Thank you for the reply and it seems interesting. is there any way i can stop the connection completely when not needed.

  • power_spi_disable(); // SPI

  • power_usart0_disable();// Serial (USART)

  • power_timer0_disable();// Timer 0

  • power_timer1_disable();// Timer 1

  • power_timer2_disable();// Timer 2
