Setting up Ports

[quick sun]

You'll want to activate 'serial RX' under UART2 in the Ports tab and save

Did you flash BF with CRSF protocol?

[night garden]

I did not

[quick sun]

Is CRSF selected in the Receiver tab

[night garden]

Yes

[quick sun]

Do you get the light from the RX

I'm not getting it from FC
What do you mean

[night garden]

I am not getting the two beeps from FC for a total of 5. I only get 3

[quick sun]

You mean you have a beeper in ?

[night garden]

No the motor startup beep

[quick sun]

Oh the issue is the ESC config

[night garden]

yeah i need to enable my ESC in ports

just dont know which one

[quick sun]

No that's unnecessary

Unless you really want telemetry

[night garden]

all i have right now

[quick sun]

... I mean that's enough for a drone

But you should head over to the motors tab

[night garden]

and do what there?

[rocky dune]

What ESC is this?

blheli_32?

[quick sun]

^ ask the pros

[night garden]

SPAN G50A BLHeli_32 4IN1 50A 4-6S ESC

SpeedyBee F405 V4 Flight Controller: 30x30 Drone FC Wireless Betaflight Configuration

[rocky dune]

not a great combo lol

How've you wired them together?

[night garden]

Plugged in the 8 pin and made sure it was pinned correctly, plugged in the 6 pin same way. Wired my ELRS recivver to R2 and T2. USed a smoke stopper and everythihg boots up great with all lights functioning

[rocky dune]

elrs receiver you did rx to tx and tx to rx right

does that blheli_32 esc even have a separate telemetry wire?

[night garden]

On the 8 pin yes

[rocky dune]

I mean if that's true you just have to set the peripherals to ESC on the UART the telemetry wire connects to

but what's the problem?

[night garden]

WHen i set my serial RX to UART 2 and nothing else, I only get 3 beeps from the motors not the extra 2 from the FC. My 2 other drones have 5 total

[rocky dune]

Are you sure it's wired correctly?

[night garden]

The ELRS reciver?

[rocky dune]

The ESC and FC

[rocky dune]

and the ELRS receiver

[night garden]

I didnt change the pins, I looked up the wiring diagrams and ground matched groud and bat matched red. The motors are in correct order so im assuming TX and Cur are

[native hedge]

The last two beeps is the ESC saying it’s communicating with the FC. Something is wrong between the FC and ESC. Most likely the wiring

[night garden]

So I should look at the 8 PIN ESC to FC connector?

[native hedge]

Check both sides
Never hurts to double check

[night garden]

even when i try to move my motors within BF they dont turn on

[stone tendon]

You wired TX to RX and RX to TX, right? Not TX to TX and RX to RX?

What ESC and FC do you have?

[night garden]

SpeedyBee F405 V4 Flight Controller: 30x30 Drone FC Wireless Betaflight Configuration

SPAN G50A BLHeli_32 4IN1 50A 4-6S ESC

[night garden]

I just switched them to double check and nothing

[stone tendon]

Don't switch them, just make sure they're correct in the first place. It might not work if you don't have Betaflight set up properly

[stone tendon]

Great can you send a photo showing how they're wired together? Like disassemble the stack and show the FC and ESC side-by-side so we can see how it's wired

[night garden]

I had to go across bc they don’t fit going under

[stone tendon]

Wait where does this go?

[night garden]

The FC 8 pin I just unplugged it so you can get a picture

[stone tendon]

Do you have a link? I'm not finding one that looks like your ESC. There's a GEPRC G50A ESC, but it looks different than what you've got

[night garden]

Yeah I was just using that one

[stone tendon]

?
https://geprc.com/product/gep-blheli-32-g50a-4in1-esc/

[night garden]

Yes that’s the diagram I used. My FC lined up with the 8 pin so I didn’t repin anything. Plug in battery and FC fully lights up just missing the 2 beeps

[stone tendon]

Can you send a screenshot of your Motors tab in Betaflight?

[night garden]

Sure

[rocky dune]

carbon is conductive by the way...

[night garden]

What lead you to say this? What did I do wrong 😂

[stone tendon]

Are you sure the plug is correct? You might have to reverse the order of the FC wires from the ESC

It looks to me like ground should be closest to the camera

[night garden]

Yes im sure bc if the ground and bat went into Tel and Cur in wouldve short circuted

[night garden]

if you were to flip the diagram over like facedown the ground would be at the top and my ESC ground is at the top

[stone tendon]

Oh yeah I had the orientation wrong

[night garden]

Just weird im missing the two beeps and even within BF my motors dont spin at all

so I think my ports are messed up but DOge lord said they are fine

[stone tendon]

When you try to spin in BF, you have a batter plugged in too, right?

[night garden]

Yes straight into Xt60, no smoke stopper

[stone tendon]

Betaflight settings look right to me, as does the wiring 🤔

Have you tried it with everything off of the frame?

[night garden]

Yes

[stone tendon]

Do you get a voltage value from the ESC in Betaflight with the battery plugged in?

