F4 FLAME
#1
Hello I recently got new FC for my mian quad, because my omnibus corner have problem with gyro connection. 
I solder everything and I looks good, but I can get TX works. I Have TX1/3/6 but cant get TX signal from any of them. 

Any tips how to get where the TX is connected? Im running SBUS..

Here is the link for FC

You're saying TX, but are you really asking how your receiver is connected to the flight controller?

Hi,

What kind of RX do you have? Some screen shot from your betaflight settings would be also helpful.

If you would like to use FrSky SBUS receiver connect the reciver to UART1 (only UART1 has built in inverter for FrSky SBUS) and the following settings are needed in betaflight configurator. On Ports tab you have to select UART1 and enable the Serial RX. The next step is in Configuration tab select Serial Based Receiver for Receiver mode and SBUS for Serial Receiver Provider.

In betaflight COnfiguration I have selected
Serial based receiver
And 
SBUS

I tried  set RX on every UART 
In fact I have 1/3/6 nothing works


Here is screen of ports.

Hope I cover all needed info Smile

I can't see the screenshot of your ports tab, maybe it's just me?

Sounds and looks set up properly to me, can you upload a photo of the wiring?

Its the same as picture from the manual

Receiver is connected to 5v GND Sbus.
Receiver is normally turn on after power up the quad.

How I can test if the signal comes out from receiver with multimetter?

The TXRX 1/3/6 is somwhere else..

look on this pic.. 

uart 1 is left down
uart3 and 6 is top

So what I should configure to BF

After some reading, i think UART1 is the port for your RX.
You must not use RX1 pin on the board as it doesn't have an inverter... you have to use the dedicated SBUS pin.
Make sure you connected the right pin on the RX? I think Tom is right, it's best to post a picture of your RX and FC to confirm your connection is correct... just to be safe.
Last thing to check i can think of is SBUS_INVERSION in CLI... it's should be on?

Yup using sbus port fc

Not the best soldering, but will be cleaned after everything is set. 
Here is photo, for hires picture just link

Sbus_inversion had nothing to do with F4. It only works for F3.

About halfway down
