Hi Supporter!

Could you please guide me how to send packet data one-to-many communication over an IP network?

An example for multicast

I use example network_terminal to send a tcp/ip pack between two boards cc3220sf. But I can't find how to send data with multicast and how to init.

Can you help me?

Thank you!

Vu.

    Nguyen,

    Unfortunately we do not have any example projects available to demostrate multicast. My suggestion would to  do the following:

    1. Take a look at our host driver documentation in the sdk (Specifically the Socket functions). Essentially what you will do is open a UDP socket, add membership to the multicast group, and then send or recieve from each device.

    2. You can view our wifi_audio_app example in the CC3200 SDK. This should how to configure multicast, but you'll need to do the translation to the new host driver.

    Hope that helps,

    Vince
