Yes, that sounds correct to me. The application core in the Online power profiler is already in the lowest idle mode, you should be able to take the number from the calculator directly and add whatever current you estimate your application to use.

So when I simultaneously enable the sensor and the SPI interface while running the algorithm, I can calculate the system's power consumption by estimating the application core's power based on the execution speed, then directly adding the power consumption of the SPI interface, the sensor, and the BLE power consumption calculated from the webpage to estimate the total power consumption

Hello!

1. Yes this is the combined current consumption

2. No you can not turn off the application core. However, the application core itself does not really consume any current, since the application CPU will halt when there are no threads running. Put in another way, the application core will always return to the lowest power state automatically when not running any code.
