Hi Everybody!
I try to start on the on GitHub - eringerli/RpiNtripBase
How (and where) to config usb-serial adapter? On my RPi its /dev/ttyUSB0
Thanks
You might be asking the wrong person because I failed miserably with the RPiNtripBase. I had the F9P sending RTCM3 messages to usb on the Ardusimple board then plugged that into the Pi. But I couldnāt get it to work. I might try again now I know Iāve got a working system.
The ESP32-Xbee software on a normal esp32 dev board works perfectly.
Can you explain how do you use ESP-Xbee ? Is it also casters via internet? or just by radio?
Internet. The esp32 has no radio capability beyond wifi and bluetooth. It sends to your local network.
Do you have a link to the esp32 you are using and to the program you are using as well as how they are linked?
Any ESP32 Dev board.
The software.
How to install it.
Wiring is easy.
ESP32 pin simpleRTK2B pin
--------------------------------
GND to GND
RX0 to RX2
IOREF to 3v3_OUT (both on RTK2B)
The IOREF connection ensures that the RTK2B board communicates with the ESP32 at 3.3 volts, which the ESP needs.

Hi all, iām just in the process of setting up my base station on the bench and would like to double check a few settings if possible,
In the UBX-CFG-PRT, i have set UART2, Protocol in as RTCM3, and Protocol out as RTCM3 with a baudrate of 115200, Is this correct? SHould i also disable the other ports, i.e UART1 Protocol IN/OUT ānoneā? or leave as is.
In the UBX-CFG-MSG, I have enabled 1005,1074,1084,1094,1124,1230 on UART2. Also are all the NMEA messages necessary or should i disable/enable a certain few?
I have set the location in TMODE3 to fixed mode and entered the lat/long coordinates which i got from www.maps.ie, they seem to be very close to the lat/long from U-center.
Lastly i have my NTRIP caster sending to rtk2go as base mountpoint āballymagorry85ā it seems to be mostly working ok, however the 1005 msg doesnāt appear but iām still working on that problem.
Any tips/changes you would recomend before i move onto the rover?
As a base I donāt think any of the nema messages are necessary.
TMODE3 got my lat/long accurate to less than 50mm in about 31 hours I think. I just set it to 50mm and 12 hours. Both criteria have to be met so it ran on till it got the 50mm. I then entered those coordinates into the fixed position.
Odd how 1005 isnāt there. Just checked and as you say, it isnāt. Is it definitely set to the correct port? 1005 doesnāt need to be sent as often as it is just your base coordinates. Most seem to set it to every 5 or 10 seconds.
I canāt comment on the CFG-PRT. I used the standard base config file then modified it to suit. Not sure how they are set in my base and itās in the office so canāt check right now.
Others will be able to give more detailed advice. Iām learning fast, like a lot are here!
Thanks Alan, I might try to survey in the unit and see if that has any effect on the 1005 msg, Iām fairly sure I have it enabled, will check again tho, the whole āsend & saveā aspect has caught me out before.
Definitely a lot to learn & learning more everyday!
Is u-centre showing Time mode and the fixed coordinates when the base is running? At the right hand side.
The whole u-centre setup thing is a bit odd. Easy to trip up and not very intuitive.

Yep, seems to be showing the fixed coordinates, I just started it on a survey in for the same as you tried and will check back in the morning, just double checked and the 1005 msg is enabled so should be ok there.
Did it say TIME in green below the coordinates?
Are you referring to the data window on the right of the screen? If so, the TTFF is reading, 27.547sec and the fix mode is 3D. I think I need to get my antenna into a better position as well, really trying to get the basics down before I put it into its final position, wonāt be as easy to work on when itās up on the roof
Yes. If it says that itās not in fixed base mode. Are you saving settings to flash memory or is the thing reverting back to previous settings on startup?
Anytime I make a change I highlight all 4 options in the UBX-CFG, and hit send, think Iām ok on that end.
The fix mode sounds like the problem, Iām only getting 3d and not Time, Iām getting a proper antenna mount set up on the ridge of the house tomorrow so will try again with that. Iāll post an update when I get it up an check the feed
Have you tried uploading the Ardusimple base configuration file?
Good Man Alan, I think youāve cured it, 1005 msg seems to be working! I believe the last time I tried to upload the base config file I changed it to generation 9, I now see they still use the older Ublox m8/8 file format! Thanks for persisting with me!

Iāve probably inadvertently helped but sometimes just someone suggesting things theyāve had trouble with helps!!

Oddly you 1005 is showing up on the rtk2go caster table but not if I relay it in snip and show the RTCM3 messages.
