FrSky FPort lets you run SBUS and SmartAudio over a single wire. This makes for a cleaner build. It also frees up one UART on your flight controller, so you can connect to some other kind of peripheral. If you're interested in checking out FPort, I'll take you through each step.
First you should watch my video on how to flash firmware to FrSky receivers: • FrSky Receiver Firmwar...

JB; as you probably have seen. I had struggled this entire weekend trying to get the receiver configured. UGH! Even went out and purchased another RX thinking mine was AFU! This video solved my issue. Thank you so much! Now, I can call PriroFlipRC and tell them to cancel my order. Nah! I'll have a receiver to give to someone when they need one. I was given a whole bunch of free GOOD advice when I started. It's the least I can do to help another individual just starting out.

@leznets91 6 лет назад

YES the intro is back, I'm so happy.

@eee.1013 6 лет назад

Bought some R-XSR last week, this "HOW TO" video is on point ! :D

@marinehm 6 лет назад

Hahaha. Subjected to watching videos while I'm saving for my new build. Yes, I lost my 1st one. I think someone snagged it faster than I could get over to where it went down. But in my setup, I was having trouble with the telemetry. It kinda worked. This explains what I did wrong and how to set it up correctly. Thanks JB! Hense "FPV knowitall". Title well earned.

@HDgodfrey 6 лет назад

So cool Josh! I need one extra uart and run an x4r. I Can't wait to get home and give this a try. I can't say thanks enough. Going to start using your links for all my shopping! Thanks so much!

Thanks for this video!! I feel like you made it just for me after our conversation about freeing UARTs for GPS. Regardless, thanks for the great info JB!!!

@petehelme7714 6 лет назад

Hmm, this is cool. Joshua, please keep these great videos coming! I just did added SmartPort capability on a Flycolor S-Tower (F3), using Pin 6 of the PWM (10-Pin) connector to a FrSky XSR. Supposedly on this FC, if you use the supplied SmartPort pad, it's shared with the USB bus and complications ensue using them simultaneously, so better to use a free TX pin and SoftSerial. I'll have to try this F.Port mod soon, but since everything is working now, I'll wait. ;)

@DopeJohnny 6 лет назад

I guess that's the price for a massive, powerful, feature loaded piece of software that can run on even very simple (and cheap) electronics and can be controlled by just 6 buttons. When I got my Taranis I tried to not change anything that I had no clue of... that worked well for me.

@hateeternalmaver 6 лет назад

When I got my X4RSB I was looking into using Fport because I have an F4 but I found the uninvert hack less of a hassle than flashing new firmware to the receiver.

@renedevries143 5 лет назад

Great info. I got my r xsr hooked up to my kakute F7 (f port) and it works awesome. I did remove the sbus from the r xsr, Problem is the barometer on the F7 is now not recognized in betaflight and not showing. Any thought how to recover the baro?

@Jord0699 6 лет назад

I used to use the same model for all until recently as mid and end points would always be exact. Do you play with this? I imagine you could adjust it from with FC instead of controller if you wanted?

Whats up bardwell? I need some help with getting my qx7 to work with my r-xsr. Im using the pyro f4 osd fc and flashed the firmware to the r-xsr for fport and lua scripts. Im bound to the rx and appear to get telemetry but dont get any stick movement in bf. I tried the tele pad and tx4 on the fc and neither worked. I've also tried the serialrx permutations in the cli. I'm new to taranis and not getting any help from my fb groups that I'm a member of. Please help me! Thanks bud

@shaiss1 6 лет назад

thx for the video. for anyone that this doesn't work. if you dont have a telem/sp labled pad and using a generic uart, make sure you're on the TX pad and not RX. If you are using an rxsr and a generic tx pad you will need to use the uninverted p pad on the rxsr to get telemetry to work

@nevinleiby 6 лет назад

It's still not working for me on HGLRC XJB F428. I've tried all 4 combinations for inverted/half duplex as well as inverted and un-inverted hacks...No change. Not receiving any stick input on BF 3.3.2

