WITMOTION WTRTK-982 - Main service is off or malfunctioning. Nothing could be displayed here.

[enuro12]

Describe the bug Main service is off or malfunctioning. Nothing could be displayed here. Is displayed on the web page

To Reproduce Steps to reproduce the behavior:

1. Go to IP of the Raspberry PI

Expected behavior Honestly i have no idea, this is my first build.

Software/Hardware (please complete the following information):

• RTKBase latest
• OS: Raspberry Pi Os 32bit
• SBC Raspberry Pi 4
• GNSS Device: WITMOTION WTRTK-982
• https://www.amazon.com/dp/B0CY3HYRWG?psc=1&ref=product_details
• Connection type: USB

Screenshots Here is the screen shot of my GNSS Settings i used. https://i.imgur.com/sQI882F.png

Additional context Using this reciever with AGOpen appears to function. Don't know how useful that is to know.

Hello,

Considering that the WITMOTION WTRTK-982 uses the UM982 module from Unicore Communications, and RTKBase was not originally designed for this specific use case, I recommend reviewing the following issues:

Right RAW messages types for RTKbase https://github.com/Stefal/rtkbase/issues/343#issuecomment-1820650503

Add support for operating Unicore modules (e.g., UM980). https://github.com/Stefal/rtkbase/issues/351

In addition, I also recommend checking the following discussion from AgOpenGPS: https://discourse.agopengps.com/t/is-the-um982-an-f9p-killer-for-aog/13960

Normally, I use RTKBase with several UM980 modules (the 'sibling' of the UM982, with a single antenna) to set up temporary bases, and the results are good. In one of the issues I mentioned above (the one I initiated), I discuss the branch I created in my fork of RTKBase to handle the UM980. However, the user @Jef239 developed the necessary features to integrate Unicore receivers into RTKBase (also mentioned in the referenced issue).

I’m not sure what application you are pursuing with the 982, but if it’s not related to an auto steering system, I wouldn’t recommend using a Raspberry Pi 4, as they consume a lot of power.

For UM982 you can use GNSSOEM/UM980_RPI_Hat_RtkBase . There will be a new release based on the new version of RtkBase in the coming days. You cam see it in dev branch.

@geofis Thank you, I'm reading the other information you provided. Would a Pi 3 or 5 do better?

@Jef239 Thank you!

@enuro12 Regarding the question...

@geofis Thank you, I'm reading the other information you provided. Would a Pi 3 or 5 do better?

... it will depend on the use case. If it’s a rover for traditional surveying, I would prioritize battery autonomy, in which case I’d choose a Raspberry Pi Zero W (not even the Zero 2W) or a microcontroller (ESP32, for example). If it’s a base that will be powered 24/7 from the grid, then the RPi 3 or 4 (the 5 isn’t necessary, and the 4 is actually unnecessary) will be useful. I’ve been running a base for several years based on an RPi 3, powered by the grid (in fact, I don’t even use an enclosure in this case). If the use is for a ground vehicle (UGV, autosteer), then performance is a priority, so the RPi 3 or 4 will be ideal, even the 5, depending on what operations the system demands. However, the folks at AgOpenGPS have a lot of experience, so I’d recommend visiting that forum. If it’s a UAV for post-processing, weight and battery autonomy are critical, so I’d prefer a Zero W or a microcontroller.
