I’ve yet to upload all my data to AirData … whilst I’m trying to decide exactly how to use because of their 100 flight limit for the free version.
All my flights up to 6th June 2017 have battery temp data - all three batteries.
Then there’s a gap in the data uploaded (although I do have that data) until 24th November, and no battery temp data is recorded/showing after that.
24th November is soon after my MP had been on a quick trip back to DJI to check the gimbal (when they quoted £££ to fix everything but the gimbal, even when there was nothing wrong with that everything else, anyway).
Just prior to sending it to DJI, I did update the firmware to whatever was the then current official version.
Anyone else with this experience?
I did notice that @PingSpike’s MP entry also had 0°C.
Spent some more time looking for patterns today, still can’t see one.
I thought I’d spotted an issue on short flights (less than 5 mins) but then I found a couple of +20min flights with no temp, and a couple of 4min flights with battery temp data. So it’s not that either…
Drilling down in to the detailed battery data of each flight, the correct ones look like this:
Interestingly, I’ve been going back to the app version theory for this too.
Every single flight using an unmodified GO4 app does have battery temp data.
ALL my historic iOS flights have temp data (before I got a CS last year).
Then my logs show a clear move to Android and running GO4 4.1.6 on the CS, unmoddded, all has temps too.
As does 4.1.14 (I guess I did a CS firmware update in mid-november 2017)
Then in April 2018 when I started using my modified GO4 app of 4.1.22 - this was the first time I saw flight data with no battery temps. Too much of a coincidence?
From that date onwards I’ve only ever flown 4.1.22 modded - and it clearly has very mixed results in terms of battery temp data.
I’ve emailed Airdata support.
I’ll also give the devs on slack a shout to see if this is a known issue.
Be interested to know what Android version of GO4 you’re running Dave, and if your pattern of version numbers matches my gaps?
I’ve never used Modded Go4 - so I can rule that out.
Mine totally stopped some time before last Novermber, and I didn’t tinker with firmware until this Feb time. So we can rule out modded firmware.
INTERESTING … that you mention “I guess I did a CS firmware update in mid-november 2017”, and it’s then that mine stopped.
As I said at the top, this isn’t long after I got my MP back from DJI, and I’d done an firmware update … THAT HAD A BATTERY UPDATE (one of my batteries bricked and DJI replaced it) … the day before it went back … 5th September '17 … to whatever the version was then. Prior to that I’d never done an update.
I’m up to my 100 free entries on AirData, and not made my mind up about how I want to use going forward … so there’s a gap in what I’ve uploaded between June and Nov 17. I do have the missing ones, so might have to upload to determine when it actually stopped.
Good that you have a paid sub to AirData … they are more obliged to respond.
I uploaded a flight without temps to the PhantomHelp viewer, and downloaded the csv … but no battery temp info, only voltages.
It would be useful to know if that data is missing from the file or if it’s AirData’s conversion, for some reason.
So it looks like the raw log file doesn’t contain the temp data then? Hence airdata.com can’t display it either.
Hmmmm… My first flight with no temp wasn’t until 1st April 18
And I’ve been running .700 on the Mavic since November, and every flight on .700 up until April has had temp data. I’ve not changed any parameters or anything else, until the app version change to the modded version, which I did in April. Too much of a coincidence still!
Ummm - I read that as PhantomHelp viewer doesn’t extract that info … there wasn’t a column of zeros. There’s lots it doesn’t display.
Give me 5 I’ll upload one to there that does have temp data and double check they’re not deleting columns without info.
I might rip out al my AirData data and start again … but concentrate on the period from having temps to not having temps (June/Nov '17) … and see if it all goes wrong on that Sept 5th.
That’s the last time I can recall a battery update being applied.
Edit: Thank goodness for local backups! Thank devilness for my totally disorganised local backups!
Ha! Something else that changed at some time ….
Going back to a Sept 17 backup of my phone, the app used to have the .txt files AND the .DAT files downloaded! Not any more!
Bums!
