Wake over WiFi

Jacob Jorvang

Is it possible to wake the CC3000 from sub-uA low-power mode over WiFi, or does it need to wake up periodically to check if someone needs it?

Hi Jacob.

You can find more about this subject here:

In the sub uA mode the part is in shutdown, meaning the receiver is disabled.

Hi Anders

Thanks for the link.

I guess I will have to have it periodically woken up. There are ways to wake a module without it being powered on, but it requires additional low-power circuitry to detect and decode the wake-up signal. A clever design has just been proposed by Kondo, et el (Energy-efficient WLAN with on-demand AP wake-up using IEEE 802.11 frame length modulation), but I think it would have to be mass produced to make economical sense, at least for my application.
