FETtec G4 Kiss Issue - Bound, but nothing in GUI | ExpressLRS Community | Page 1

Afternoon all, I'm trying to put in a new FC (Fettec G4) but it doesnt seem to want to play nice with my Radiomaster RP3 and Zorro.
Both the Zorro and RP3 are showing as bound to eachother (Solid red light on RP3, Little C top right of ELRS LUA script) but I'm not getting any response within the Kiss GUI.

I've checked; Receiver set to UART 2 and TBS CRSF in Kiss GUI and wiring correct as per docs.

I've tried swapping RX and TX and also tried other free UART'S (1 + 4) and still unable to get Kiss to notice it...
(Also tried reflashing the RP3 with no change).

what RCVR_UART_BAUD do you have set?
is this a KISS v1 FC (pardon me, I'm not familiar with the hardware)

#

could you post a screenshot of the Receiver WebUI options and Model Tab please

#

are you getting Telemetry sensors on the radio? Model Menu -> Telemetry page, discover sensors..
with a LiPo connected to the kwad

Im not sure either. Assumed it was v2 but i'll give that a go now.

Yes, but only 10 (saw in a post somewhere thats relevant)

fallen leaf Yes, but only 10 (saw in a post somewhere thats relevant)

only 10 with LiPo (not sure if kiss requires separate setting for Telemetry) could mean that the wiring is incorrect.. like rx and tx swapped

#

or that the uart set for the RC link is incorrect

#

i.e. receiver wired into uart1, but rc is set to uart2

#

the baud rate of the receiver output also plays a factor..

#

try 400k baud rate for the receiver

No luck with 400k baud

#

recheck the wiring and/or config.. I don't see any reason you're not getting stick movements other than that, based off these screenshots.. aside maybe that updated receiver baud rate

#

there are boards that seem to call for TX to TX and RX to RX wiring..

#

or boards marking "Tele" as the TX pin, etc

I'll check over again. Im following the docs for the wiring and set to UART2. Also moved TX and RX to UART 1 and then 4 both ways around and no luck...
Im missing something... lol
