After I did the whole thing, it showed I was off by 26 inches? Why? I have no idea. But I set the B measurement from center to 26. Now it’s working great!
Hope it keeps it up! Would save a lot of frustration.
Actually, you are right! So must be that the serial output is not center of tractor as I thought?
So far, so good. Can’t find much documentation or explanation on how the 2020 decides offsets, etc, but after making those changes, it is working for now.
Looking for more info around AOG to precision for gps. Getting a new to me planter with precision. My dealer said they have a serial adapter cable I could use for the connection. Sounds like it is doable but is there a pin out map available on the pin outs on the serial off of the tablet? Or did you just plug in and it worked. Thanks.
@theGtknerd setup our system for us. He wired the serial output (Tx and GND) from the roofkit directly to a four pin round like the 20/20 uses, then we didn’t need to buy the adapter cable. (The adapter cable isn’t terrible expensive, but more connections tend to mean more potential problems.)
We had some challenges common to first year startup on any new system. Sometimes it was related to solar storms or something similar where no GPS would have worked right.
Another challenge we dealt with was we were getting our correction signal from RTK2go. There were three or four base stations that were close to the max distance for us. Unfortunately, we discovered that some of the base stations went offline at random times - usually the day we needed it. So we would switch to the next base station till that one went offline. With our own base station now setup, we are hoping to get ahead of that. We are still using RTK2go. In our area, we use ATT service. I’d understand RTK2go doesn’t work for anyone using Verizon service as they get banned.
Another challenge was sometimes there was a communication issue where the 20/20 would suddenly decide we were out in the middle of the ocean. It never showed up on the AgOpen tablet, but really messed up our field acres, etc on the 20/20.
I think @theGtknerd has a pretty good idea why it was doing that. Something with if a bad message comes from the roofkit, the program should discard it. The AgOpen tablet did, but the 20/20 read it as 0.00N 0.000E which is a disaster for figuring field size, etc. You should contact him on some specifics related to that. He plans to rework the roofkit, so it discards any bad messages immediately and does not relay them. Since it really seems like a hopeless case to explain to the 20/20 folks that their product might be faulty that it can’t recognize and discard a bad message.
But in case you are getting cold feet, take heart. None of my brothers want to think of planting without guidance anymore! And we only used it one season yet.
So is the pin out for the RS232 in the picture coming off of the tablet side or from the receiving side on the 20/20 monitor?
I am not too worried about the price as the dealer we are buying the planter from happens to be the precision dealer as well and they are nice enough to offer the cable for free as they have extra just sitting around. Still waiting this week on getting an offer for trade on the our current planter but it is pretty much a done deal at this point and I am just trying to find out information now to see if I need to order anything. I have yet to see this cable but I am very curious to see if I can just plug it in or would need to create a cross over cable to adapt to it or maybe something else entirely that I may need to do.
@BaconMakesItBetter Thanks for the info and may try to reach out unless @theGtknerd happens to reply here. Sorry for all the issues you have had yourself. Curious what generation display are you working with? I only ask as maybe the newer generation works better? This one is coming with a Gen3. I heard about issues with RTK2go on here once in awhile so I built my own home base and use rtkdata.onine to host it and overall it worked well form me for last year just using the autosteer side. I am also working on building another autosteer system for a neighbor and he wanted his own base and we will probably use each other as a backup if needed so hopefully will lessen some of the possible issues around that.
Just in case it helps, @baconmakesitbetter runs a roofkit he got from me. It has serial out directly from the ESP32, but since all hardware UART ports were in use, I used SoftwareSerial which has timing glitches and bad messages on the occasion. The older Gen2 Precisions had no problem with this, but the newer Gen3 goes off in the ocean occasionally. The timing glitch is on the RS232 alone and not in the UDP transfer to AgOpen. I intend to upgrade the roofkit to not use SoftwareSerial this winter which is fast coming to an end.
rtk2data.online piggybacks off of RTK2GO
The adapter cable provided by Precision has all available configurations, you just need to figure out which 2 of the 4 plugs to use. If you are running off of the tablet you need to set up the software yet.
Is centipede different from RTK2Go? It doesn’t look like they have as much coverage in USA yet, but would that be an option for the folks that need to use Verizon service?
That is great information and appreciate the response. I am just trying to put it all together at the moment so bear with me. I have been going over the forums on what I can find so maybe I am missing some information. Are you the one doing work on the GPS_OUT project or is it a different project? It sounds like I will have problems either way but just making sure. Would be great to be able to pull this information but it kind of sounds like that might be a problem at the moment. Or maybe I will just have to work it on the bench and try it out for myself. Any other info you can provide would be great but if you are able to get it finished this winter would be great. Thanks.
The GPS_OUT app is part of AgOpen, I forget the developer. That used to have a problem that if AgOpen didn’t have a valid location it would also send a location in the ocean, but I believe that got fixed.
The problem @BaconMakesItBetter was talking about is strictly if you are using one of my dual GPS setups. If you are using an AIO, then the GPS_OUT app is what you need to use.
Ok that makes sense and thanks for the clarification. I like all of these projects that come up but sometimes it becomes confusing on what applies to what. I actually was thinking of upgrading to dual GPS on the planter this year but will probably wait to see what next year brings.
