Hello, I need help.

With passphrase or no phrase, it connected as the binding light is solid green ( from flashsing green). If trying to turn off the TX, it said receiver still connected. If turn off the Crux35, it said telemetry lost. So I presume it's connected.
But when I go to Receiver and Modes tab on Betaflight 10.9.0, i don't see movements in Receiver tab. When changing Modes, no mode changes.
I have tried different BF firmware to latest. I downgrade ELRS to 2.5.1 on both TX and RX. Still no movements on Receiver and Modes tab.
I got stucked as no other scenarios to try.
This Jumper TX is working with all 3 quads using 2.5.1. This is first attempt to use 3.x elrs.
Thanks.

Happymodel CrazyF411 ELRS AIO 4in1 Flight controller built-in UART ...

The CrazyF411 ELRS flight controller comes with integrated UART 2.4GHz ExpressLRS receiver and 20A Blheli_s ESC(Bluejay firmware pre-installed) which could support 2-4s. Bigger Mosfet could support high to 20A currents would be better for 2-4S toothpick drone or long range FPV drone. And because the 2.4GHz ExpressLRS receiver is equipped with th...

Can you post a CLI dump?

#

Can you put TX and RX into WiFi mode and show screenshots of the webui?

#

!webui

Connect to your transmitter's or receiver's WiFi network to access the web UI:

#

What does the ELRS lua show on the Jumper?

forest pasture
reef grove
#

That should be set to 420000

forest pasture
#

yes, i did default 420000 not working, so i did 400000

reef grove
#

Leave it at the default

forest pasture
#

TX elrs version on Jumper: 3.20.0 ISM2G4 8d3388

reef grove
#

It definitely won't work at 400000

#

Can you show the model tab on the RX as well?

forest pasture
#

model tab ?

reef grove
forest pasture
#

ok, i will shortly. This new Crux35, they cramped the board, no wifi antenna, very weak

#

but i remember there is nothing on model tab page

#

i will reflash back to 420000 after it is on

#

but when it was on 420000 default, same issue, i tried many times on different version of elrs, even bring it down to 2.5.1 or 3.0.1 3.1.2

reef grove
#

What does the ELRS lua on the radio show?

#

You might as well flash everything to ELRS 3.2.0, making sure baud rate is left at the 420000 default

#

Then show a screenshot of the ELRS lua on the radio and screenshots of the webui on the TX and RX

forest pasture
#

ti did that earlier

reef grove
#

All you've shown so far is one screenshot that guaranteed the RX would not work. I'm asking you to fix those issues and show screenshots so we can troubleshoot further.

forest pasture
#

yes, i will. thanks. I will be offline to 10.0.0.1

forest pasture
#

hi, on the Jumper TPro , when flashing elrs 3.2.0, is UART Inverted enable or disable ? thanks

#

i looked now, it was Inverted Checked, so I like to double check to make sure

reef grove
forest pasture
#

yes, i read a thread, some guy has to uncheck

reef grove
#

Can you show the ELRS lua on the radio with the RX powered up?

#

Do you have an external module for the T-Pro, or do you have the Internal ELRS version?

#

If Internal ELRS, you have the wrong target flashed

#

It should be the T-Pro target

image.png
#

That would certainly explain your issue

forest pasture
#

i had internal runningmy 2.5.1, i added an external module, running my one new purchase quad pre-built 3.0.1

#

let me upload my lua

reef grove
#

Flash the correct target to your TX

forest pasture
#

btw, thank you for helping to diagnose

reef grove
#

Reflash your radio with the T-Pro target

forest pasture
#

my internal module is running 2.5.1, i don't want to give up 3 old quads

#

why ?

reef grove
#

Why not update them to BF 4.4?

forest pasture
#

this one is not working, why breaks my 3 working one

reef grove
#

Oh, so you have your T-Pro internal module flashed to ELRSv2 and an external Aino Nano flashed to 3.2.0?

forest pasture
#

btw, i did that, but it still gave same problem

#

yes,right now,

reef grove
#

I was confused, because you started with this:

image.png
forest pasture
#

but i did flash 3.2.0 onto internal, still same problem

#

sorry

reef grove
#

Can you show the model setup tab on your radio?

#

!externalrf

crimson valeBOT
#

The following image shows ideal settings for external RF

forest pasture
#

i tried all scenarios

#

yes, i have that

reef grove
#

Can you show a screenshot please?

forest pasture
#

let me up load

reef grove
#

Everything looks good as far as ELRS then

forest pasture
#

hmm, please look at the EP2400, screen above , it has Init Rate F1000

reef grove
#

Can you show a picture of the FC and a screenshot of the receiver tab in Betaflight?

forest pasture
#

the FC is UART built in , so only wires they did for camera

#

but i will upload the BF screens

reef grove
#

There is a way to disable the onboard receiver though

forest pasture
#

yea, short something they said

#

but like you said, it may not be elrs issue

#

brand new quad, i have not even mount the props

reef grove
forest pasture
#

in BF, it shows CRSG, Uart Serial based

reef grove
#

The BF CLI dump you posted looked correct, but you had the receiver baud rate set improperly

forest pasture
#

you meant 420000 ? now 400000 still no stick input

#

solid green right away when power both

reef grove
#

Again, it should be 420000

forest pasture
#

yea, i meant that

#

if it is not elrs, and when power up it does all the ESC sounds,then what else you think could be?

#

what causing no stick inputs?

reef grove
#

It seems like a communication problem between the on-board receiver and FC

#

So either a misconfiguration or connection issue

forest pasture
#

but it has only 1 board

reef grove
#

Have you flashed via the web flasher?

forest pasture
#

flash the firmware using betaflight ? yes I did

#

it has only 1 board and vtx, camera is ok, no other wirings except camera

reef grove
forest pasture
#

sorry I am off line for a bit

forest pasture
#

hi, what will ExpressLRS flasher do? I will do some reading. That is something new to me. Thanks.

reef grove
forest pasture
#

ah, it flashes the ELRS firmware to the board. Invert TX pin should be default to "No"
