CC2340 low power problem

I have successfully built the SIMPLE_peripheral project of CC2340, but after I remove the UART2 peripheral through the SYSCFG configuration interface, I measure its power consumption, and the average power consumption is about 1.3mA, which is abnormal. I refer to the GPIOStandby routine, and the power consumption is about 1.5μA. How can I reduce the power consumption of the Simple_peripheral project?It is necessary to verify the power consumption of the CC2340 for 1 second broadcast interval so that it can be demonstrated to customers. Here are some screenshots of the problems.

    Hi,

    Thank you for your interest for the CC2340.

    The power consumption you have measured is expected given limitations in the software. Actually, the software does not enable the device to go to standby mode hence a pretty high power consumption. Our teams are working to improve the software implementation and reach a much lower power consumption.

    Note for other readers: The results presented in this threads are obtained with CC2340 engineering material, with SDK 6.10.xx.xx. The power consumption of the device will be optimized by the official release date of the CC2340.

    Best regards,
