One to Many WiFi stream

[rmick]

I am working a project where I want to do two-way radio style comms and your library is damn near perfect.

The i2S to TCP/IP works perfectly for point to point (1 to 1) communications, but I would like a one to many scenario, where one device can send out a message and all the other devices on that 'channel' can hear it. The current implementation does not allow this as it only sends to a single IP address.

Is this possible.

here are a couple of ideas

1. Use multicast.
2. allow multiple clients to connect (but I think this breaks the Arduino client class).

I started to work on the topic of streaming of audio data as well and suggest to use

• ESP-NOW
• UDP

I would also use it together with a CODEC

Hello everyone, Mr Schatzmann,
Has there been any progress in this development?
Using "streams-i2s-webserver_wav" as a reference, I´m looking for a way that allows several clients, through their browsers, to listen to the audio broadcast transmission of one ESP Wifi sender. Any suggestion on how to accomplish that?
Thanks.

I added the simple webserver just because I was getting tired of wiring up different modules to the processor and it was a convinient way to to test listen to the result. Even before the audio tools, I started to work on a (real) http server, but I never had the chance to complete it. I think it should not take too much effort to get this completed..

Here is the example sketch

Of cause the other suggested approaches will work as well...

You can also use the MultiOutput to send the audio to multiple destinations
