I am using Speedybee 4in1 ESC BLheli32. Dhsot 600.
In the flight I am observing that ESC RPM is getting to zero many times. I donot see any issue in flight performance atleast not visually, not sure of logs.
Presumably you are using bdshot? That indicates a lot of corruption on the return path. What flight controller are you using?
Are you using the BLHeli ESC Telem UART is well? If so try disabling this to see if its interfering.
Which parameter is this? I an using ESC telemetry for notch filter, will that get affected?
This is SERIAL 5_PROTOCOL=16
and SERIAL5_Baud=115
So serial5_baud should be zero?
Try it - if you are using bdshot you don’t need it except for Voltage/Temp
I am getting temperature but not voltage with UART
I will try with this setting any way.
@andyp1per I tried setting
SERIAL5_BAUD=115
SERIAL5_PROTOCOL=-1
still this issue is present.
oh should i set serial5_baud to zero?
@andyp1per I set Serial5_baud=0 and Serial5_protocol=-1
i am still getting that spikes.
TBH I think you should look for hardware reasons here - e.g. interference in the dshot line. Try dshot300 and see if its any more reliable.
I tried that. But did not help. I have a log of hover test in which there is no such thing is happening.
