標題: arduino ethernet 問題
大家好我的arduino ethernet有個很奇怪的問題
我在測試的時候 arduino連usb2.0 serial board連電腦
送出http request 是沒有問題(server可以接收到)
等我要上線時我把usb2.0 serial board拔掉
改採用adapter提供的電源
這時候arduino 似乎就不會送出request 給server端
明明我甚麼都沒變壓
請問大家知道這是為什麼嗎

usb2.0 serial board 是什麼?

「送出http request 是沒有問題(server可以接收到)」
「Arduino 似乎就不會送出request 給server端」
上列兩項你是如何驗證的呢?有沒有什麼輸出結果或畫面?

How about posting your code?

Hi Coopermaa 大大你好:
那個應該是叫 USB 2 Serial Light.
負責arduino Ethernet 接電腦的板子

回復一下:
我arduino送出http request , server端接收到 server會有log出來(我是用java servlet)

問題在於我只要接電腦 Arduino會乖乖地送出訊號給server
但是如果不接電腦只接網路線 arduino就很像是斷了線送不出request
實在想不出到底是甚麼原因

以下是arduino的code
