BLHeli_32 telemetry only with auto telemetry on

Try the beta version of mission planner

Its beta only, now updating latest beta

If rpm is working and you are not using bdshot then it is working and must be some kind of GCS issue

But at least it should show in OSD, it is not showing in OSD as well, literally struggling for last 2-3days

I just loaded up a slim with the same firmware as you and connected to a F55A Pro II:

Parameters:

param-set.param (19.9 KB)

From where these values come
BATT_VOLT_PIN=10
BATT_CURR_PIN=11

They are the defaults for the board. I wiped the parameters and these were set automatically. If you set FORMAT_VERSION=0 you can reset all the parameters.

Many many thanks, while comparing with your parameters i got clue on BATT_VOLT_PIN and searched same and got to know from one of post by @xfacta Shawn that,
ESCs dont output current in the telemetry , the 4in1 has onboard analog current sensor.
so setting BATT_VOLT_PIN=10
BATT_CURR_PIN=11 it started showing voltage, but curret it shows incorrect.

If you look at my current calibration in the Chimera parameters above this is the result of a very careful calibration that will give accurate results above 3A but inaccurate results below that.

Thanks, are these PID values fine tuned?

For that frame, weight, battery, ESC and motor combination - yes
