    EZ PRoC Power Modes are not working

    josu.olmeda

      Hi to all,

         

      I have done a simple program for testing the consumption of the EZ PRoC Module (CYBLE-022001-00). With that code the outcomes are as follows:

         

      - Normal Mode: 12.47mA

         

      - Deep Sleep: 1.48mA

         

      - Hibernate: 0.24mA

         

      The measures have been done according to the recommendations on the page 85, BLE Pioner Kit Guide for CY8CKIT-042-BLE documentation.

         

      The code is attached. It uses Timer1 for create an interruption 5 seconds after starting. When the interruption happens, the module entries on one of the low power mode: or Deep Sleep or Hibernate, according to the mode the user has selected before the compilation and flashing.

         

      According to the documentation (EZ-BLE PRoC Module, page 13), values should be near to the next:

         

      - Normal Mode: 13.14mA

         

      - Deep Sleep: 1.3uA

         

      - Hibernate: 150nA

         

      Does anyone could tell me why the values I have measured for low power are so far than it should be expected?

         

      In advance, I appreciate a lot any suggestion.
