CC1110 Sleep mode and external interrupts

Geoffrey Hamon

Hi.

I use a CC1110 to receive audio data and everything is working fine.

Now I would like to put it in sleep mode to save energy.

So I would like it to awake when it receives RF data.

Problem is the RF interrupts seems to be considered as an internal interrupt while only external interrupts can awake CC1110 from PM3 mode.

Can you confirm ?

Thanks.

    Hi Geoffrey

    It is not possible to use RF interrupts to wake up the CC1110 from any power mode as the device must be in active mode for the radio to be able to enter RX. If you want to save power you can use PM2 and then use the SLEEP timer to wake up the device on a regular basic and then put the radio into RX mode for a given amount of time before going back to PM2.
