Has anybody used or know where the documentation is which explains the use of "Split into x segments" on the simple grid mission plan?

Using MP 1.3.35.

Thanks in advance.

have you tried it?

i think i may need to look at ti again givben some recent changes.

but it adds rtl's inside the mission, so you could come back and land, and then resume where you left off.

I did.

Landed, swapped the batt, started up in stab, transitioned to loiter, then auto, which it them proceeded to WP1 and began all over again.

Did this twice, both times going to auto, mission started over again at WP1.

Is there any documentation on the feature and the way it is supposed to work?

i think i will need to revisit this function. it did workm but seems to be problimatic atm.

where you testing with plane or copter?

Copter.

So, currently no documentation then?

currently no, i made modifications yesterday to it. but currently you still need to define the starting point

Not clear on what you mean by defining the start point.  Here is what I do;

1.  Polygon, Simple Grid, Split into 3 segments, Accept

2.  There are additional WP's in the lower dialogue box, with RTL's and Takeoff's.

3.  Write mission

4.  Take off and switch to Auto

5.  Hits the RTL WP, and lands

6.  Swap battery, launch in Stab, switch to Auto

7.  Mission/flight begins again at WP1.

How am I to define the starting point noted in your earlier comment?

Maybe this feature is not usable at this time?

Thanks again!

you need to manual set the start point for the mission after the first battery.
ie if the last rtl was at point 30, you would need to manualy set the wp to 31.

you can do this on flightdata from the actions tab.

Hi Michael, but in mission plan splited, there is already take-off command,  In my example: As others-restarting couses start mission from the very begining.

Hello,

I am having the same problem. I proceed just as Tim V's workflow, and the droid flies to WP 1 after battery swap.

I have tried both while powering droid via USB during battery swap for uninterrupted current, and performing battery swap without auxiliary power (powerdown). I am flying an IRIS+, using MP 1.3.41 build 1.1.6110.31287

Thanks!

Since this discussion is still relevant, here are my observations:

1. Split into 'X' segments does not perform as one would expect, given the interface/wording within mission planner and the creation of waypoints.

2. With 2 iris+'s, and two other quadcopters using pixhawks, my experience has been exactly what is stated in this discussion: After the first RTL and battery switch, when the drone takes off and is switched to auto mode, it will go for waypoint 1, and not the first waypoint of the second section.

Given that MP will insert a takeoff and a landing waypoint at the start and end of each segment, my process has been a simple workaround. I select all waypoints for the first section that was just completed, delete the waypoints from the plan so that the new waypoint 1 is the takeoff waypoint for the second section, and then I write the mission to the pixhawk. 

This is not an elegant solution, but it is not clear to me from the MP documentation that the flown sections are meant to be remembered and the next section automatically flown. From what I can tell, the current segment behavior is the intended segment behavior, and the solution of removing the previously flown waypoints is the required, best, or comparable to the best solution, given the application's current design.

I hope this helps, for anyone doing flight segments

EDIT: I always save my survey grids, so that I can reuse them in the future. This is useful when doing segments, since you will be deleting the waypoints as each segment completes. If you want to use those same deleted waypoints again, just reload your saved grid. 

Perfect Andy, yours is actually the most simple workable solution for breaking plan segments, especially after saving the initial survey we can recall anytime the deleted WPs for the future missions on the same field. Thanks a ton.
