Hey guys, I'm having trouble getting ELRS to work. I have a HappyModel ES24TX and a HappyModel EP1, my FC is a SpeedyBee F405V3. I've succesfully flashed the latest FW on both the Tx and Rx. They are paired.

I've made sure the Rx isn't in bootloader mode, when I power off the radio, it starts blinking as expected. The Rx is soldered to UART2, I've triple checked the Tx>Rx and vice versa. I've tried both on USB connection and on battery. In BF, I've turned on serial on UART 2 and set CSRF in receiver tab. What could be the problem? Thanks in advance 🙂

#

apart from the extremely cursed wire colours your wiring does seem correct

#

could you show your betaflight ports tab and receiver tab?

pale geyser Nov 23, 2022, 12:14 AM

#

Oh yeah, I hate it too

#

next time make 5v red and gnd black, won't fix your issue but at least it makes sense

#

ok, connect to the rx wifi and take a screenshot of the webui

#

!webui

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

#

ok that's a weird one, nothing comes to mind rn

#

what does the led on the receiver do ?

pale geyser Nov 23, 2022, 12:19 AM

#

Oh and on the first bind, the lua script told me about a model mismatch, so they do be talking (fixed that ofc)

ebon crag Nov 23, 2022, 12:20 AM

#

so you fixed the model mismatch ?

#

was really hoping that was your issue aaaa

pale geyser Nov 23, 2022, 12:20 AM

#

When my Tx is on, solid. When I just turn on the quad, goes into wifi after 30 secs. expected behaviour

#

I mean I turned that off... thats okay right? 😄

ebon crag Nov 23, 2022, 12:21 AM

#

yes

pale geyser Nov 23, 2022, 12:21 AM

#

yeah, no more errors coming up in lua

#

my mixers should be okay, cause this is a copy of a quad I lost a year ago with the same Rx

ebon crag Nov 23, 2022, 12:22 AM

#

pale geyser

could you show the whole page with version and firmware target ?

pale geyser Nov 23, 2022, 12:22 AM

#

sure

#

RX

#

#

TX

#

#

oh version right

ebon crag Nov 23, 2022, 12:24 AM

#

was talking about the webui

ebon crag Nov 23, 2022, 12:24 AM

#

pale geyser

that same page but fullscreen

pale geyser Nov 23, 2022, 12:24 AM

#

#

this ok?

ebon crag Nov 23, 2022, 12:24 AM

#

yes :/

#

I'm really running out of things I can think of

pale geyser Nov 23, 2022, 12:25 AM

#

ebon crag Nov 23, 2022, 12:26 AM

#

you sure your mixes are right ?

pale geyser Nov 23, 2022, 12:27 AM

#

#

pretty sure, yeah

ebon crag Nov 23, 2022, 12:28 AM

#

internal rf is turned off right ?

pale geyser Nov 23, 2022, 12:28 AM

#

Well, I could try a different UART....

#

yup

ebon crag Nov 23, 2022, 12:28 AM

#

yeah at this point, might be worth a try

pale geyser Nov 23, 2022, 12:29 AM

#

ugh. I hate soldering these small pads

ebon crag Nov 23, 2022, 12:29 AM

#

takes practice

pale geyser Nov 23, 2022, 12:29 AM

#

takes patience 😁

#

welp, if you or anyone else has another suggestion, I'm all ears

#

but going to bed rn

#

thanks for your help!

ebon crag Nov 23, 2022, 12:30 AM

#

yeah I should to, sorry I couldn't be of help

pale geyser Nov 23, 2022, 12:31 AM

#

I'm glad you took the time to try

ebon crag Nov 23, 2022, 12:31 AM

#

you'll have to wait for more competent people to chime in

pale geyser Nov 23, 2022, 12:31 AM

#

when are those active? 😄

ebon crag Nov 23, 2022, 12:31 AM

#

and by people I mainly mean deadbyte haha

#

he should be on when you wake up

faint stone Nov 23, 2022, 1:32 AM

#

@pale geyser is that your actual bind phrase?
can you show us a screenshot of the Model Tab from the receiver's Web UI please

pale geyser Nov 23, 2022, 1:55 AM

faint stone Nov 23, 2022, 1:56 AM

#

on the radio, Model Menu -> Telemetry page, how many sensors are you getting?

pale geyser Nov 23, 2022, 1:57 AM

#

#

Are they supposed to be here?

faint stone Nov 23, 2022, 1:58 AM

#

pale geyser Are they supposed to be here?

yes.. discover new

#

there should be at least 9, more than that is good..

pale geyser Nov 23, 2022, 1:59 AM

#

got 18 new

faint stone Nov 23, 2022, 2:00 AM

#

pale geyser got 18 new

can you post a photo of the ExpressLRS Lua Script please

pale geyser Nov 23, 2022, 2:01 AM

#

#

quick question, will I see stick movement when the battery is not connected? I ofc tried with battery too, just curious

faint stone Nov 23, 2022, 2:03 AM

#

pale geyser quick question, will I see stick movement when the battery is not connected? I o...

if receiver gets powered up, either via usb or via Lipo only, then you'll get stick movements

#

can you show the Other Devices, select the receiver..

pale geyser Nov 23, 2022, 2:04 AM

#

faint stone Nov 23, 2022, 2:05 AM

#

hmm.. RCVR_INVERT_TX is NOT enabled?

pale geyser Nov 23, 2022, 2:06 AM

#

pale geyser

I can flash it again for peace of mind, but I'm 99% sure it's not

faint stone Nov 23, 2022, 2:06 AM

#

in the CLI, can you execute get serialrx and see whether serialrx_inverted=on

pale geyser Nov 23, 2022, 2:07 AM

#

faint stone Nov 23, 2022, 2:09 AM

#

clean up the soldering on R2.. might be shorting with the 4v5 pad

#

might also be ideal to resolder the green wire altogether..

pale geyser Nov 23, 2022, 2:12 AM

#

oh god, you're right

#

it seems to be shorted, according to my multimeter

#

wow, you really have a great eye, I never would have noticed

#

everything works!

#

thank you so much

faint stone Nov 23, 2022, 2:16 AM

#

pale geyser wow, you really have a great eye, I never would have noticed

my optician would disagree on that.. 😄

pale geyser Nov 23, 2022, 2:17 AM

#

I'll send a beer your way 😏 thanks for the support
