover with Android like SW Map? if yes how can I do so. Please answer

Please help me with what I could be doing wrong.

Should it may help anybody in the F9P community, this is a link I posted on GrabCad this morning. It contains a self-designed 3D printed enclosure to host your EVB-C099-F9P modules (STL files). You just need a 3D printer and 6 screws. Enjoy.

For anyone using ardusimple boards: there is a IOREF pin, that needs to be connected to 3.3V.
Otherwise, you can’t use the UART ports.

Hi Jason,

Were you able to perform in moving base setup? I couldn’t bring it to Fix Mode: TIME.
