CC1110 wakeup wireless

Other Parts Discussed in Thread: CC1101, RF430F5978

Hi there,

Does anyone know if there is a way to put the cc1110 to sleep and, later on, wake it up with a radio signal rather than throught the interrupt pin?


Regards,
Francesco.

    Francesco, 

    To make that happen you will need to have software on the CC1110 that automatically wakes makes it wake up and "sniff" the RF environment for a signal periodically. This will in turn create the effect of "wake on RF". This consumes power of course, but because if the quick turn on from deep sleep of the CC1110, this should be manageable. 

    Here is a link to an appnote describing this senario:

    There is one alternative, and that is a new series of devices from our MSP430 group that has a built in Low Frequency RF receiver along with the high frequency CC1101 like radio from the CC1110.

    With this device you could be in complete "off" and then wake up the system with a low frequency RF signals (134kHz) or short range - inches.
