Troubles connecting X4R-SB to GCS

So, X4R is bound to Taranis fine (green bound light on steady on X4R) but have nothing in GCS. Went to testing/setup page in dRonin and the radio doesn't show up, no stick movements etc.

What have I missed?

jihlein

Have you set the RcvrPort to Sbus, cycled power, and then run the radio setup wizard?

grnd_flyr

Yes I have, when on RC Input screen of wizard, third page no throttle recognized when going through the wizard...

...thanks

Only other thing that comes to mind is are you on the correct set of pins on the X4R-SB? The connector should be on the set of pins closest to the receiver PWB? I made this mistake when going from the D4R-II to the X4R-SB, and had no response until I moved the connector.

If that doesn't help, maybe someone with direct experience with the Seppuku hardware will chime in, I haven't used that target hardware yet.

Thanks jihlein, hope so... ya it's connected like in the first pic (correct pins, yup done that too before )

X4R is talking fine with Taranis, just nothing getting through to the board... I dunno.

jihlein

Taking long shots now:

Try another pigtail between RC and FC?

Taranis is bound, but is it programmed to output the channels correctly?

grnd_flyr

pug398 :Thanks, but no... it's parked til I find out what I did wrong.

Which UART did you use?

jihlein :Taranis is bound, but is it programmed to output the channels correctly?
I'm completely new to dRonin so maybe I missed something here?... more info please

pug398

Hopefully you have this working now. I use X4R-SB with Seppuku and it has always worked fine

On the seppuku I have it on the port labeled "Receiver" on hardware tab and set for sbus. If it was another fc we were talking about then it would be labeled uart2.

Here's a link to the bin file from my Taranis. You could try loading this into your Taranis, then try the setup wizard again. That way you are working with a Taranis setup that's know to work with SBus. Let me know if this works, then I can guide you thru the specifics of what's included in this file.

jihlein : thanks a bunch! Wouldn't you know it, now Taranis is tired/charging, I'll try this in the morning. Really appreciate it... hoping

I probably should give you some details so it doesn't get more frustrating. I set this up in the TAER order, so:

Channel 1 Throttle
Channel 2 Aileron
Channel 3 Elevator
Channel 4 Rudder
Channel 5 Mode
Channel 6 Aux1
Channel 7 RSSI
Channel 8 Arm

Aux1 is the left side slider, arm is SB centered or down, and mode is a combination of SE, SG, and SF as follows:

Mode 1 SE back, SG back, SF back
Mode 2 SE centered, SG back, SF back
Mode 3 SE forward, SG back, SF back
Mode 4 SG centered, SF back, overrides SE
Mode 5 SG forward, SF back, overrides SE
Mode 6 SG forward overrides SE and SG.

SH, while not part of the channel groups, when pulled forward announces battery voltage if you have S Port and battery monitoring setup.

Hope this helps.

Also note more channels can be added, but I modified this from a D4R-II setup that only supports 8.

Thanks for trying to help guys. Gonna park it until I feel like getting in there and un-gooing the wires to check for a "bad connection" or something... it has to be something related to wiring the X4R & Seppu.

Pic shows the mess...

It is a shame to have it sitting. Other than wiring or bad rx the only other thing I have encountered is old artifacts can throw off the input wizard. For to check that go to firmware page and enter bootloader. On right in the partition browser right click on settings partition and erase. Boot board. Go to configuration page and manually fill in hardware tab and save. Go to Input tab and fill in rcvr type (sbus) for each used channel and save. Reboot board and then run input wizard and see if it detects inputs.

Hi,

Is that S.Port Wiring in the grafic on top correct? I trying to connect an X4R to this, binding is good. I get telemetry RxBt, RSSI, A2(?), SWR(?), so I can assume that taranis is getting telemtry. But no Sensors of the board, like heading, battery & stuff. I have FrSky SPort on UART6.

Anything else that I missed? Do I need another wiring, like this one: https://github.com/TauLabs/TauLabs/wiki/User-Guide:-FrSKY-S.PORT-telemetry

Thanks for help!

pug398

First which flight controller board do you have?

pug398

Doh! I guess since you mentioned uart6 I should figure it is a seppuku. The above diagram connection does not work as is. In the above diagram the s.port connection is to normal inverted s.port. This usually does not work with an F4 (without external converter) due to the design and you must tap the non inverted s.port signal off the X4R and feed it to the uart. For the uart(6) function you then select non inverted s.port. This type telemetry connection does work at the moment using Seppuku, X4R-SB and Taranis.

Check out this thread to see where to tap the non inverted s.port signal off X4R-SB. Then using the above connection diagram everything is same except s.port connection is made on back of rx.

Thank you! So the only wiring diagram for seppuku sport I could find is false. (I love that little thing making it possible to build a 200g Quad with full OSD and GPS, but a little more documentation outsides this videos would'nt be bad. So I try to get that to work non inverted...

erik23_de

Yep! Works like a charm now.
