Yeah you are right. Didnt thought about the object in the Frame. Better Let it Stay like it is right Now.

Is it possible Now in POI to degrease indegrease the Range of Circle by Flying forward/backward?
You mean flying forward / backward while doing the circle? To create a spiral?

So, the with the video streaming massively improved in the recent releases of TelloFPV, I took the the little Tello out again for the occasional fly-around to record sunsets and what not.

I use an app called ScreenRecorder to record the phone's output as well now and then. That used to work great. However, version 1.11P (or earlier?) has an odd reaction to it... an allergy? No, it's some sort of UI interference.

Here's what's happening now when ScreenRecorder is running in the background: any of the new autopilot features do no longer open the new-style dialog boxes. That also disables the gamepad controller (I can't recall if it also disabled the touchscreen controllers on the phone). The Tello hovers and nothing happens. Only when touching the respective autopilot function again, things will revert back to normal.

I have not had the time to test if that's also happening when bc DURecorder is running. Maybe others have similar experiences?

Next, another thing I noticed (this one is going back to much earlier releases) is that when the photo feature to reencode JPG files is activated, all the EXIF data is stripped out from the JPG file. Turning this off will leave the EXIF in place. So, not a big deal now that I'm aware.

Unfortunately, even then the EXIF date/time stamp isn't populated. I realize that this is a manufacturer omission, but I was wondering if in a future release the date/time stamp (that is so well-written into the file name --huge thanks for that, btw--) could be written into the EXIF tag (I think it's called original datetime or something) when reencode JPG is activated. Other EXIF tags might be populated with other useful information as well perhaps. Ed Harvey's exiftools website has an enormous wealth of information on all of that with many code samples.

Lastly, and I have to test this some more for sure, but flying circles in autopilot seemed erratic at times. Especially at lower speeds. Almost like the Tello was flying a zigzag pattern on the circle. As said, I need to test this again.

I love(!) these autopilots and could probably never have enough of them. That and the recent video fix: absolutely amazing! Thank you for that.

What is everyone's best feeling videomode settings for yaw, throttle, roll and pitch? I'm feeling 88/81/21 for all, using a PS4 controller and OnePlus6 w/ Google Cardboard in VR mode.

I totally agree with you. @volate!lo video fix works amazing. Annoying stutter dissapeared from my Tello video clips, even at low iFrames.

In my case, I let Pitch, Roll and Throttle as they were because they satisfied me.

Only axis gave me problems was Yaw. I found it extremely sensitive making Tello turns sharply. I realized when moving throttle often yaw was changed unintentionally.

I solved both issues settting Yaw Rate to 50%, Yaw Expo to 50% and Yaw Deadzone to 25%. I feel happy flying this way.

Anyway it´s a matter of personal preferences.

DURecord works fine for me. Never tried ScreenRecorder, but TelloFpv does not do anything special but just displays a couple of UI controls over a video view.

So far I haven't touched EXIF handling. When re-encoding a new image file is created from the file that was downloaded from Tello, and no EXIF information is moved over. I have moved EXIF up a bit in the todo list...

No. Almost no device offers internet access while connected to Tello's wifi so there is no inflight live stream.

I have tested a couple hours so far on 1.12 P. It seems this error is no longer happening. If I see again, I will update. This new version is great! Keep up the awesome work, I love this app for flying my Tello!

OK, thanks. I'll try DURecorder again.
The EXIF works when the re-encode JPG is off.

Oh right. I suppose one would have to have a repeater that could talk to Tello and the net.

Use a device with a SIM card? Then you have internet access over a cellular connection (3G/4G) at the same time as having a wifi connection. Read data from one and send to the other.

That solution uses a RPi which can have a wifi and a wired ethernet connection at the same time. It connects to Tello over wifi and the internet via wired ethernet.
This is nothing for the average Joe but for some IT geeks.

If it was that easy...


Seriously: As soon as you connect to Tello your cellular internet is dead. Some devices can possibly do both, but these typically don't work unless you set them into airplane mode (i.e. deactivate cellular).
To test: connect your phone to Tello's wifi, open Tello / TelloFpv app to check connection, then open your web browser and search for something that is not in your local cache.

That is because with re-encode off the file coming from Tello is just saved, and Tello creates a file containing a few Exif infos.

Yesterday four succesfull flights into TelloFPV 1.11 (I'm still not updated to 1.12)

PERFECT flights. POI autopilots are amazing. I noticed a great improvement into video quality. Not only into recorded video but also in live FPV video. Video stream recovers much quickly from interference. I feel much safer flying away or making turns.

Fom latest versions TelloFPV undoubtedly becomes the best app for flying Tello.

Congratulations @volate!lo !

Raul.

Happy to read that!

No reason to update to 1.12. From a functionality point of view it is just speed limits for the autopilots, so nothing to worry about.

Have fun!

Well, actually it is that easy.... At least when you use an iPhone!

As you know, the Tello acts as a router with an ip address of 192.168.10.1 and also acts as a DHCP server assigning ip addresses to new device connections.
So when the first device connects to the Tello it is assigned an ip address of 192.168.10.2. When this happens your cellular internet connection is disconnected.

However....on your device, if you change the Tello wifi connection settings from DHCP to Static you can pre-assign the ip address to any unused address up to 192.168.10.254.
When you then connect to the Tello in the future the same static ip address is assigned.. this is true of both iOS and Android devices.

On an iPhone you also benefit by retaining the existing 3G/4G cellular internet connection. I do not have an Android phone, so cannot comment if it works the same.
I had assumed that because you can do this manually it should also be possible to programmatically utilise two network connections.

Having said all that, I'm not sure what use you could make of that functionality!

@volate!lo Keep up the excellent work!
