I am using the UART profile (adafruit sample code) to send data between mobile phone and Arduino. However, I don&#39;t want my arduino to look for serial data at all times.

The nRF8001 SDK for Arduino does support an interrupt mode of operation using the settings in the lib_aci_init().</p> <p>aci_state.aci_pins.interface_is_interrupt and the aci_state.aci_pins.interrupt_number.</p><div style="clear:both;"></div>
