Kopis 2 (Kakute F7 v1.5) PNP (R-XSR rx) Detected 0 radio

PX4 Autopilot
1

Continuing the discussion from Omnibus F4 SD:

I finally bought PNF version of Kopis 2 with Kakute f7 1.5 and as receiver frsky r-xsr.

I flash PX4 as there https://docs.px4.io/master/en/flight_controller/kakutef7.html
But “detected 0 radio channels to operate px4 you need at least 5 channels” issue is continuing.

On PNF version receiver connector cables are pre soldered.
when i connect r-xsr:

r-xsr connection- - - -kakute connection
----- gnd - - - - - - - - - - - -Gnd
------5v - - - - - - - - - - - - -5v
------s-port - - - - - - - - - - T6
------sbus-out - - - - - - - - R4
------sbus-in - - - - - - - - Not Soldered

Am i need make any corrections on Parameter list via QGround?
Or anything else?

Hi
SBUS out should go to R6.

Actually did you select the Kopis airframe? Then it should work as well.

Hi @bkueng,
Sorry for late response.

I change Sbus-out and S-port solders to
Sbus-out -> R6
S-port -> T4

And,

SYS_AUTOSTART = 4053

For now everything is fine.
Maybe some info about soldering can be added to https://docs.px4.io/master/en/flight_controller/kakutef7.html

Thanks for supports…

Now I’m working on corrections esc etc. parameters and will try to add PX4Flow sensor.