@Super73VW 6 лет назад

Hey Joshua, I am using your RDQ F4-AIO, and the FrSky R-XSR. I have quadruple check my wiring, and it seems correct for the setup. In Betaflight I have set UART3 with Serial RX on, and UART 1 serial RX disabled. Receiver configuration is set as serial based and FrSky FPort. My XD9+ and the receiver are bound as indicated by the solid green light. On my transmitter my channels are set as AETR, and in the outputs they all put out the correct uS range when going through the throws. My problem is on the Betaflight screen when on and connected, my channels do not move. All channels are at 1500uS except throttle, Aux 13, and Aux 14. I am just coming over to FrSky from Spektrum, so there are quite a few new features to me. I also went through the New Taranis+ setup video to see of I was missing something on my initial radio setup. Edit: Using Betaflight 3.3.2, and configurator 10.2.0

@gpletcher70 5 лет назад

So I’m wondering should I try to reflash the rxsr receivers or should I update the firmware on my x lite radio And see if that helps me connect and get good signal out of the receivers

On the New Mamba F411 AIO 25A ESC, they have both, RC tx pad and Inverted pad(s.port) on UART 1. Do I have to desolder the RC signal for f port to work?

hi. just brought a taranis x9d plus and when im trying to bind any receiver on the transmitter nothings happening. no chirping from the x9d plus when i click on bind. need help or is it broken firmware v2.2.2

@kosti116 10 месяцев назад

Hi Joshua. First of all, I am very grateful for all the work you put into your videos. I gained a lot of useful knowledge from them! I have a rather unusual problem. My fc is AIRB/OMNIBUSF4SD(STM32F405) BF version 4.3.2 (it doesn't work at all on other newer BF versions) Radio X9D+ se, soft RF module XJT_ACCST_2.1.0_FCC FrSky XSR ACCST receiver (X4RXSR_ACCST_2.1.0_Fport_FCC) s.port not modified, connected to FC on a dedicated s.Bus pad. The controls in the receiver tab work (sliders move) but telemetry does not work. As for CLI, I checked all configurations. The set serialrx_inverted option doesn't change anything in my case. The set serialrx_halfduplex option must be set to OFF for the control to work. I'm at a loss because before updating to the latest BF version, everything worked fine, I had all the telemetry (it worked normally on software 3.2.2). I will be grateful for any help :] Regards !

@oligarcia1 3 года назад

Hey Bud! Thank you for all the videos you are always such a great help. Unfortunately I have not been able to bind my RXSR to my QX7. I've updated the firmware on my transmitter and have tried flashing almost all of the firmware updates for RXSR. I've tried all the ACCESS updates because thats what my transmitter asks for. The closest Ive gotten to binding is up to the register point but then it won't bind. This is my second receiver because i busted the first one which was a diatone msr. PLEASE HELP. Thank you very much!

@morgattfpv5548 4 года назад

hey, i installed a r xsr with f-port on my hobbywing xrotor g2 stack and the reciveing works fine, but i dont find any sensor more than rssi and rxbt, but in my matek f722 with r xsr and f-port i found 14 sensors. do you have any thoughts what i could have doing wrong?

@countryboymotovlogs926 5 лет назад

Hello Josh, im new to open tx after yrs of spectrum im trying to get a 5 inch setup qx7 the receiver your using in this video. I have the lux V2 FC. I wired the rec as you described. My problem is i cant get the rec. tab in BF to work. On the lux v2 the serial rx is uart 4 the tx is uart 5 i have the serial turned on uart 4 and in config i have serial rx and sbus on, is that wrong?

@Ununpentius 5 лет назад

Joshua if I flash my X4R-SB for F.Port will I still be able to use the original SBUS connection on the end of the receiver for controlling a gimbal for example?

@mrjusten100 3 года назад

Can I connect the Fport from a R9mini to the SBUS pat on a f4? Both are inverted, so it should work? Okay maybe dumb question, but I'm very new... Inverted TX pat is not = RX pat? So there are 4 option Tx inverted/uninverted Rx inverted/uninverted I have an old DYS f4 AIO with just an SBUS pat... so it won't work with Fport?

@imothy 3 года назад

I have an x-lite running opentx 2.2.4 and a crazybee F4 board trying to add an R-XSR. I can bind and fly the quad using sbus with the rxsr firmware 191112, but when I flash the fport firmware 191128 I can bind but I can't get activity in the receivers tab. I'm using the "inverted" pad on the R-XSR and set serial inverted off as well as half duplex on. Telemetry is turned on in betaflight as well as fport is selected as the protocol. Not sure if i'm missing something...

@sparrow082 6 лет назад

So I just did the fport conversion on my Matek-f405 with my r-xsr on urat 2, the S Bus pad. I'm running inav and everything seems to be working except telemetry I'm only getting the r-xsr telemetry. My taranis is only running open TX 2.1.8 I'm guessing that this is the problem but I'm leery to upgrade to open TX 2.2 when previously updating my radio open TX prompted me to update my internal module and then bricked it and I had to replace it.

