    Power measurement in PRoc BLE

    shafy.s

      Hi,

         

      I am trying to measure power consumption of a PRoc CYBL10563 board by running the Heart Rate sensor example. The avg current measurement using a DMM when the advertising interval is 1000 ms is around 500 uA, which seems to high.  I know measurement using DMM is not very accurate, but still expecting lower values.

         

      In the main loop of the program, i can see the LowPowerImplementation() function call which tries to enter deep sleep mode.  Please advise any other API need to be called to enter the deep sleep mode.

         

      I am using CY8CKIT-042 for the testing

         

       

         

      Thanks

          Disabling debug mode by setting the swd pins to GPIO saves a lot of power. Also control the pin states that may drive some external hw.
