Section Control Line Jumps

Hi,
I’ve got a slight problem with section control. While driving at a constant speed, the green line wich indicates the switching on point for section control jumps closer to the tractor for a short time, maybe every 30s or so for half a second. This results in poor coverage, because in those cases the sections get switched on too late.

My Setup: Benjamin Dual, F9P with code by Franz Husch, AOG v6.7.1 and Rate Control for SC
I created a log a while back where it became clear that some messages from the Dual esp32 got send multiple times. Franz explained to me that that happens when there are missing messages from the f9p’s, he also tried to provide new code, but that didnt help.

Has someone experienced the same an has a solution for me?

Greeting Bennet

Have to checked that you use firmware 1.13 and only 3 constellation?

Other setups can lead to missing sentences.

The displayed speed is constant?
Forward speed?
How many seconds of look ahead?

yes, I use 1.13. What do you mean by only 3 constellation?

Displayed speed in the AOG main screen is constant.
Forward speed? How fast I am going?
On time for the sections is 4 seconds for my sprayer, 1.5 sec for the planter.
