binding elrs to controller

[rough robin]

Hello good morning

Hello i seem to be stuck i updated the fc to the latest betaflight and i cant get elrs to work on the fc

[late void]

can you please give some particulars?

[rough robin]

Idk what u mean by that but its a f411 flight controller my radio is a jumper t pro running elrs 3.0.01

[late void]

which exact drone/fc and what receiver does it have?

[rough robin]

I got a skystar double brass antenna

And the drone is a home build geprc f411 stable. Aio

[late void]

then you need the receiver to be updated to the same firmware major version (3.x) as the tx

[rough robin]

Ok and how would i do that i thought it was a simple solder

I mean as long as the radio was up todate

[late void]

you can use this as a general guideline to get your receiver updated:

[rough robin]

Ok

[rough robin]

@late void sorry to bug but i seem to have ran in to a problem i cant get the wifi on the receiver to active i also tryed looking for it mainly but the http elrs rx wouldnt pop up on my browsers

This is were im stuck at

[late void]

what does the LED on the receiver do?

[rough robin]

Its solid

[late void]

is it blinking rapidly indicating wifi mode?

[late void]

has it ever blinked before when you powered it up?

[rough robin]

Tbh idk

[late void]

you did soldered this receiver yourself to the FC, correct?

[rough robin]

Yes

I followed the diagram

[late void]

is that LED just dim?

[rough robin]

Yea

is it broke

Did i kill the poor thing

[late void]

can you verify the wiring please.. make sure none of the pads are shorting..
also, is it insulated from the conductive carbon frame?

[rough robin]

It is not its zipp tyed right to it

Keep in mind this is my first build

And there no short i tested each borad separately and to gether with a multi meter

After soldering the test were conducted

[late void]

can you verify the receiver is wired correctly then?
GND
5V
RX pin to a TX pad
TX pin to an RX pad

[rough robin]

Now ill send u the diagram i followed

Yea i second

1*

i was told this was the same as elrs

[late void]

disconnect the RX and TX wires of the receiver from the Fc and see whether the receiver LED will blink..
if that's the case, find a different uart to wire up the receiver to

[rough robin]

Ok

@late void

It still doesn’t

Blink

[late void]

you are plugging in LiPo or it powers up with just USB?

[rough robin]

Usb

[late void]

what about you plug in LiPo to see whether receiver would power up normally

[rough robin]

Yea it blinked once the got realy bright

Then*

Its solid bright know

Is he dead

[late void]

is the button on the receiver being pressed?

[rough robin]

No

I got it separate when u asked to disconnect the tx and rx

[late void]

by any chance, do you have an ftdi/uart adapter?

[rough robin]

No sorry

If hes dead its ok i can just order a new 1

I dont wanna waste ur time

[late void]

it's not yet dead..
but recovery for you right now might be tedious..
I would suggest getting a new receiver
and perhaps a UART/FTDI adapter

you will need to wire the new receiver into a different UART

insulate/isolate it from the conductive carbon frame when you mount it

[rough robin]

ok

Any brand of receiver u recommend

Price dont matter just a good one with least problems

[late void]

they all should work okay..
avoid JHEMCU and Flywoo and other off brands.. (non-verified hardware)

[rough robin]

Ok
