VTX Admin and backpack does not work | ExpressLRS Community | Page 1

#

How did you flash? Did you set the jumpers on the TX modules back to normal operation? Have you updated the backpack firmware?

#

Do you have SmartAudio/Tramp configured properly on your FC? Does the Betaflight VTX tab report "Ready" when you have a battery plugged in?

#

Well as I wrote - backpack wifi doesn't appear on module, I flashed 1.1.0 backpack firmware via UART. I did switch dip switches from 1,2 to 3,4 before flash, did push 82GPIO then 82RST, released RST then GPIO, it flashed sucessfully.

#

But still no backpack wifi or functions work

#

Smart audio works correctly, it's "Ready"

#

And i did put dip switches back into normal 1,2 position after flash

hot void Nov 4, 2022, 5:34 PM

#

If SmartAudio is working properly then you should be able to change channels on the VTX at least, as the backpack isn't used at all

#

What Telemetry ratio are you using?

1:64

hot void Nov 4, 2022, 5:35 PM

#

Are you making changes with the arm switch disarmed?

hexed mortar Nov 4, 2022, 5:35 PM

#

yup

#

hot void Nov 4, 2022, 5:36 PM

#

Can you change VTX channels from the BF OSD menu?

hexed mortar Nov 4, 2022, 5:38 PM

#

yes, just tested it

#

on two of my drones

hot void Nov 4, 2022, 5:39 PM

#

Then VTX admin should at least be able to change channels

#

Can you show a photo of the receiver wiring to the FC and a CLI dump from one of them?

hexed mortar Nov 4, 2022, 5:41 PM

#

you mean from drone?

hot void Nov 4, 2022, 5:41 PM

#

Yes

hexed mortar Nov 4, 2022, 5:43 PM

#

I won't be able to show you wiring, but I flew these two drones today after flash, RX side works

#

I have 6 drones and all of them have working smartaudio and they connect to the reciever and can fly normally

hot void Nov 4, 2022, 5:44 PM

#

You don't have them wired to an SBUS pad? You have them wired to a full UART and are getting more than 10 telemetry sensors?

hexed mortar Nov 4, 2022, 5:47 PM

#

They are on full UART. Stacks are different. Will check sensors in a sec

#

sorry it's sideways

#

10 sensors on happymodel EP1

hot void Nov 4, 2022, 5:56 PM

#

Then something is wrong with your wiring or Betaflight configuration

#

Do you have Telemetry enabled in Betaflight?

hexed mortar Nov 4, 2022, 5:57 PM

#

how come the wiring is bad if my drones are flying for year now and i can flash RXs via bf passtrhough 😄

hot void Nov 4, 2022, 5:58 PM

#

Wiring or configuration

#

RC commands are only one way

#

There is no communication from the FC back to the receiver right now, probably a configuration issue

#

Make sure Telemetry is enabled in Betaflight

hexed mortar Nov 4, 2022, 5:59 PM

#

#

no issues there

hot void Nov 4, 2022, 5:59 PM

#

Can you post a CLI dump?

#

Something isn't adding up

hexed mortar Nov 4, 2022, 6:01 PM

#

Well i don't think it's problem on RX side my man

hot void Nov 4, 2022, 6:01 PM

#

If you have Telemetry enabled and can flash via Passthrough you should have more than 10 sensors reported on the radio

#

But you are not

hexed mortar Nov 4, 2022, 6:01 PM

#

I do have more than 10 if that particular drone has GPS and Baro

hot void Nov 4, 2022, 6:02 PM

#

Can you post a CLI dump and photos?

#

Even bare bones has accelerometer stats, flight mode, etc

#

Can you also load the webui page for one of the TX to make sure they were flashed with the correct options?

hexed mortar Nov 4, 2022, 6:08 PM

#

I really don't think it's problem with all 6 of my drones -- I wrote in original post that even VRX backpack does not react, there is no TX backpack wifi when I enable it in LUA. But VRX side seems to be working because I did flash that one via its own wifi sucessfully. RXs do work, they can enable their own wifi, they can be flashed via passthrough.

#

If i check TX page, there is version 3.0.1

#

I cannot check version of backpack TX since its wifi doesn't come up

hot void Nov 4, 2022, 6:09 PM

#

The backpack has nothing to do with changing channels on the VTX. Something is wrong between the VTX and your transmitter, we're trying to figure out what that is first

#

Please load the webui of the TX module and take a screenshot

hexed mortar Nov 4, 2022, 6:10 PM

#

And how does the VRX switch channels?

hot void Nov 4, 2022, 6:10 PM

#

VRX requires the backpack to change channels

#

But the first half isn't working now, so the second half definitely won't work

hexed mortar Nov 4, 2022, 6:11 PM

#

I see

hot void Nov 4, 2022, 6:11 PM

#

We need to get the TX -> VTX side working first

hexed mortar Nov 4, 2022, 6:11 PM

#

will send screen in a sec

hot void Nov 4, 2022, 6:11 PM

#

Then we can troubleshoot the TX -> VRX if it still isn't working after we solve the VTX issue

hexed mortar Nov 4, 2022, 6:18 PM

hot void Nov 4, 2022, 6:22 PM

#

What radio firmware are you running? eg EdgeTX 2.7.1

#

Can you show the external rf sections of your model setup page?

