CC2652P: Power consumption issue

Part Number: CC2652P
Other Parts Discussed in Thread: SYSCONFIG, Z-STACK

Hi, 

We are making an end device application what uses significantly more power on battery than the values listed in this document: https://www.ti.com/lit/an/swra595/swra595.pdf . The application is based on the LP-CC2652P2 zed_sw example. There are a couple of Button_setCallback and GPIO_setCallback functions used in the current code what then unlock appSemHandle (ZStack process loop) when called. Should there be a significant improvement in power usage expected by removing Button/GPIO callbacks and moving the handling of those into the Sensor Controller? Is there anything else what needs to be thought of while debugging this scenario? Thank you,

Daniel

    Hi Daniel,

    Please refer to SWRA625 and the Power Configuration section of the Z-Stack User's Guide.  The Buttons/GPIO are not your main concern and are unrelated to the Sensor Controller.  You should be at least removing the BOARD_DISPLAY_USE_UART Predefined Symbol from the Project Properties -> CCS Build -> Arm Compiler window, or furthermore setting CUI_DISABLE from the same location and adding Z_POWER_TEST and a POWER_TEST_* mode as well.  Please also refer to the Sysconfig -> Z-Stack module for poll rate and TX power settings.  If this does not resolve the issue then please provide details about the exact power consumption recorded and how it is measured from the device.

    Regards,
