I would like to host a web page from a RPi that has websocket controls that update in 'real time' such as a slider that transmits its value as you move it. I then want to broadcast the values to several ESP8266 modules (~10) running Arduino via Wi-Fi. I would like to have a payload data rate of ~10 bytes/packet x 30Hz = 300 Bytes/s.
What type of connection should I use for the Pi to the ESP8266s? I think MQTT is too slow for this?