#

!externalrf

wanton rampartBOT Nov 4, 2022, 6:22 PM

#

The following image shows ideal settings for external RF

hexed mortar Nov 4, 2022, 6:25 PM

#

I have Mambo, still waiting for EdgeTX 😦 It's running FreedomTX 1.3.4

#

which is the latest one

#

I'm missing the Baudrate and Status options, I have CRSF CH1-16

#

And ModelMatch 00 but I gues that has nothing to do with this

hot void Nov 4, 2022, 6:28 PM

#

I'm trying to remember if there is anything weird about the Mambo related to this, but I don't think there is

#

Can you show a clear photo of the wiring and a BF CLI dump?

hexed mortar Nov 4, 2022, 6:34 PM

#

This is for Apex 5" , Mamba F405 Mk2 stack, BetaFPV 2,4G Nano reciever connected to UART6

hot void Nov 4, 2022, 6:37 PM

#

Can you post a full dump and a photo of the wiring?

hexed mortar Nov 4, 2022, 6:38 PM

#

diff all isn't full dump?

hot void Nov 4, 2022, 6:39 PM

#

No dump is dump, diff is diff

#

What ESC do you have? If BlHeli32, make sure the RX6 wire isn't connected in the ESC plug

hexed mortar Nov 4, 2022, 6:41 PM

#

No its Mamba F40 BlheliS

#

no telemetry

hot void Nov 4, 2022, 6:41 PM

#

Can you show the ESC connector?

hexed mortar Nov 4, 2022, 6:42 PM

#

But wait, i have the same issue over 6 different quads

#

different stacks and RXs

#

none of them can switch channel

hot void Nov 4, 2022, 6:43 PM

#

Let's fully troubleshoot one then figure out if all have the same issue

#

CLI dump and photo of the ESC connector please

hexed mortar Nov 4, 2022, 6:44 PM

#

i sent u dump already with the rx wiring photo

hot void Nov 4, 2022, 6:49 PM

#

Sorry, just saw the dump. Can you also show a picture of the ESC connector?

hexed mortar Nov 4, 2022, 6:50 PM

#

hot void Nov 4, 2022, 6:50 PM

#

Where does this wire go?

#

Sorry, the blue not the red

hexed mortar Nov 4, 2022, 6:51 PM

#

To ESC, there the exact same connecor on ESC

hot void Nov 4, 2022, 6:51 PM

#

Remove that wire

hexed mortar Nov 4, 2022, 6:51 PM

#

Its glued in 😦

#

I can disconnect whole esc

hot void Nov 4, 2022, 6:52 PM

#

Then your FC won't get power

hexed mortar Nov 4, 2022, 6:53 PM

#

Ah, true that 😄

#

well.. cutting it is

hot void Nov 4, 2022, 6:54 PM

#

Can you try reflashing the TX module quickly

#

Maybe via USB instead of WiFi

#

And the RX via passthrough

#

If that's the issue I would expect problems with the RC link as well, which it doesn't seem like you have

#

I don't see any other problems with the BF config or wiring

hexed mortar Nov 4, 2022, 6:57 PM

#

Too late, scissors were faster 😄 I too do wonder if RX6 from esc can mess up RX comms on UART6

#

If this doesn't help, I will try to flash TX via UART

#

Well.. did cut the blue wire and it did nothing. Still 10 sensors and cannot switch VTX channels

#

I'm going to flash TX via UART, do I need to do the GPIO-RST button dance for it too?

hot void Nov 4, 2022, 7:13 PM

#

You shouldn't need to, only if it won't go into bootloader mode by itself for some reason

hexed mortar Nov 4, 2022, 7:24 PM

#

So I reflashed ES24TX Pro with UART and EP2 RX with Passthrough using 1.5.2 configurator, Success - no errors

#

nothing changed

hot void Nov 4, 2022, 7:29 PM

#

Can you load the WiFi config page for the receiver?

hexed mortar Nov 4, 2022, 7:39 PM

#

hot void Nov 4, 2022, 7:41 PM

#

This is a different receiver

#

Can you show the page for the BetaFPV Nano we've been working on?

hexed mortar Nov 4, 2022, 7:44 PM

#

#

other tabs are the same

hot void Nov 4, 2022, 7:45 PM

#

I'm running out of ideas here

#

Do you have another FC besides the Mamba we can look at?

#

What is the EP1/2 on?

hexed mortar Nov 4, 2022, 7:46 PM

#

I'm thinking about flashing it back to 2.5.1 to see if it works

hot void Nov 4, 2022, 7:46 PM

#

Yes, that's a good idea

hexed mortar Nov 4, 2022, 7:47 PM

#

EP2 is on HGLRC F722 stack

#

Oh sorry its EP1 but it's the same as 2

#

So 2.5.1 didn't help either, same problem here

#

I did flash both RX, TX and used V2 lua

#

I can try to downgrade the backpack firmware too

#

1.0.0 backpack has problems compiling for change 😄 I will leave it on 1.1.0 ... I'm out of ideas

grand halo Nov 5, 2022, 12:37 AM

#

If you are only getting 10 sensors via telemetry then betaflight telemetry is not working. If it was then you would see 18 sensors. And on them you should see yaw/pitch/roll angles in radians and they will update when you move the quad around.

hexed mortar Nov 5, 2022, 7:44 AM

#

Well I said to myself let's sleep on it and it did help. I noticed that most of my 868MHz quads do have 18 sensors in telemetry. VTX admin didn't work. So i deleted and rediscovered the sensors and VTX Admin works now with the ES900TX! I managed to reflash VRX and bind it with phrase and it works too.

#

For ES24TX - I did pick one drone that has 18 sensors and did the rediscovery but this didn't help on ES24TX 😦 And it didn't control VRX either. ES900TX can control VRX ant VTX no problem now, flashed with the same backpack firmware.
