R/C over LTE - test day2 (regular usb joystick with tablet)

Sunday morning I reviewed UAV setup one again. I did`t find any additional setup for virtual joystick in Qgroundcontrol and I thought I have to contact with developers to understand why I failed yesteday. Maybe there is any additional parameter that I should enable or change before I use virtual joystick with Qgroundcontrol.

I was sure that current drone config allows me to fly without R/C. Base on that I deceided to connect USB joystick (FlySky FS-I6s in USB mode) and check drone how I can control UAV using tablet only and connected joystick.

No R/C, no PC, only joystick connected to tablet and LTE as a data link between drone and tablet.
I connected joystick to tablet morning and went to test it.

All tests are passed :) . Everything works fine, I have working telemetry link thru LTE and video digital preview, I can control drone thru LTE only. There is no additonal analog video link or unnesesery R/C parts. Everything base on LTE data link now. There is no radio receiver located on drone frame.

Of course there is one small restriction, it`s call LTE range ... but for me it`s sufficient most part of country is currently covered by LTE network. For me it like unlimited becuse I don`t think I will fly far than battery and motors allows. Additionally I do not plan to flight with altitudes over 100m so LTE datalink is fine for me.

If I find more time I will try to correct virtual joystick setup but overall I can move forward with next project phases.

Below recorded record session from Sunday tests.
