CC2640R2F 功耗过高,需要优化哪些地方

Other Parts Discussed in Thread: CC2640R2F

开发环境:Code Composer Studio 8.3.0

SDK: simplelink_cc2640r2_sdk_2_30_00_28

工程: 蓝牙4.2 的simple_peripheral

硬件:CC2640R2F

修改的发射功率5db,发送间隔500ms,平均功耗为130uA;通过按键调用Power_shutdown(0, 0);切换到shutdown测试平均功耗60uA,按spec上在shutdown应该不大于1uA。

参考市面上其他CC2640R2F产品,发射功率5db,发送间隔500ms,平均功耗为60uA, Standby模式功耗5uA。

我们产品功耗在active与shutdown模式都高出60uA左右的功耗,已经有打开powersaving,shutdown模式应该只有gpio活动,需要如何排查漏电位置,优化哪些代码来降低功耗?

谢谢!
