Hello Paul
Thanks, good to know I am not the only one with this issue. Except, my board had this error not from the beginning, it started after about 20 flights. After that, it often still initialized after a few times unplugging and plugging the battery again. But it seemed to get worse, until i found out the trick with the power bank. Did you or David found out what exactly the problem was?
Thanks, Michael
mgParticipantThe next morning the problem was back again. When plugging in the battery i get a “FAILURE_MISSING_ACC” beeping. Which as far as i have read could be missing gyro as well.
For now, when i go flying i just plug in a usb power bank before plugging in the battery, then unplug the power bank, then i can fly… this works, but if anybody knows the cause or even better, a solution for the problem i would be really thankful.
Thanks, Michael
mgParticipantAfter cleaning the board/fc, everything works like a charm again 🙂
mgParticipantI just recorded the beep sequence and saw, it were 5 short and 2 long beeps. Shame on me… this is actually an error code, discussed in here:
https://github.com/cleanflight/cleanflight/issues/2023typedef enum {
FAILURE_DEVELOPER = 0,
FAILURE_MISSING_ACC,
FAILURE_ACC_INIT,
FAILURE_ACC_INCOMPATIBLE,
FAILURE_INVALID_EEPROM_CONTENTS,
FAILURE_FLASH_WRITE_FAILED,
FAILURE_GYRO_INIT_FAILED
} failureMode_e;Add one to the starting number (zero in this case) and your two flashes mean FAILURE_MISSING_ACC. Cleanflight does not see the gyro chip, so unfortunately, your board is probably broken.
In my case, then, it means: “Accelerometer/gyro sensor is missing” too… but just sometimes, actually most times when i do not connect usb-power to the board before connecting the battery. And it seems to always be there when i do connect usb-power.
Any idea?
I will unscrew the Frame / FC and look if there is some visible damage or so.
mgParticipantThanks. I have found that but 4 short and 2 long beeps is not listed there. It would be something like: 5,5,5,5,5,5,5,15,15,15,15, which i can’t find.

Couldn’t Ardupilot being run on an F3FC?
– damn question?
– no way?
– way to much work to do so?mgParticipantHello everybody
I am using a Spektrum Transmitter and just bought a orange receiver for it because i wanted telemetry.
Unfortunately i did not read swissfreak’s post clear enough:
In order to get telemetry to Spektrum, you’d have to use a Spektrum telemetry module and plug that into your receiver. It would not interface with cleanflight.
I missed the point with not interfacing 🙁
So i wonder why is that. Is it because “nobody” (or at least no developer) uses Spektrum anymore and supporting it is not worth the effort implementing it? Is the protocol proprietary and not documented? Or are there hardware reasons for the lack of support?
My second question is if it would be possible to connect the F3FC inbuilt current sensor somehow to my receivers telemetry port to get out current and energy consumed (A and Ah)?
Thanks,
Michael -
