I'm working on a wearable XLP (extremely low power) device that uses Bluetooth Low Energy to communicate with an iPhone app. As the device is currently a prototype, I'm working with Adafruit's nRF8001 BLE breakout board, which breaks out the active signal pin of the nRF8001 chip. I want to use this pin to wake up the processor (ATTINY84A) when a message is received, but it's disabled by default. Does anyone know how to enable it? Bonus points if you know how to do it by modifying the the Adafruit nRF8001 library...
