B4J Question [server] show state of button from raspberry.

[jayel]

Hello,

Many examples show how you can do ajax posts when for example you push a html button on a page.

But how can I force ajax posts when the input of a raspberry pi (with piface 2) state changes?
How can I force a ajax post with B4J code ?

Don't use ajax.

You should either user websockets or MQTT.
