SBus fails on teach/setup

Beitrag von jimfity@gmail.com »

This is my first time using a SFR-1 and SBus. The receivers[1] I have only have a SBus out put there is no normal PWM connections. When connected and the SFR-1 is configured to use SBus all props can be map to channels on the receiver. These work like a dream. Even using the "start diagnosis" tool the inputs on the prop 1 can be seen but there is no prop 1 action.

When trying to do the teach setup I get a quick red led flash as the 3 blue led flashes are happening on the throttle down stage. I have tried multiple of these SBus receivers all give the same issue. Software being used is 1.40b.

I took a 2 channel PWM receiver from a different model to check if the SFR-1 was working as expected. And it does, with the PWM cable plugged into X2/1 the motor and sound works.

What can I do to get the SBus receiver to work?
What debug information can I get to help work out what is going wrong?

Hello,

when you take the SFR-1 into use the very first time (or when replacing the SD card) you must first transfer a project via the SD card, i.e. put the SD card into the PC, configure your project with the Sound-Teacher (ST), save to the PC as backup and then to the SD card using the appropiate icon or menu option. When done close the ST and eject the SD card via Windows.

Now put the SD card into the SFR and repeat the setup.

Once the SFR-1 is up and running you may use the data cable to change the configuration or peform a diagnosis.

I have done that. The set up works with an non Sbus receiver. Sounds, lights and drive motor all work. The problem is when switched to SBus prop 1 does not work any more and the teach function fails.

How can I debug this issue?

Hello,

please upload the project file (*.sfr) with the SBUS configuration.

Sure no problem.

Attached file is simplest I could make it. Both props 2 & 3 work as expected.
Prop 1 does not trigger any motor action.

Hello Jim,

thanks, the configuration looks ok.

Please try swapping "S-BUS / SUMD Ch. 2" with "S-BUS / SUMD Ch. 4", so that Channel 4 becomes the throttle - just for the purpose of testing. Can you now perform the setup?

Also please let me know the status of the LEDs from the time you power on the SFR-1 and when you perform the setup. Please specify if the LEDs are solid, flashing slow or flashing fast (for each LED).

I tried swapping the channels. This gave the same outcome.

This is how the LEDs acted during the teach.
  • SFR-1 on (not in teach mode) Green = Slow flash, Red = off, Blue = Fast flash
  • Teach mode active Green = Fast flash, Red = off, Blue = off
  • Throttle up for 2 seconds
  • Throttle return to centre Green = off, Red = off, Blue = 2 slow blinks
  • Next teach stage Green = Fast flash, Red = off, Blue = solid on
  • Throttle down for 2 seconds
  • Throttle return to centre Green = off, Red = 1 blink on last blue blink, Blue = 3 slow blink
  • Return back to on mode Green = Slow flash, Red = off, Blue = Fast flash

Please record a diagnosis (via data cable or onto SD card) while doing the setup process. Then upload the diagnosis here.

Sure no problem.

I recorded it twice using the cable.

According to the diagnosis, the setup process is being performed correctly. Neutral value, maximum value and minimum value are read in and saved correctly.

I can't explain why the red LED blinks once in your case in the last step.

But according to the diagnostics, everything should now be working correctly. What exactly isn't working now?
