Hi all,

I am relatively new to the hobby, and therefore to this forum.

Now last week I was trying stuff out in Betaflight to improve my flight experience (ofc in combination with research).

While I was doing that, I (accidentally?) changed the PID loop frequency from 4khz to 8khz. Immediately after saving the change, I got kicked out of betaflight and I can no longer connect the flightcontroller (GEP-12A-F4 AIO) to betaflight anymore.

Tried to search for a solution online but couldn't find a similar case that came up with a solution.
So here I am, hoping someone can help me solve this dumb mistake of mine.

Cheerio,

its likely you changed something else other than the PID loop setting, as that shouldnt break your install. I would put your FC into BOOT/DFU mode using the boot button, and reflash your version of betaflight.

If you'd like, post your model of FC and a pic of the wiring for us to look over as well.

EDIT: welcome to the forum!

Thank you for your reply.

Perhaps, but it was after changing the PID loop frequency that the FC kicked me out. So I figured that it must be related.
However, I was flying happily just a few minutes before I changed 'something' in the settings. So the wiring is not the problem (I think).

To give you more information, Betaflight does recognize my drone and sometimes I get through for a short time. Although I cannot make any changes as it doesn't respond anymore to the save and reboot button.
Most of the times I just get the message 'waiting for data....'.

I have a geprc P16 HD and I am not sure about the model of the FC.

Going to follow your advice and try the Boot method to see if I can reflash it!

Lets see!

… try another usb cable (make sure it is a data cable) place the quad on a stable flat surface.. plug it in, if betaflight recognizes / connects.. DONT TOUCH it!! See if u get full connection (all tabs working)… if so.. THEN manipulate the quad.. see if it responds correctly.. and if connection gets lost..

@matt0725: thanks for your help! I now have a working FC again.

This might help others in the future.

Putting the FC in boot/DFU mode and re-flashing it helped me to quickly lower the PID loop frequency and everything was back to normal.

I think what happened is that by increasing the PID loop frequency the CPU load was to high for the FC to process everything (>80%). Probably a result of all the settings of the FC and not only the PID loop frequency.

By lowering the frequency the CPU load is now <30-40% and everything is responding perfectly.

Cheers,

you might need to reflash the fc, bidirectional dshot on 8k could cause excessive cpu load to no function.
i had this on f3 targets with betaflight performance edition
