New app: TelloFPV for Android

Por favor, intente con esta aplicación:
https://play.google.com/store/apps/details?id=ru.elron.gamepadtester&hl=en_US

Si los sticks se reportan como AXIS X, Y, Z, RZ (en cualquier orden), entonces funcionará. Es posible que las asignaciones de botones no funcionen (aún), pero lo harán pronto.



please try with this app:
https://play.google.com/store/apps/details?id=ru.elron.gamepadtester&hl=en_US

If the sticks are reported as AXIS X, Y, Z, RZ (in any order) then it will work. Button mappings may not work (yet) but will soon.

[QUOTE = "Ansia, post: 16554, member: 3533"] En teoria, se supone que funciona. Yo no tengo los servicios de Wii, pero no tengo Cambiar para probar. En realidad depende del celular. Si lo logras emparejar, funcionará. [/ QUOTE]

Logro coincidir con el control y la APPlo reconoció, pero cuando quiero controlar el avión no tripulado, la respuesta es demasiado lenta ...

Vuela al menos 2m de altitud y usa el Sportmode. Pruebe la yaw (rotación) ya que le da la mejor idea sobre el retraso del controlador. Todos los demás ejes están filtrados por tello.
 
[QUOTE = "volate! Lo, post: 16565, miembro: 4528"] Vuela al menos 2m de altitud y usa el Sportmode. ¿Qué es el retraso del controlador? Todos los demás ejes están filtrados por teléfono. [/ QUOTE]

Me refiero al tiempo de respuesta desde que muevo la palanca de control del controlador profesional hasta que el drone responde ...??‍♂
 
emmm....

Maybe we should make an effort using only english into this forum.

google translator is our friend ;)

imagine each one speaking their own languaje, russian, chinesse ...

(my spanish is perfect but my english bad)

raul.

[QUOTE = "Ansia, post: 16566, miembro: 3533"] Esto es normal. El control del interruptor no está optimizado para los androides. La mejor manera de eliminar el retraso del comando, es conectarlo por OTG. Me pasó lo mismo con el control de PS4. [/ QUOTE]

Al mediodía trataré de decirles.

[QUOTE = "JNazaret, post: 16570, member: 5678"] [QUOTE = "volate! Lo, post: 16565, member: 4528"] Fly at least 2m altitude and use the Sportmode. What is the controller delay? All other axes are filtered by telephone. [/ QUOTE]

I mean the response time since I move the control lever of the professional controller until the drone responds ... ??♂ [/ QUOTE]

How is the response time in the gamepad tester?
 
His problem is a bluetooth issue. He will not be able to fix it, since it wasn't optimized for Android.
I don't know these controllers. If they have such a bad lag then it won't work, but often people report "lag" when in fact they try videomode in 0.5m altitude, which means Tello is totally sluggish regardless of the controller.
 
v0.98y is out for beta test


New features
------------
* Arm Motors can be mapped to controller button
* Temperature threshold for overheat warning
* RTH will not switch from sportmode into videomode (risk of driftaway in strong winds)


Fixed issues
------------
Potential loss of control over drone after controller disconnect
Controller Tuning now shows current stick position in both modes



@tello_ar
I hope I found the bug, but I am not 100% sure because I can't reproduce the problem. You said you experienced these problems on every 4-5 flight. I have never experienced this which puzzles me. It seems that it is somehow related to your pre-flight routine.
Do you use settings screens before each takeoff? In some particular order? Do you leave the app after connecting the drone, or the controllers? Anything else that goes beyond " start app and fly"?

@all: please let me know asap if you experience similar issues in v0.98y. this has to be fixed!
 
Btw, earlier, she fell out of the sky. Stopped mid-flight... Down like a rock.
I had used a WiFi utility (WiFi manager) in the past on my phone, which I since removed... Only had short amount of time, but thought it was better thereafter. Can't say for sure.
Looking for a better wired controller now too. Hopefully soon I'll have my dedicated Galaxy S7 active ready so i can ONLY run TelloFPV and some select necessary apps and nothing else that might interfere.

I have now read about 3 "drops like a stone" events. Wifi utility or whatever can not be the cause. Nothing an app can can cause Tello to shut off midflight.
They seem to have some problem in the firmware. Luckily I only upgrade one of my Tellos to latest firmware, the others stay as They are.

