Cesar, It should work with caveats. Can you share the code that you are using to broadcast the message?
Here are the caveats: ? Broadcast message cannot be confirmed since you do not know who will receive it in advance ? UDP and the broadcast (multicast) methods are best effort and therefore packets may be lost although very unlikely on a local network with a modern switch Pat From: iotivity-dev-bounces at lists.iotivity.org [mailto:[email protected]] On Behalf Of Cesar Meira Sent: Tuesday, June 09, 2015 9:21 AM To: iotivity-dev at lists.iotivity.org Subject: [dev] Broadcast messages Hello all, I did a little 'hello world' application using IoTivity, sending a command to a device to turn a led on and off. The server runs in a Raspberry Pi and the client in a Linux notebook. The application did okay with this configuration. But then I tried to push a little forward and added another Raspberry Pi, with the exactly same code as the previous one. The objective was to test if the client could send "broadcast messages", and if similar devices could receive them. I set both RPis to register the endpoint "/red_led". My idea was that when the client sends a command "turn on" to endpoint "/red_led", both RPis would receive this command, but in the end only one of them received the message. So, is there a way to send a single broadcast message to "n" devices? Did I just misinterpreted the idea of the endpoint?
