Hello,

The feature supported on CC3351 is the Wake on Wireless LAN. This is based off of the linux kernel's implementation of the same feature.

Ok, thanks you for you support.

If my work scenario is:

My board is working normally and connected to the router hotspot using CC3351, which can connect to the WAN.

I send network packets to the board through a public network server (such as a cloud server).

Can CC3351 detect network packets and wake up the host while putting the board and CC3351 into sleep mode?

Yes, that should be possible. You would need to build a packet from the cloud server that would meet the requirements of matching a packet filter set by 'iw wlan0 wowlan pattern ...'

You can learn about the packet filtering from our documentation here:
