I'm using an nRF51822. Currently, I'm using the low power sleep mode. The device uses about 1.5 uA in sleep, which is great. The firmware wakes up the device every n minutes, advertises, and goes back to sleep if nothing pairs. If nothing paired, I wasted a bit of battery life coming out of sleep. Is there a way to wake on "activity on the antenna" just like the ability to wake on a GPIO interrupt?
Thanks, Osman
