Hi Pavan,

It's likely reset by the Error module. Have you tried debugging the app to find out where the error is occurs? It could for instance be the call to APP_ERROR_HANDLER(p_event->data.error_communication); in APP_UART_COMMUNICATION_ERROR handler.

Hi All ,

I checked commenting UART and timer init function and also commented advertising_start functions, but still i am getting 33uA , when i tried to debug the code its going into hard reset so please advise how i can achieve required current with above application.

Thank you

Hello,

Both the TIMER and UART peripheral requires the system to keep the high frequency clock source active while in sleep and thus increase the idle current. Please try to remove initialization of the timer and UART and see if you get the excepted 1-2 uA floor current.
