SFR_1 Red light flashing rapidly

[krempec2@hotmail.com]

My SFR is connected via sbus from a Flysky Fs-i6x and the red indicator light flashes quickly and at an uneven tempo. The green led flashes at the usual pace. If I turn SFR on without the transmitter on, the green light flashes first, then the blue flashes 3 times and then only the green continues to flash. If I then turn on the transmitter, the red flashes along with the green. I hope this is enough info for you to advise me . The end result is, no radio control functions are working thru the SFR except the daytime running lights do work and direct servos from the Rx work.

Hello,

My SFR is connected via sbus from a Flysky Fs-i6x and the red indicator light flashes quickly and at an uneven tempo. The green led flashes at the usual pace.

The green LED is not supposed to flash but should be permanently on when everything is in a normal, fully operational state.

Since the radio functions are not working I assume you have not been able to execute the Setup (teaching function) of the SFR-1, which would cause the green LED to flash slowly.

See also the table on page 50 of the manual.

If I turn SFR on without the transmitter on, the green light flashes first, then the blue flashes 3 times and then only the green continues to flash.

Good and normal practice: ALWAYS switch on the transmitter first. Switch off in reverse order, i.e. model first, then transmitter.

If I then turn on the transmitter, the red flashes along with the green. I hope this is enough info for you to advise me . The end result is, no radio control functions are working thru the SFR except the daytime running lights do work and direct servos from the Rx work.

Have you saved a project to the SD card and inserted the card into the SFR-1? If yes try another card.

If the new card works execute the Setup first in accordance with the manual. Make sure all SBUS or iBUS channels that will be used are assigned to a Prop-Channel in the Sound-Teacher, and that their respective input device (switch etc.) are all in neutral position during the Setup.

The red LED also flashes briefly when a sum signal (S-Bus, i-Bus or SUMD) is set in the Sound-Teacher, but no or incorrect signals arrive at Prop #6 on the SFR-1.

Have you activated a sum signal in your project in the Sound-Teacher?
What is connected to Prop #6?
Does your receiver output a sum signal?
