Hello, how can I know if a uart is bidirectional? I got a geprc f4 stable flight controller in a very small quad copter and it doesn't have a telemetry pad just the sbus pin and TX 1 pad, I can't make it works with the r-xsr, did you use the normal smartport wire or from the "p" pad on the receiver?
So F4 boards are the most complicated when trying to get telemetry you're gonna have to use the uninverted signal from the r-xsr to get telemetry to work
The SBUS pin on an Omnibus F3 FC, is it RX or TX? I was putting the S.PORT wire there, trying to get FPORT to work, but can't seem to get it working. I needed TX1 & Tx2 for GPS & S.Audio. Thanks
I have searched everywhere and cannot find any information on my question. I’m using a Lumenier F4 AIO and not sure if the users are inverted or uninverted. It has a dedicated sbus pad but no dedicated telemetry pad. I already ordered the r-xsr and already I’m afraid I’m gonna ruin it just trying to get it to work lol
No need to be afraid the new r-xsr has the uninverted pads on it and I've used them for smart port but not f.port but I have gotten f.port to work on a f4 omnibus without a telemetry pad so what I would do is when you get the receiver try regular sbus with the sbus pad make sure that works then you can try to flash the r-car with f.port and connect it to the TX pass and see if it works if not you will have to use the uninverted pad on the r-xsr
I have a omnibus f4 pro with frsky R9mini flashed with Fport have it hooked to uart TX1 and no luck try duplex on invert on can't get it to work also I'm running 2.0 Inav but should be the same
ridesoftail you just have to make sure you are hooking up to a bidirectional TX pad and also you need to put in the special commands in the CLI tab I've only gotten Fport to work once on an f4 board but on f3 and f4 boards with a Telemetry pad it's No problem
If the CL racing f4 fc has a dedicated telemetry pad you won't need to use the uninverted pad from the R-XSR you can just wire up the S.Port Wire to the telemetry pad and you'll have F.Port
@@paulopc77 I don't see an option to lower that, maybe set your low alarm higher? I used to hate the sound of it saying it over and over so I ended up setting my low alarm so low at 45 and it never said anything until I got super far out
Yes you can but you gotta make sure the UART your'e putting the smartport wire on is bidirectional, on F3 boards its not an issue but if you have like an omnibus f4 which doesn't have a dedicated telemetry pad then you'll need to either figure out which 1 UART is bidirectional or just use the uninverted signal from the smartport pad on the R-XSR
Need help! NWhich telemetry output? In ports tab Smart Port? Frsky? Eh I've tried both... I have no idea why this isn't working I've done everything step by step. I've got the flex firmware, on everything, but either way the uart is the ports just won't stay in what i set it to, so something's screwing up. I'm using the slim+so i used the uninverted s. Port wire to go to tx3 on lumenier micro lux v3 so i wouldn't have to use soft serial inversion, and i used the cli set of commands for f4 with receiver uninverted.. I've got it set to fport, serial based. What am i missing? It's uart3 so i copied cli as was, used for 2(uart3) in0=uart/tx1 1=2 2=3.
What ranges are you getting of your r-xsr? I have mine setup via fport, with telemetry, and my x-lite tx shows 80% rssi when tx is next to the quad. When flying 100-200m away, i get low rssi warnings. Anyone else had the same issue, or does someone know how to fix it?
That's really weird, i have about 3 r-xsr's and they all give me great range i even go crazy far sometimes at LOS but maybe its the firmware, did you update to the latest version of fport?
@@migfpv1790 it very well could be that, I did have a problem where my r-xsr only worked with ppm not sbus and kept failsafing, maybe try regular sbus and see how the range is
I have the same issue. I’m using mine on normal sbus and it failsafe about 200ish meters I almost lost the quad. I tried replacing aerials and it’s the same. I am here to change to fport thinking it might help but now I see there’s probably no point. I’ve seen other with similar issues while searching for an answer I’m really fed up with it now
@@JohnDoe-or3hc I would give PPM a shot and see if it still failsafes, if it does then it could just be a faulty receiver, normally as soon as I get a receiver I range check it but the r-car has has ton of problems i actually switched over to the r9 mini and it's really good so far
So my rssi in the same room is only 30, I know there's a setting or two you supposed to change for this, something from 200 to 100.. shit I can't remember what it was. Do you know what I'm talking about or how to fix the low rssi for fport
Oh there's a setting for that I'll post it for you when I get to my taranis but basically you have to search for sensors in the taranis then you'll see the rssi the on the channel page you'll have to assign it to a channel I'll post the link to the video I used
@@dwarfstarfpv2056 Yea it wasn't the channels I don't think..no not there, I'll take the link anyway but the xlite was showing full bars for connection, the xlite sensors has 100db rssi, the osd has 30.. I'm gonna try the scale 200 cli command, that seems like the one I couldn't remember, Bardwell mentioned it when I was like the xlite seems to be full rssi but the monitor says 30
Chi Sty I had the same problem and what solved it was soldering the signal wire to a TX pad instead of RX but fport has just given me problems non stop maybe the new update of the r-xsr fixes all the problems
@@bastier8984 sorry about the late reply UA-cam doesn't even let me know when someone comments back.....on that FC there isn't a dedicated s.port pad so you can do 2 things flash the latest version of f.port to your receiver and try hooking it up with the sbus pad because it has a built in inverter or just use regular s.port because you do have a lot of UARTs on that board and honestly man f.port has been horrible to me lately I swapped back to much bugs
Thanks! That set of CLI commands what just what I needed to get my FrSky R9 Slim + setup on my Matek F722 Flight Controller. Much appreciated!
Nice glad I could help !

