If you are using the regular and pro 2.4GHz XBee you don't need anything close to 1A. The hardware pin sleep is so low power that turning it off makes little sense. Just my two cents from the guy who builds low power hacking drones. On Dec 31, 2014 4:36 AM, "Kevin D'Souza" wrote: > I have an ap

The PRUSS don't cause any CPU usage. You can reduce CPU usage by adding a nsleep() call to your while loop. Anyway, the max. speed of pulling the GPIO state (as in your while loop) is limited to approx. 140 kHz. An alternative is to configure a GPIO interrupt 1. Map an interrupt to any chann