OK, so here some first results flying 0.98y!

I ran through all of my 7 batteries and experienced not a single issue!

Currently I get a little less flight time out of each battery as I've mounted a Hawkey Firefly Micro cam (ugly1080p, don't bother), about 15g extra weight, plus I installed stronger rotor guards that actually let you 'lean into' a wall w/o going down! Highly recommended.) Take-off weight currently 106g with battery (charged that is, --yup). But it flew absolutely great throughout, loaded like this. All in all, I flew it a bit over 50 minutes indoors (dark, sleet/snow outside).

In the past, I would've had a run-away, I'd say, at least once, or maybe twice, pretty reliably during that amount of flight time. Not this go-around! (Whew... --regaining confidence!)

Please note, this is also after removing the third-party WiFi helper app from my phone. Maybe it interfered somehow. I also calibrated the Tello using the orig.Tello app. Decidedly better at hovering now. But that's not related to the run-away problem. That it dropped 'out of the sky', was a bit of a downer... but, hopefully a fluke; or so exceptionally rare that I it's not worth worrying about too much for the time being.

So, I took some notes what I've been doing pre-flight:
  • Check rotors, flick rotors to check if they move freely, rotor guards, so that all clears, esp. after crashes
  • Disconnect/Force Stop NordVPN (VPN app, which will not allow Wifi connection to drone)
  • Check/Force Stop orig Tello app
  • Check/Force Stop TelloFPV (to assure that there aren't two instance running, ever)
  • Set screen rotation to Auto
  • Set Airplane Mode ON
  • Set WiFi ON
  • Clear All Apps using Android button (square one on bottom of Android 8.0 screen)
  • Plug in WiFi amp, check that active (yellow light)
  • Turn on Gamesir T1s using home button +"A" (which activates the blinking red mouse button light later when connected)
  • Plug in "Cable Creations" OTG cable (LG G6 to Gamesir T1s)
  • Put in fresh battery into Tello, turn on Tello, watch Tello LED for color modes
  • Wait for Tello to establish a connection to Wifi Amp (Xiaomi Mi 2), blue light on
  • Open TelloFPV and click TelloFPV icon for WiFi to enter phone's WiFi settings
  • Select the WiFi from WiFi Amp, wait, when prompted click OK to affirm that there's no internet connection
  • Return to TelloFPV app, wait for video stream, check notifications, if applicable
  • Arm Motors, and if all sounds good, manually take off
  • Crash
  • Start it all over.
I had the app crash hard a couple of times after I upgraded and while trying to connect for the first time in 0.98y to the Gamesir. I've been trying as hard as I could now to reproduce this, but I can't (that's good). The only time the app disappears, is when I long-press the Gamesir 'home' button and the 'Y' button simultaneously. Then the app goes into the background, but is still open. So, who cares. Pulling the OTG cable also leaves TelloFPV unfazed. If I smash the phone with a hammer, the app is still running too (somewhere, --just not on my phone!)
No clue what might have been going on there initially...

I noticed I can arm the motors now with the sticks (lower-right/lower-left) much more easily than before. Nice!
I tried, and totally loved, the feature of mapping a controller button to arm the motors! Awesome.

Here's an idea (totally useless, but it's strictly from a software elegance of design flow perspective only, ...those little neat details... it's just a thought, seriously):
If I press the mapped 'arm motors' button again (I re-mapped the 'Start' button) while the motors are idling (not yet flying!), the same dialog box pops up, again asking if I want to arm the motors... I assume the Tello knows that the motors are running and it is probably reporting back to the TelloFPV app that this is going on (I don't know, I simply assume). IF that's the case, then a different dialog box could ask the user if the app should shut down the currently idling motors, i.e. send a 'left stick down 2 seconds' command). Pressing the mapped button mid-flight should suppress any dialog, because it doesn't make sense then to display a dialog box to arm/disarm motors.

Anyway, thank you very much for this upgrade!

I just thought if i can use android gaming device like this with TelloFPV.

OK; lets hope that was the root cause.

I can see crash stacktraces for 0.98y for a phone called LGUS997 running Android 8.0. The TelloFpv device id (see "menu about") ends with 2a98 . Is that yours?
The crashes happened when opening a settings screen guess?