Do you copy and paste all CLR commands at once or one at a time?
Love the hobby, the learning curve is so frustrating...thanks for your help
You can do them all at once

Chuck Horton The s.port wire has to be hooked up to a TX pad, maybe you can use smart audio on a soft serial and have f.port on a TX uart

ridesoftail Hey bud you gotta make sure that uart port is bidirectional, does your FC have a dedicated telemetry pad ?
No I guess if I use a R9slim + once they have Fport firmware I should be able to make it work.
ridesoftail you just have to make sure you are hooking up to a bidirectional TX pad and also you need to put in the special commands in the CLI tab I've only gotten Fport to work once on an f4 board but on f3 and f4 boards with a Telemetry pad it's No problem
would using f.port make it so that when using rxsr the wiring can connect without using the inversion hack on the newer cl facing f4S boards?
If the CL racing f4 fc has a dedicated telemetry pad you won't need to use the uninverted pad from the R-XSR you can just wire up the S.Port Wire to the telemetry pad and you'll have F.Port
Which wire on the R-XSR did you use? The S.Port or the SBus wire?
Ryan Cheesman The s.port wire
Hi how are you?
Please let me know if possible where I can decrease the "refresh" time of telemetry in frsky taranis x9 lite?
Hey, so you want it to read out telemetry faster ?
@@dwarfstarfpv2056 yes, mine takes 15 seconds to update!
@@paulopc77 I don't see an option to lower that, maybe set your low alarm higher? I used to hate the sound of it saying it over and over so I ended up setting my low alarm so low at 45 and it never said anything until I got super far out
@@dwarfstarfpv2056 thanks!
Couldn't you just solder from the wiring harness on the receiver instead of soldering wire and the smartport pad?

You don't have to set that in the ports tab just turn on telemetry in the configuration tab and set your serial rx to f.port and you're set

I got the channels moving but can't get the telemetry to work. Not sure what I'm doing wrong...
Chi Sty Make sure you turn on telemetry in the configuration tab, and make sure your signal wire is hooked up to a bidirectional TX pad
DwarfStarDrones I think I did all that....I gave up and went back to sbus.
Chi Sty I had the same problem and what solved it was soldering the signal wire to a TX pad instead of RX but fport has just given me problems non stop maybe the new update of the r-xsr fixes all the problems
Why does that always happen? Funny sometimes I wanna smash my laptop
I've used rx pads by mistake too dumb
Nice vid
lol yea it happens, what really sucks is when fport stops working and you gotta go back to ppm smh thanks man !
