application is not running on external power

[karoun]

Hello,

I am running an application on nrf52840DK. It is using uart service to send a sensor data through BLE to Uart servic on smartphone. I want to measure the current consumption of application but it seems that the application is not running on external power. I saw in some discussion on devzone that suggesting to disable the APP_UART_ENABLED on adk_config but device stop advertising after disabling the APP_UART_ENABLED . Can you please help me on this?

Best regards,

Karoun

How do you determine that the application is not running?

Is the chip powered? Clearly, nothing will run if the chip has no power!

When application start running the LED 1 on board start blinking. But with external power the device hanging(one led blink). other applications for example blinky is working fine with external power.

What do you mean by "external power" ? Please describe how you have configured your nRF52840 DK. Hardware description of the nRF52840 DK can be found here.
