我已經購買了Arduino UNO WIFI板（http://www.arduino.org/products/boards/arduino-uno-wifi），但無法正常工作。Arduino UNO WIFI無法正常工作
如果它從http://www.arduino.org/learning/tutorials/boards-tutorials/restserver-and-restclient 嘗試以下示例，每個GET請求的答案例如arduino.local/arduino/analog/2 是「〜」。內的WiFi的控制檯我發現只有怪字符，如「~~」，並在調試日誌我發現：
746211> ARDUINO REST content: /arduino/digital/13/1
788705> ARDUINO REST content: /arduino/analog/2
我的固件更新到2016年3月18日 - 79f152c，但沒有改變。
RestServer代碼：
/*
RestServer.ino
Arduino Uno WiFi Ciao example
This example for the Arduino Uno WiFi shows how to use the
Ciao 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)
