New app: TelloFPV for Android

[xcrost]

Thanks for testing
#1 strange message. I noticed that Tello sometimes (no clue why) does not send position data. I will change that behaviour
#2 fixed in next release
#3 fixed in next release

Thanks for the offer but I don't need the video.

Cheers!!

Dang you're fast!

Hi there, my first post..wuhuu..

So i read the first 6 pages and the last 10 pages but didnt find the answer.
So apologies if this is asked before.

Is there anyway to use an "real" rc transmitter so the control accuracy and range would be better? Before these user made apps it was said that the controls are different between tello/bt controller and a rc transmitter, but is it possible to interpret the commands so that Tello would understand them?

Kind Regards from snowy Finland???

Unfortunately no. Some people here have gotten amazing ranges using home-made reflectors ("windsurfer antennas"): WIFI reflector for improving Tello range but the Tello can only be controlled via WiFi.

For control accuracy "RC type feel" Parrot Flypad is recommended and works with Tello FpV.

Amazing !

You are very quick fixing bugs

This forum is great. I never thought that the little Tello was going to provide me with so much fun.

all the best.

Ditto! Totally agree! Tello is a blast!

I believe the low range is only partially depends on wifi power of controller, the main reason is weak transmitter and/or small antenna inside the Tello itself. The controller may be capable of sending strong wifi signal to the drone, but what's the sense if the drone isn't capable of returning equally strong signal? Obviously it's done by manufacturer to separate Tello from more expensive drones, like Spark.
If only someone try to install bigger and more sensitive wifi antenna (e.g. from laptop) in the Tello body, - there is plenty of room there for it... Probably we'll then see 1km range.

The amazing people on this forum are working on it
Tello PCB and antenna reference, to help fellow crazy modders ;)

TelloFpv will get a revamp of all controller code, then it will support the Flysky controllers which are a new level in terms of precision. For range & better video quality you need a wifi extender.

just uploaded a build for Raul's problems.
I'm running out of pre-1.00 version numbers so this one is now 0.98x

Beside the fixes only one small feature:
* New Option: RTH can automatically descend at end of RTH (down to 1.5m)


As for progress on VR, not much unfortunately. I had a couple of other priorities, unfortunately. Starting tomorrow I'l have more time for this.

Hello ,
I'd like to greeting everyone . This is my first post on this forum . I have Tello drone and now I w'll test this application but as I have read it's more powerful and has more features than original Tello application . W'll see . Best regards Marcin

Thanks a lot !

You make me feel very important

Unfortunately I will not be able to fly and do testing until tomorrow.

You folks at TelloPilots.com are important! This is the most direct feedback I get from users.

Your soul belongs to us! Muahahahahha

Well, I remember history of one program I use. There were versions 0.9, 0.9x, 0.99RC, 0.99RC1, 099RC2... for two years, and then changelog for 1.0 stated "almost completely rewritten". "Hey, the main version number has changed, you users should have anticipated big changes", the author said.

In this case V1.0 is reserved for the VR release.

Talking about video quality...

I knows @volate!lo recomends using a 5 seconds iFrame interval, but... I disagree with him... (please, don't be angry)

When using that setting I have been experienced image corruption for long periods of about 5 seconds. That's a LONG time when flying far and it makes you sweat.

TelloFPV corrupted image improves a lot when I lowered iFrame interval. Nowadays my iFrame setting is 1 iFrame per second. Image corruption is negligible and I have not noticed any side effects.



Even I realized something curious into aTello app by @Krag. He allowed even smaller iFrame intervals, like 10 iFrames per second (don't get confuse with iframe interval 10 seconds). See here:



aTello 0.9 [Android]

What is your opinion ?

Let me invite you to make different adjust until finding your favorite iFrame value.

All the best.

[Flydrone]

I see that TelloFpV is getting better and better! As a tello pilot, I am very happy with this!
Too bad that these days I can not fly with the little drone and try once again your magnificent app. but I see that there are a lot of people flying just to test and help in improving telloFpV.
greetings from Italy.

It depends what you want to do:
The 5 sec is a recommendation for those looking to get decent video over a reasonably stable wifi link. Its a trade off.
Those pushing the limits should go for short IFrame period and lower bitrate. The further out, the lower the bitrate and iframe period.

Video quality (details like gras!) will suffer badly, but you are looking for a stable video stream and not video quality.

Consequently everyone should play with the settings to find what gives the best results for the particular use case.

You are right @volate!lo. Very good explanation.

Thanks !
