Dramatically Changing order of litchi waypoints

Mitch · May 1, 2018

I have an established mission that has to change. I have to change my launch point which in turn will change the numbering of all my waypoints. In essence my starting point will be waypoint 16 (which will be waypoint 1 after the change).

I've exported the mission from the litchi hub into a cvs file. I moved rows around in a spreadsheet putting waypoint 16 in the first position and other applicable waypoint/rows into preferred position as well. I've imported the cvs file into the hub and the mission looks fine. Then, within the Litchi iOS app adjusted applicable altitudes to adjust for a new first waypoint.

My question is, after doing this and viewing the mission within my iOS Litchi app, if the mission looks okay, am I done? Am I at risk of a bug of some sort because I exported and imported data instead of constructing the mission from start to finish within the app?

I don't want to risk a flyaway or something of that nature because I manually made changes to the data/row order outside of the litchi app.

Thanks.

With any autonomous mode you are at risk of it not working correctly, or working correctly when flying sideways into a tree, or not being able to fly against a stiff wind, etc. The first time running any waypoint mission you should be able to hit the cancel button (or switch in and out of Sport mode) if something is wrong. That means you must be able to see the Mavic at all times. Of course, you should be following this rule anyway but it is tempting to setup a Litchi waypoint mission BLOS because it is supposed to complete the mission if connection is lost. But if it doesn't, what then? Perhaps put on a GPS tracker to help find it.

Sorry about the rambling text but you did not state how far out you were going. One useful tip; make your last waypoint your home point so it should end up there if communication cannot be re-established. Regarding your actual question, I do not know. That is the main reason for my rant about keeping it in sight.