@philippeglur 4 года назад

I wonder if Joshua or anybody else can help. My new Archer GR8 receiver does not allow me to plug a sensor using the standard servo plug anymore. I had it working with the pre-ACCESS RX8R Pro as the Smart Port plug was for standard servo plugs. Do I have to use that new 4-pins F.Port connection now? If so, I guess I need to change the plug on the sensor side. Just a bit unsure, as it is, as usual, difficult to get clear info from FrSky. Any help is highly appreciated.

@shinuza 4 года назад

Also, be careful not to accidentally enable PPM when first binding your receiver. Otherwise, you gonna have a bad time. On the R-XSR if your inputs do nothing in the receiver tab, check that you a blue led and a green led, both solid.

Either way, I got it working on one quad, and killed an RX trying to be smart and hook up the uninverted s.port pad to the sbus-in pin (on the RX, not on my FC.) so I could just use the connector. I don’t know if it’s just bricked or totally fried.

@bewing77 5 лет назад

Hey Joshua, thanks for all great videos, they are really great when you are new to this hobby, even me as an embedded software engineer for two decades stumble on these things sometimes. I have a question about this, which may be to specific, IDK. I have a Diatone GT M530, which has their Mamba F405 FC. It's good, but it's woefully lacking in documentation. It has three UARTs, none of them specifically labeled for a specific use - I've been able to discern that UART1 seems to be able to handle inverted signals since I can hook S.Bus directly to it and it works: So currently I have S.Bus at UART1 and SmartAudio on UART3. For SmartPort I had to solder a wire to the non-inverted pad on my R-XSR receiver, It had me scratching my head for a while since it got delivered with a harness wired up seemingly to fit an R-XSR, but with SmartPort going to the normal, inverted SmartPort pin on the receiver. Anyways, given this FC, which has no Telemetry/SmartPort/Whatever name for an inverted UART, do you think F-Port would work if wired to UART1, which now is wired to S.Bus without any external inversion? Cheers

@JawaPaul 5 лет назад

This is a good question, and would answer my dilemma also with the DYS F4 Pro V2 ..... Should we just flash F.Port FW to R-XSR , then connect the S.Port wire from R-XSR to the same TX-1 pad that is working out of the box with Sbus ??? (And modify BetaFlight etc) But as it's an old video, I don't think Joshua Barwell will hear our cry's in the wilderness that is RU-vid. He must get literally thousands of notifications every day :) Joshuaaaaaa ;)

Hi joshua Jumper r1 f-port receiver fault as on most i have seen online when binding both lights light up but you have green led on outer edge of board and red on inner which flashes in bind mode and green goes solid after power cycle the receiver i have was got last week and when i put in bind mode red is on outer edge of board and green on inner when binding green light flashes and after power cycle red light goes solid it seems to be connected Another point was to get it to bind i had to change RF fine tune freq to -15 it will not bind at RF fine freq at 0 should i trust this receiver i have heard of other people having problems with bind procedures on this reciver

@JoshuaBardwell 4 года назад

Needing to frequency fine tune is normal for the multiprotocol module. You can find a tutorial on how to do it on Grayson Hobby youtube channel.

@-xk140-2 6 лет назад

Dear Joshua, thanks for all you do for us. I finally succeeded to wire the f.port. I still have a question. As I use the tele pad for fport, I wanted to use the the sbus pad to wire a gps beitian bn220. For doing this a need a free rx tx. I currently use tx4 for my tramp, rx6 for esc telemetry. Is there a solution to wire it on your fc. By the way the design of your board is awesome. So easy to wire.....thanks. Florent from France. Take care....

@JoshuaBardwell 6 лет назад

The SBUS pad on my FC has a switchable inverter so you can use it as a generic RX. But the corresponding TX is not broken out so it's not as useful as you might prefer.

@HausJan 3 года назад

Thanks for your great content. I have the problem, that even if set up correctly, at first both reciever values AND telemetry values work just fine. After some seconds, Reciever still reacts to stick inputs, but the telemetry (only the stock values RSSI etc. keep refreshing) loses connection. In Betaflight, however, RSSI is still picked up, telling me, taht at least the communication RSXR-->FC is still active. When i repower the FC, the same thing will happen over and over. Anyone else had this WEIRD behavior?

