CC1310: abnormal current during sleeping

Cherry Zhou

Part Number: CC1310

Hi team,

Here's an issue from the customer may need your help:

1) When go to sleep with Task_sleep, it can reach within 5uA. It has been set to sleep for 4 seconds, but a trip current of about 25uA occurs every other time (less than 2 seconds). How did this happen?

2) Also is it possible to avoid closing the serial port via UART_close() before going to sleep, and the Serial Assistant prints an 00? 

Thanks.

Best Regards,

Cherry

    Hi Cherry, 

    Please can you elaborate on the current consumption? Maybe some plot of current consumption. Is the application running some thing at a period of 2 seconds?

    And if you close UART, you cannot perform the UART_write().

    Regards,
