    how to reduce the power consumption when use puart ?

    janush

      chip : BCM20736S

      SDK : 2.1.1

      reference app : uart_firmware_upgrade

       

      1. I need BLE to keep in ADV that is normal state. 

      2. when connection_up, I need turn on paurt.

      3. when connection_down, I need turn off puart.

      4. when ws_upgrade_uart_device_lpm_queriable return -1 (connection_down),

          the power consumption will down

      5. when ws_upgrade_uart_device_lpm_queriable return 0 (connection_up),

          and then re-enable puart but the interrupt of Rx won't be occurred
