Hey everyone I have two tractors i’m running AOG on. I made a stupid mistake on my Deere 6230 and shorted my 4.1 board to 12v when pulling it out to make updates requring me to toss it and build a new one due to frying the FP9, xbee, and most likely the teensy. Needless to say i started a new one from the ground up, since i had a few extra 4.1 boards from my intial order. I was running 6.2 AOG on it, and i also have virtually the same set up in my Deere 4640. With the rebuild I updated everything in the 6230 to AOG 6.8. downloaded the whole new git hub package for the teensy, FP9, ect. From an auto steer stand point everything is working great again, but my RTK has been spotty at best. It takes maybe 5 minutes or more and moving around to register RTK, then it only lasts for about 1 minute before timing out. it comes and goes even with a line of sight to the base station broadcast antenna. I’m pretty sure it isn’t a hardware issue, because i can see the xbee via remote from the basestation one, and the hardware as far as radio antennas is the same between tractors. I can tell when it kicks in because the tractor wants to shift one direction or the other by over 16 inches, and when i lose the signal it shifts back. I’m assuming I have a settings issue/firmware issue one one of the boards because my 4640 still has a perfect RTK signal in the same field with no issues at all. I’m pretty sure the Xbee is configured propertly, as that is pretty easy to remote into via XTU to check all the settings. I’m assuming then it might be in the firmware on the teensy, AOG settings, or FP9. Thoughts on where to start? I haven’t pulled the unit out of my 4640 yet as i’m planting with it still, and it takes the removal of several brackets to get to it but i was thinking of when i’m doing planting pulling that board to check the FP9 configuration on it in Ucenter, because i honestly can’t remember what settings i used. I was hoping someone here might have a few easy ideas to try first on the 6230 or knows what changed between the versions. I thought about just trying to find the old 6.2 version and loading it onto everything, but open to suggestions first.
This is slightly different than you were thinking and I have no experience with xbee but maybe check that the gps antenna is making a good connection. I had one once that was if it wiggled a certain way would drop out and make it loose rtk. You could see it on the screen as a bigger fix to fix distance all the sudden.
I actually just found the issue. I’m pretty sure i had the same issue 3 years ago, and just took bad notes when i was writing what i did in my lab journal. It is a baud mismatch on the Teensy 4.1 file. The default for RTK is 9600 from the GitHub File, and the xbee is using 115,000. I just made that code correction and problem solved. The more i think about it, I’m pretty sure i had the same issue and asked the same questions back then, forgeting this step. My memory is not as good as it used to be!
