5340 power consumption

[poyuankung]

I have a few questions regarding the power consumption calculation of the network and application cores from the 5340:

1. With the assumption that all peripherals are turned off

   Can the power consumption results shown on the Online Power Profiler for Bluetooth LE webpage be understood as the combined power consumption of BLE communication and the network core domain?

2. When only maintaining the BLE connection without needing to update sensor readings, is it possible to put the application core into low power mode independently and have it be awakened by the network core when necessary to save power?

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

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.
