Hi everyone,

I am running tellofpv on a Galaxy s6 I bought specifically for flying the tello. FPV mode is great with an old and cheap Xiaomi VR headset.

I am considering getting a new VR headset. Which one would you recommend? Will the Gear VR work?

BTW, are you people flying FPV mode?

Edit: would you please consider a see through phone camera option @volate!lo? It could be useful when flying FPV in order to quickly check surroundings.

Thanks

Me !

I use to fly FPV. It's much more fun ;)

I love flight inmersion and don't worry about sun glare over phone screen.

But I hate dual lens FPV googles. Due duplicate image, resolution is poor and I don't like simplified on-screen TelloFPV controls.

I always fly using a single-lens FPV googles and TelloFPV in full-screen mode. That kind of googles are very common in analog 5.8Ghz FPV model aircrafts.

I wrote a full thread talking abot this subject here:

Tello full screen Goggles for VR (Virtual Reality) or FPV (First Person View)

And my vote for your "see through phone camera option" @volate!lo request. I often lift FPV goggles a bit for returning "real world".

Interesting point of view. I think I prefer the dual lens setup though. Currently thinking of getting a Gear VR because there is a lot more one can do with it but I am not sure it would with tellofpv.

GearVR has its own closed ecosystem, just like daydream. These don't work with TelloFpv, at least not without hardware or software hacking. Really I'd get a simple Vset of VR goggles for 10-15 bucks


I can understand the "through camera" but honestly the effort is quite high. I already did a similar thing for the vGPS and spend ages getting this right.
If I do it will be only for the VR screen. There is only a small minority out there using VR FPV (abou 2% of the user base) - but the number of people doing it Raul's way is maybe 1 or 2.

The "see through" of functionality for the VR screen would be nice. And useful.

If I can bypass the app that opens when the Gear VR is connected, then it should work with Tellofpv. Is that correct?

I am quite impressed that only 2% of users of an app called TelloFPV are actually doing fpv!

You make me feel like a weirdo... ;)
Well, you make weird things :D:ROFLMAO:. Or actually not because I remember that's how it all started. But these days single screen VR is not mainstream.

All a matter of priorities... A feature that only appeals 2% of the user base and will be usefull only rarely even for those 2% does not rank very high - especially when its a lot of effrot and adds complexity.

Also FPV is not the same as VR. I FPV with the screen in my hand all the time, but rarely find the time to do proper VR FPV with controller and all that

Oops, I'am a bit late, I'm afraid :(

Yesterday succesfully tested previous 1.5b. I spent a couple of batteries outdoor despite moderate wind, coming up 150 meters away.

Video quality superb, using @volate!lo suggested values: 4 sec Iframe Interval, Skip Corrupt Frames option ON (default value).

View attachment 4521

I tried new TRAJECTORY option for DRONIE AP

View attachment 4522

User selectable options are: FLAT, LOWER, DEFAULT, HIGHER and MAX. That way, you can choose flight rise angle. Acording to my measurements, at MAX option your Tello will rise over one meter each three meters it goes away. At LOWER option it will rise one meter each twelve meters it goes away. Good news are even at MAX choice subject remains well framed at lower side of screen.

Also tested new SPIRAL option for CIRCLE AP

View attachment 4523

Values are: NO, NARROW, MEDIUM, WIDE and EXTRA WIDE. That way you can force Tello circling an object while moving away. Take into account it's a flat spiral, not a 3d helix (It will be a good idea for a future AP, dear @volate!lo). At EXTRA WIDE your Tello will double distance to object at the end of each complete turn.

A few words about generic setting screens for AP: I noticed settings values are memorized between AP flight execution except SPEED an TIMER that I have to re-enter every time during flight sesion. It would be great to have the chance to memorize our favorite values not to waste a precious battery time. On the other hand, I use to change AP values through controller sticks, values changed effortlessly but something extrange happend into CANCEL/OK line. I spent long time trying to activate OK option. Half of the time I ended up pressing accidentally CANCEL option.

I found some time to play with photo "continous mode". I can say it works although it doesn't seem useful form me ;). Bitrate is reduced to 1 Mbps and a countdown on screen informs you of remaining time until next shoot.

View attachment 4525

By the way, a mistyping at photo settings screen: "autotart"

View attachment 4526

I hope it helps. Best regards

Raul.
Raul, great! You are right, I missed that one!

I will look into memorizing timer setting of different APs between runs, actually I thought it would memorize already.
Speeds are different speeds depending on the AP, so I don't think it's that useful here. Dronie speed simply has a different meaning then 360 speed.

I will look into the cancel / OK problem

Thanks for testing!

I also fly mostly VR FPV ;) and have been patiently waiting for the "outside" view feature since the start of this thread. I was hoping you could use the vGPS calibration while in VR for both of these features? The camera would have to activate regardless of distance/height and just display a message "Tello to close etc. for vGPS calib.". Seems like the basic function is there?? I am not a programmer :(

Hello Tello friends,

also I love the VR flight with TelloFPV. V. 1.5c is TOP, no errors noticed.
I'm looking for a quiet place, put the Wifi-repeater on the car roof and I sit comfortably in the car to fly, takeoff and landing on the hood.

Thanks volate!lo for this enrichment.

Idea:
Volate!Io, great when the GameSir T1s the electromagnets in the grip would vibrate briefly on battery warning.


best regards

Doesn't work, because TelloFpv does not chat directly with the controller. It just receives events from Android indicating some stick was moved - but there is no way to send commands to the controller

TelloFPV 1.5c tested yesterday. Excellent video, range and control. No flight issues at all, but...

I shooted a Photo Pano 360 and got TWO file folders into my android device: "Pano 360 2019-09-03 17-07-17" and "Pano 360 2019-09-03 17-07-17 level". I'm sure "Rotate and Crop to Level" photo setting is OFF.

Raul.

So you got even more than you asked for !
I will check, could be a result of re-arranging the settings.

By the way, I noticed AP screens reworked:

tellofpv spiral abreviature.jpg

Spiral options has been abbreviated to single letter "M", "S" and so on.

I noticed "Speed" and "Timer" settings are now memorized between AP executions. Congrats @volate!lo !

It seems to me OK/CANCEL buttons works better now. Maybe it's just a feeling :unsure:

Cheers.

Got a chance to fly and test some AP's. Excellent! as usual! One thing, on circle POI (pictured above) when in VR, the left pupil value does not change for spiral and ...timer I think. Maybe some other AP's too. Thanks Volate!lo!

I think you reported that one before and I thought that was already fixed. I will check that for the next release

@volate!lo,

I can confirm you during yesterday flight session "Level" folder was created again. As said, I'm sure "Rotate and Crop to Level" photo setting is OFF. It's curious than non-level folder has five shoots but level folder only has four ones.

Cheers.