@saittafpv5846 3 года назад

my sbus stop working when i tryed it only will work on ppm i tryed to even use sbus wich diff reciver not even f port just at less work it was just fine be for this

@mark1944 4 года назад

right i have resolved the problem. sorry for the confusion but hopfully it might help somone. it looks like frsky had the latest firmware package as 191112 and had fport and sbus versions inside as usual but like i said the 191112 fport version would not work with fport in betaflight. as of today 29/11/19 the same 191112 package says (191128 Fport) in the description and contains 191112 for sbus and 191128 for Fport so it looks like some kind of screwup form frsky. 191128 is working fine following this video. many thanks

Have you ever seen where the Receiver tab isn't live but stutters? First time ever I have seen this.

Make sure you connected TX to RX and RX to TX between the Nano and the FC. A lot of people get the wires backwards. Enable Serial RX on UART 6 in the Ports tab In the Configuration tab set serial receiver protocol = CRSF

@JoshuaBardwell 4 года назад

You would need three UARTs for that. The Tramp Telemetry could be handled with softserial so only 2 hardware UARTs needed. The FPort requires a hardware inverter or you can use the RXSR P pad which outputs inverted smartport. I think probably it can be done.

Flashed my rxsr and my qx7s accst. Works for that particular drone, but now none of my other drones will bind to that transmitter. They are all xm+ and a Mobula 6. What do I do to get them to work again?

can you please review and setup the frsky R9 receiver with the R9M module and compare that system to the crossfire one? thanks!

@JoshuaBardwell 6 лет назад

Yeah I have it on order.

Does something need to change when you allready wired everything up for the old way? or can i just leave everything as is and flash the new firmware?

@JoshuaBardwell 6 лет назад

No wiring needs to change. The wiring is fine. But how will you flash the receiver?

Hi JB, Great video!! Wondering if Fport can be connected to SBUS pad of a F4 board?

@JoshuaBardwell 6 лет назад

No. TX pad only, with bidirectional inverter. SmartPort is the most likely choice to work.

@xuxusito 3 года назад

Is there any drawback for using this like increase of latency since now 2 types of signals are being communicated with the same wire? This seems just too good to be true?

@JoshuaBardwell 3 года назад

Actually, Fport has lower latency than SBUS.

Hi Josua ,great video :) question tho.. do you know if the speedybee f4 aio FC is able to use the FPORT setup? I am running speedybeef 3.5.7 on my speedybee, flashed fport firmware on my r-sxr reciever, connected the s.port wire of the reciever, set FBUS in settings tab, however: only on uart 2 (default reciever/sbus port) i get stick output on in the transmitter tab of betaflight but no telemetry on the radio. I know I shouldnt use the uart 2/sbus for flying but instead use a different uart. however i never get the stick output shown nor telemetry on my taranis q x7. tried uart 3 and 4 with half serialrx_duplex on/off, and serialrx_inverted on/off but no telemetry nor stick reaction on the transmitter tab.

@JoshuaBardwell 5 лет назад

For FPort, you must use a UART TX pad with bi-directional inverter. You say you are using UART 2 SBUS port, which is an RX pad. That would explain why telemetry is not working. SBUS has a one-direction (RX only) inverter. Use the SmartPort pad on your FC if you have one. Or use the P pad on the RXSR, which outputs un-inverted smartport (and Fport). Connect the P pad of the RXSR to any UART TX pad on the FC. Then in the CLI type "set serialrx_inverted=on" then "save". I don't know the correct value for halfduplex but try it either way to get it working.

@VilleF1N 6 лет назад

How are the stock antennas on R-XSR? Is it a good idea to straight up just strip them to 33mm instead of leaving them however short they come out of the box?

Hey Josh. I'll be building my first quad later this summer. I have a Frsky X-Lite and an R-XSR on order and I'll be using an HGLRC F4 Flight controller+ESC combo. If I use the F-Port method, does this mean I won't have to do the uninvert/invert solder hack on the R-XSR's tiny solder pads? I haven't touched anything RC since the mid 80's when I raced 1/10 scale on/off road cars(a carbon fiber Predator) and buggies(Tamiya Hornet)with crystal radios,pot style servo controlled speed controls, and brushed motors(who remembers "Reedy" in a can? Haha I'm trying to do tons of research way ahead of my build(getting my ducks in a row) I'm so thankful for RU-vid and all your videos! I can't wait to get on a sim and then fly FPV!!