I think you can set Betaflight to use the ESC current measurement instead of the onboard measurement

In like the Power tab or something like that

Here we go https://betaflight.com/docs/wiki/configurator/power-tab

[night garden]

Full balanced 6s battrey says 4.31 V for me

[stone tendon]

That's using the FC sensor, not the ESC sensor

You should be able to pick the ESC I'm pretty sure

[stone tendon]

Yeah there you go. Might need to save and restart

[night garden]

I did still no luck

[stone tendon]

What do you mean no luck? Like it displays like normal?

[night garden]

I mean moving the motors

[stone tendon]

If so, that's fine, it just means the current sensor wire on the ESC works

[night garden]

oh awesome

[stone tendon]

Your Betaflight configuration is mostly stock, right?

Might be worth trying to apply the factory CLI dump again and see if that helps. Might be a resource mapping issue or something like that 🤷

[night garden]

how and hwere do I find the Dump?

[stone tendon]

I'll try to find it. Usually it's on the Downloads page of the manufacturer

Hmm... it looks like they don't actually provide one 😢 Can you go to the CLI tab, type in diff all and copy/paste that into a text file and upload that here?

[stone tendon]

Huh. It's odd that it's using a generic firmware target 🤔

You could try updating the FC firmware and and using the SPEEDYBEEF405V4 target

[night garden]

you know whats super weird

[stone tendon]

Get rid of all the circled ones

You're using a digital video system, right?
Also change the motor protocol to DSHOT600

[night garden]

i plugged in the battrey without BF connected and I have ) lights on my FC

[stone tendon]

Huh so that means the ESC isn't powering the FC

If you've got a multimeter you can measure the voltage on the ESC plug

You might not need to re-flash if it's a hardware issue

[night garden]

when i intitally plug in battrey it real quick shows red and white but no blinking blue and they dont stay solid

[stone tendon]

Yeah so check with a multimeter

[night garden]

my ground and 5V is showing 2.065V not a full 5V

on my FC

]=[

[stone tendon]

What's the ESC power output though

[night garden]

how do i measure that? the multimeter doesnt fit on the 8 pin connector

[stone tendon]

The pads on the ESC are connected to the pins

[night garden]

its showing 22.52 V on the 8 pin connector

on Ground and Bat

[stone tendon]

Okay that's expected

Might be that you've got a dead FC then. Do you have a different one you can test with?

[night garden]

it literally came in today

I had a dead FC bc i blew the 5V regulato so i just got this one today, no short circuts

[stone tendon]

Is it just the 5v regulator that broke? Like it was working with your ESC still?

[night garden]

well it was woeking fine then it shortr circuted so the whole FC was getting no power. even when i measured a ground and 5v pad it showed 0 but now my ground and 5v on new FC show 2.065

but its not showing a whole 5V

[stone tendon]

Yeah. It's also weird that it's not being powered by the ESC

Is this the same model of FC as the old one?

If it's a different model, can you fully disassemble the stack, and take a photo of the ESC and FC laid next to each other and plugged into each other? I know it's kind of a pain to disassemble but I just want to make sure

[night garden]

it works now, I pushed the pin further in even though I didnt repin

motors fully work now through BF

[stone tendon]

lol cool

Glad you got it working 😅

Your receiver's working too?

[night garden]

nope now i gotta rebind it

[night garden]

Any hints on getting RX into wifi mode, continually just blinks blue

[quick sun]

Normally it should start after 60sec

But BF passthrough is easier

(you get to avoid overheating due to the VTX being on for a while minute)

[night garden]

never had any luck

[quick sun]

Ah

Use the executable tho

[night garden]

plug into theback of my USB port of mac but the drone doent pop up

[quick sun]

You should use the Expresslrs configurator software

Oh wait

Mac you say

[night garden]

yes

[quick sun]

Is there a configurator for Mac

[night garden]

yes

[quick sun]

You should get it

In my experience anything web based sucks

[night garden]

but oin my other drone it was not working and the express lrs group said to use web flasher bc its jank on mac

[quick sun]

Oh maybe it's true then

[night garden]

but even if i do BF pass through or wifi i cant get it to my drone

[quick sun]

Wait

Here

[night garden]

My RX is having the issue

[edgy bobcat]

What issue are you having?

[night garden]

My RX will not go into WiFi mode. Just continually blinks blue

[edgy bobcat]

Have you reflashed it?

@night garden Which receiver are you using?

[night garden]

ELRS 900. It was connecting to WiFi then I reflashed it and it quit mid update and now WiFi will not go to the quick blue light flashing

[edgy bobcat]

Reflash it now

And let it finish updating

[night garden]

It won’t connect to the WiFi anymore I can’t flash it. Betaflight configuration won’t work just error and the expresslrs told me to use web flasher but betaflight pass through gets an error

[edgy bobcat]

Make sure that telemetry is off in betaflight receiver tab

Betaflight passthrough should work then

Assuming Serial RX is on in the ports tab for the correct UART

[night garden]

yeah its off still no luck

[edgy bobcat]

the widi does do a wifi quick flahsbut then doesnt stay
