How VESCTOOL Determines the foc_sensor_mode

[MelvinWarnet]

My goal is to create a Python script with the same functionality as the VESCTOOL setupwizardfoc. I am using the Pyvesc library to encode and decode messages for the VESC. I send the COMM_DETECT_APPLY_ALL_FOC message, the motor runs correctly, and I receive a response corresponding to the COMM_GET_MCCONF message. So far, I am following the same logic that I observed in the VESCTOOL source code.

What I do not understand is the logic VESCTOOL uses to analyze the mcconf of the VESC and deduce the foc_sensor_mode. In the COMM_GET_MCCONF message that I receive, there are many parameters, as you can see in the text below. However, the only parameter whose value changes depending on the Sensor mode in the FOC tab of VESCTOOL is the following:

foc_duty_dowmramp_ki: 0.0 in sensorless
foc_duty_dowmramp_ki: 2.802596928649634e-45 in hall sensor
foc_duty_dowmramp_ki: 1.401298464324817e-45 in encoder
