Salva ragazzi...premetto che prima di scrivere qui ho letto altri Topic ma nn sono riuscito a capire come risolvere il problema. allora io sto facendo delle prove con il file example Bridge con arduino Yun. quando mi ritrovo a mettere nel browser: http://myArduinoYun.local/arduino/digital/13, esce :
Could not connect to YunServer 146 Connection refused.
l'opzione Rest è impostata su Open, ho sostituito server.listenOnLocalhost(); con server.noListenOnLocalhost(); ho spento e riacceso arduino. non so cosa fare...datemi una dritta per favore.
/*
Arduino Yún Bridge example
This example for the Arduino Yún shows how to use the
Bridge library to access the digital and analog pins
on the board through REST calls. It demonstrates how
you can create your own API when using REST style
calls through the browser.
Possible commands created in this shetch:
* "/arduino/digital/13" -> digitalRead(13)
* "/arduino/digital/13/1" -> digitalWrite(13, HIGH)
* "/arduino/analog/2/123" -> analogWrite(2, 123)
* "/arduino/analog/2" -> analogRead(2)
* "/arduino/mode/13/input" -> pinMode(13, INPUT)
* "/arduino/mode/13/output" -> pinMode(13, OUTPUT)