@JoshuaBardwell 6 лет назад

If the HGLRC F4 has a smartport pad then you do not need to do the uninvert hack. From the question, I am guessing it does not have a smartport pad, and then you have to do the uninvert hack.

@MarcelloScardi 3 года назад

Great video as always!!! What if I use the uninverted SmartPort pad on the R-XSR and wire it to a TX pad of an F4 FC??

Hi, quick question if I understood correctly, on f4 like JB AIO, connect the smart port wire after flashing to fport to the T on the f4 board? Thanks !

@SomethiingClever 5 лет назад

I have f port working soldered on the pad on r-xsr and have serial rx UART 1 and connect that wire to sbus on mamba f405 mini. In your reciever tab you have telemetry set to aux 3. It's that because you're using uart3 or... What? I don't know what to set that aux to. I have an x-lite so I need to do something with that? I get rssi and vbat but don't know if I'm missing something out...? I also did nothing with inversion. I have no clue about that. It works and flies so it didn't fry anything...

@JoshuaBardwell 5 лет назад

If you are using FPort, don't wire to the SBUS pad on the FC. Wire to the SmartPort pad.

@SomethiingClever 5 лет назад

@@JoshuaBardwellThanks for the reply. On the mini mamba or any other f4 fc I've come across there's never been a pinout titled 'smartbus' so I guess I'm not understanding it. In the ports tab I need to select and solder to the corresponding UART port and just select serial rx. And not select smartport on that selected port. Currently it's working as far as I can tell going through sbus. It flies and I have telemetry. Is betaflight not telling the fc that the sbus port is being used as fport in the configuration tab? goo.gl/images/qbJqnP

@bobsterit 5 лет назад

Joshua, So if F-port will not work on softserial, does this mean I need to reflash my receiver back to a non-fport Fw to have s-port telemetry?

@JoshuaBardwell 5 лет назад

Smartport telemetry is included in fport. That's the whole advantage of fport. That it does telemetry and control in one wire.

@sunshynff 4 года назад

On your other F-port video you said you only need 3 wires from rxsr, how come here at 3:05 it shows you have 4 wires, the green still being connected to the sbus pad. I'm trying to connect an RSXR to a Talon F7, I can get my QX7 to bind to rx, but I can't get any stick inputs through betaflight and getting an RX_Failsafe error. Using Tx4 as my fport . Thanks for the video though it still helped answer a few other questions.

@JoshuaBardwell 4 года назад

I left it connected since there was not benefit to removing it. I was originally running SBUS and it was required.

@sunshynff 4 года назад

Joshua Bardwell, thank you sooo much for the quick response! i found my problem, must have read pinout wrong, but had signal wire connected to TX1 not TX4. Btw. since the quarantine, catching up on quad repairs, my newly made JB smoke stopper saved two different quads from magic smoke. Thanks again!!

@DominiqueRatte 6 лет назад

Hi J.B. is there a way to use the inverted sbus signal pad with inverted s port? I tried a few months back on a hglrc xjb f440 with the rxsr. there is a uninverted signal pad on the bottom near the plug but I don't have any other uart available. i depin the sbus wire and pinned it to the s port wire. via the plug which is inverted. thanks in advance I tried the both cli commands and and all 4 combinations to no avail. Maybe the sbus pad does not work as tx pad as far as software is concerned?

@JoshuaBardwell 6 лет назад

No, that's not going to work I don't think. If you do the uninvert hack, you must connect to an uninverted UART. If you connect to an inverted UART (like the smartport pad), you must send an inverted signal.

@DominiqueRatte 6 лет назад

Joshua Bardwell ok, thanks for your reply hopefully new fc boards gives us more than 3 uarts... To bad reciever UART isn't available for us users that use crfs. So theoretically I could use smart port tlm on that pad but wouldn't it need a Rx pad? Thanks for educational videos man keep it up 👍

Hi Josh i can't find a video about Taranis problems on your lists, but here is one for you. My firmware version is 2.2.3 I think that is the latest update. but when I choose new model on the first page I don't get the model type screen. Then in model setup, on model image I get "No bit maps on SD". They are there on the SD when i plug it into my PC. but not showing in Taranis Any ideas

@JoshuaBardwell 5 лет назад

Most likely your SD card needs to be replaced. Especially if it is the original SD card that came with the radio. They are kind of junk. On the PC, you see the files, but if you try to actually open one does it open?
