Yes I know the processing is done in the controller/phone, and that it needs the signal. My whole point is, that becouse the signal is prone to break, it would make sense for Litchi to resume the mission automatically if told to do so, in case of brief signal breaks. Therefore I wouldn’t have to stop and manually restart the mission thru the app. Can the (re)starting after a signal break be done thru the custom button function “pause/resume flight”? Hopefully at least so.
This isnt under the control of Litchi, nor can Litchi override a function that is built into the drone’s design and firmware.
As for the Pause/Resume, I can only vouch for it working in Waypoint mode.
Why could Litchi not resume mission as the connection is re-established? It literally CAN, it just want’s your input to do so. So why could it not resume it automatically without your input? That would not make any sense.
At least in Litchi settings you can select pause/resume for orbit custom buttons etc. Still waiting for confirmation whether the “pause/resume” is same as “start”. Can you confirm you can initially start the (waypoint) mission with the custom button? If so, then it would make sense for the button to also start/resume the mission over again after the signal break.
I’ll try it out myself as soon as I have the chance, and will try to troubleshoot the connection issue as well as I can.
Okay, so I just tried it out. Happy to notice, the custom button “pause/resume flight” indeed does START the mission and therefore I’m able to rather easily (re)start the interrupted mission caused by signal break, after the connection is re-established. (altho the connection didn’t break as in I was seeing the preview the whole time but Litchi stopped mission because no AC position update for certain time, compared to last times “real” signal breaks where Litchi says “connection lost”, but I assume the same applies there)
So, that’s a very good news for me; this way at least I don’t need to access my phone screen and litchi’s POI settings to restart ORBIT mission. So I have only tested this with ORBIT for now, but I assume the custom button pause/resume will also start other autonomous functions. So, great.
Still I would love to have an option for automated mission (re)start after signal loss as soon as the connection is again re-established. But for now, I’m happy about the ability to (re)start the interrupted mission easily thru a physical button on RC.
Control Signal and Video Signal are 2 different signals.
Litchi doesn’t care about the video (link) signal, it doesn’t control the drone.
Yeah well as I told, ORBIT was stopped becouse Litchi didn’t receive AC position for some moments, therefore the control signal also was interrupted. But it didn’t report “signal loss” as the last time. Therefore there was a difference in the signal break, so I decided to mention it.
Are those the .CSV log files that are similar in format to what I mentioned?
Yeah I tried uploading some smaller ones to Airdata. I get to see the flight path etc there, but for those flights, the signal was good the whole time. (and I didn’t have issues whatsoever on those flights)
I don’t know why my recent logs are conciderably larger than the ones from before.
@Apa, Those logs seem huge. I hope you are finding “.csv” logs found here (I think):
Android/data/com.aryuthere.visionplus/files/flightlogs/
The beauty of Litchi’s csv logs is that you can open them as a spreadsheet on your own computer. That is, in the spreadsheet application, look for an option to “import a csv” or something like that. (they are “comma separated” csvs, if it asks)
I use “Gnumeric Spreadsheet” on a linux computer but I’d guess Excel" or whatever is current for Microsoft would do it. There’s probably a lot of other less bloated ones available for windows too.

Yeah the logs are at that folder.
@Known1, my THREE flights of that day TOTAL 35mins and those three log files total 155MB. So average of 12mins or so / flight. Especially in cold temps I bring the drone down with good % of battery left…

@Apa_Hualpa: Ah, thanks for setting me straight. Not sure why the forum moderators took issue with my post and blocked it. They claim it was “off topic”, but you ask if flying in the cold could be the cause of the issue multiple times. Anyway, moderators or not, thanks again for your reply and glad to hear you are flying safe in that crazy cold! I live in Minnesota, USA and am more than familiar with those air temperatures. That said, I have never flown in the extreme cold like you.
Happy flying and I hope you are able to provide the logs such that the people here can offer additional guidance and suggestions. If nothing else, you could always share the logs via a Google Drive link.
Props up,
Known1
@Known1 I was wondering too why it was flagged, maybe it was a bit out of line, and actually it’s not that much of a asking for trouble flying in that cold. I recommend it actually, despite my connection issues which much possibly have nothing to do with the temps, my Mini 2 performed exactly the same as always - well. Still can’t completely exclude the possibility the temps had somekind of effect tho. I’ll go fly in the coming days and do some more research. It’s not that cold anymore tho.
Surely it’s freezing for hands to control and fiddle with the drone, especially if there’s any wind. But if it’s still fine conditions, it can be beautiful and worth it. Proper clothing and Litchi autonomous functions are a convenient way to let your hands be in warm thick gloves while capturing some beauty of shots.
As far as I know, in general it’s considered that cold temps are no problem, if
a) warm batteries
b) dew point not very near the current temp
c) not flying in foggy conditions etc
d) not risking it with flying too far or otherwise letting drone battery level down as voltage may drop unexpectedly
e) can manage the cold yourself
I have a pair of handwarmer-powerbanks, which help not only with the cold hands, but in charging batteries by warming them up so they accept charge. I have only 2 Mini 2 batteries so I usually need to charge on the field.

Cold could affect physical components/connections?
Something like a cracked solder joint on an antenna?
Yes, you have a good point. You mentioned ORBIT I say Hover we understand. I have the same issues. When loses signal, while doing a Video it hovers and the Drone goes crazy in a zigzag all over the place trying to find the signal. Sometimes the video is wasted, and you will need to repeat the Mission. If the signal loss is more than I think 5 seconds it automatically does RTH as it’s been set.
Good point, something like this I was wondering myself, but some others seemed to reject the possibility the cold air could make a difference. Lately, I’ve been flying in somewhat less frickin’ cold, with less problems. The connection sometimes breaks but not nearly as easily as when it was very cold and I was flying. Go figure… Maybe if I disassembled the controller I might possibly be able to observe for apparent damages, but for anything else, I don’t have the tools nor the experience.
