I did some investigating on this RTH with Litchi. I also contacted Litchi and kind of got the same answer as you did. From a few other forums and some digging around, it seems that DJI have embedded into the firmware this "Smart" RTH feature. It is in the Go app if you look. A lot of misconception about how it actually works. But most agree, that if it is toggled "ON" in the Go app, it is like some of the other features such as "EXP, GAIN, and a couple other things" it writes this information to your aircraft, and it is stored there. The "Smart" RTH monitors the battery and determines how far away you are and will force the phantom to abort your Litchi waypoint mission, or any other type flight whether it be Litchi or Go app. If you turn it "Off", it does not disable the normal RTH for low battery or signal loss. In my situation I explained earlier when I tried the missiont with my Galaxy S5, I didn't realize the I had this option turned "Off" in the Go app. I re-ran the previous flight I was experiencing the RTH with a Litchi mission, same tablet, etc., but turned "Off" the smart RTH in the Go app before I switched to Litchi.......worked perfectly like it was intended. Don't know if this will help anyone else, but it was the "FIX" for me. The particular flight I had issues with is one of my longest ones, around 5-miles total distance, but the phantom must think it is a bit too far for it to make it back home, but I make it back every time with at least 30% battery left. I'm leaving it turned off in the Go app.
It wasn't really an issue, but was the only time I experienced the RTH with Litchi mission. More of a challenge to figure out I guess. I have used the Litchi mission to go some places that left me without a signal for 10 minutes , and it always returns with amazing footage. I do take the time to investigate the flight path, altitude, etc. But it allows me to go around corners, over bluffs and such that I would for sure lose signal and have a RTH without using Litchi. It is a very powerful tool as far as I am concerned. The first few times you do this though is very tough on the nerves. seems like an eternity waiting for it to return! But at this point I have done it enough that I have full confidence it will come home. Happy flying.
Thank You, RicardoGray! |
