High idle current on NRF52832 app_template example

[navaneeth]

Hi,

I am using NRF52832 with SDK 15.3 and SD 132 on our custom board ( VDD 1.96V ). I started with with the ble_app_template example for our application. Upon measuring current it was seen that even if its not advertising the current consumption was quite high ~600uA. To understand which part was taking the high current , I tried commenting out each of the initialisations in the main and it looks like after timers_init(); the current consumption increases.

Please help in debugging this issue as our application is meant for low power usage.

Thanks

Hi, 

Please make sure debug logging over UART is disabled in your project (NRF_LOG_BACKEND_UART_ENABLED option in sdk_config.h).

Hi,

It is already disabled.

Hi,

Have you made any other changes to the example project? Also, does it work as expected, aside from the high floor current? I get ~2.3 uA when I turn off logging.

Hi,

I am using internal RC osc for low freq instead of a 32.768kHz external crystal.

Hi,

could you upload your .hex so I can try it here?
