I need help: How to connect my EV800DM Goggles to my Drone?

[cosmic forge]

I accidentally reset my drone. I bought the Eachine Novice IV set at the time because everything was set up and ready to fly on arrival. However, I accidentally reset the drone in Betaflight and now I can't get my EV800DM goggles to connect, so I can't get a picture. Does anyone know how to fix this problem?

You will need to set up the Video Transmitter (VTX) settings, see the guide on the VTX tab. Also, since you've reset the drone, you may also need to set up your channels again, which is done on the Receiver tab. For more assistance, please visit the help and support forum at #1052457584772255784.

[cosmic forge]

I did

[carmine pumice]

now, with the lipo still plugged in into the drone, go into the vtx tab in betaflight configurator, and post screenshot of the right-most section..

Device Ready: true (green)

[carmine pumice]

now, on the left section of this tab, set it to a channel (band and channel)

preferably to one that's already set on your goggles

or set your goggles to the exact same channel

e.g. R8

(Race Band, Channel 8 = 5917MHz)

[cosmic forge]

Ok i did

[carmine pumice]

are you seeing something in the goggles now?

[cosmic forge]

No

[carmine pumice]

can you set the power in the VTX tab to something like 25mW

(25)

don't forget to save

[cosmic forge]

I see RF 8 below CH-A-4 and 5805M

[carmine pumice]

so your goggles is not on raceband 8

it's on A Band channel 4

[cosmic forge]

I can change it

[carmine pumice]

which I already asked earlier

[cosmic forge]

Oh haha sorry

[carmine pumice]

refer back to the user manual I have posted earlier on how to change channels if you don't know how to yet

[cosmic forge]

I know how to change them

[carmine pumice]

can you post another screenshot of the right-most section in the vtx tab please

[carmine pumice]

are you seeing something in the goggles now?

[cosmic forge]

Yes damn

Nice thanks

[carmine pumice]

now, set up your OSD in the OSD tab

make sure at least Warning is active and it can easily be seen in the goggles..

e.g. set it either at the top center or bottom center.. so you can easily see what they say

[cosmic forge]

Ok i did

[carmine pumice]

now, still without props, go into the motor tab..

enable the "I understand the risk"
(read it and understand what it says)

[cosmic forge]

yes

[carmine pumice]

then use the master slider in the right side, drag it slowly up and see whether the motors spin

[cosmic forge]

they do

[carmine pumice]

then disable it..
unplug from usb, reboot the drone (unplug-replug the lipo)

and try to arm, with your goggles on your face so you can see what arming disabled flag will come up

this drone has a GPS

[cosmic forge]

I can see everything but it only beepswhen I want to arm the drone

[cosmic forge]

yes

[carmine pumice]

if it is enabled, then you need GPS satellite lock.. at least 8 satellites.. per the manual

[cosmic forge]

Yes i know

[carmine pumice]

can you post a screenshot on how you've set up the OSD tab please

[carmine pumice]

then it will not arm without 8 satellites..

take it outside and wait for those 8 satellites

[cosmic forge]

I was not shown anything of what I had set

[carmine pumice]

then set this to NTSC

or you will have to reflash your flight controller so that OSD(Digital) is not selected in the options

before you reflash, save another config backup so you can reapply this later after flashing

use the Preset Tab this time..

(there's a Save Backup button in the Preset Tab)

[cosmic forge]

Ok where can i do this

[cosmic forge]

Ok reflashed

[carmine pumice]

reapply the backup you made via the same preset tab..

there's a Load Backup button

[cosmic forge]

I did now i can see everything

[carmine pumice]

now, unplug from usb if you haven't yet.
take it outside and wait for 8 satellite locks..
once it's got at least 8, try arming

[cosmic forge]

Ok

i can't get a connection to satellites

[carmine pumice]

how so? are you under a rock?

[cosmic forge]

I was outside on the balcony but in the glasses it said 0 satelitten all the time, the GPS works but about in Betaflight

[carmine pumice]

on the top, in betaflight, in the row of sensors, is the GPS icon red?

[cosmic forge]

if you mean 3D Position yes

GPS in general no

[cosmic forge]

Oh this

[carmine pumice]

is the GPS icon red in this row?

[cosmic forge]

Yes GPS is red

[carmine pumice]

then this will be a temporary work around: you will need to set it back to how it was after testing:

go into the Failsafe tab

(in betaflight configurator)

[cosmic forge]

yes

[carmine pumice]

enable this

[cosmic forge]

Ok

[carmine pumice]

of course, save and reboot

unplug from usb
replug lipo
and try arming..

see what other flags would show up in the goggles if it still doesn't arm

[cosmic forge]

it worked

[carmine pumice]

motors spin?

[cosmic forge]

yes and reacts to the throttles

[carmine pumice]

now, disarm. unplug lipo.. put in the props, correctly..

and arm it and try to hover.. (slowly ramp the throttle up.. slowly)

if it doesn't spaz out, or it doesn't tumble and actually hovers, you're kinda set

feel free to disable the "Allow arming without fix"

[cosmic forge]

All right, I'll try it tomorrow, I have to go to football training now. But thank you so much for your detailed help and time, I would never have managed it like this!

[carmine pumice]

and thank you for being cooperative and not going into your own and actually following instructions

thank you for trusting in me

[cosmic forge]

Hello, I have tested the drone. The problem with the satellites has been solved, so I can see enough now. However, it felt like I only raised the throttle a millimeter and the drone quickly turned upside down to the right.
