Fragen zur Ardumower-GPS-App und zum Mähverhalten

[Raschl]

It´s already connected. I can drive the motors, swich on the mower-motor.
But I have no fix of the GPS although both GPS-RTK-electronics itself have a fix.

It seems to me that the NTRIP client has no connection to the base.
Please check in the ESP32 Xbee software for basis and client that all IP addresses are set correctly, described here: https://wiki.ardumower.de/index.php?title=Ardumower_Sunray#RTK_base

You still have #define GPS_CONFIG true?

In the console window, during boot, right before the IMU calibration does it say GPS OK? If not, try to swap RX and TX on GPS. You have IO ref to 3.3V?

If you are connected to the arduino and have the console window open, then upload a new program, it you will catch the hole start sequence.

 

[Raschl]

No I have "#define GPS_CONFIG false". I have Board 1.4 and I read or saw somewhere that I then have to use false here.

 

[Holmis]

Try to use true

 

[Raschl]

It worked partially. I now have actualized signals of GPS.
Now I have to wait for a fix.

Please also have a look at the new monitor-picture.

 

[Holmis]

Have you set the position of the base in the APP? Use Absolutte and input aproximatly where the base is placed. Then give it some time

 

[Raschl]

can´t get a GPS fix of the rover any more now.
Can switching to #define GPS_CONFIG true be the reason?

 

[Holmis]

Yes, then it load comfiguration from Grand Central M4.

 

[Raschl]

So how should I fix this now?
true= no rover fix but comunication with app
false = GPS-fix but no comunication

 

[Holmis]

Try to connect to the Rover GPS with USB and u-center while it is set to true. Maybe you get some hints.

Are you using wifi or the MR/LR between base and rover?

 

[Raschl]

The GPS is not connected to my Router. I don´t know how the two are comunicating.
I thought they have a direct radio-connection.

What do you mean with "while it is set to true"?

 

[Holmis]

#define GPS_CONFIG true
and connect to the GPS with usb to your computer at the same time to see if you find something out. I use the WIFI version with www.rtk2go.com so I don't know anything more about the radio communication between base and rover than what the Sunray Wiki says

 

[Raschl]

Acc instructions it is not allowed to connect it to usb while it is also connected to the mainboard and the rover is switched on.
I´ll try to reconfig the rover GPS and if that does not work I´ll start a new threat in the GPS-Folder.

Can the free version of the EVO-viewer be the reason for the problems?

 

[Holmis]

Have you tried expanding the buffer as image attached shows?

 

[Holmis]

As shown in image you should not setup the rover, only the base. The rover should set it self up.

 

[Raschl]

Have you tried expanding the buffer as image attached shows?

Yes I did this acc to the lastest tutorial video.

As shown in image you should not setup the rover, only the base. The rover should set it self up.

Yes, but if it doesn´t work?

 

[Holmis]

Then I am out of ideas. Try to do it step by step from scratch maybe?

 

[Raschl]

Holmis, anyway, thanks for your great support up to here.

 

[Raschl]

Es ist vollbracht!
Nachdem ich die Antennen (die einzeln über u-Center im Haus ein 3D-Fix hatten) nach draußen verlegt habe, haben beide GPS-Platinen jetzt ein FIX angezeigt.
Das wurde aber auch erst in der BASIC-App angezeigt. In der Free-Version hatte ich trotzdem ein INVALID.
Jetzt geht´s an den Einbau im Mäher und Aufzeichnen der ersten Karte.
Danke an alle nochmal, die mich bis hierher unterstützt haben.
