java jssc調制解調器發送msg

Question

我想使用基於SIM900的單元調制解調器從Java/Netbeans發送文本消息。使用TeraTerm，我驗證了我可以使用帶有基本AT命令的調制解調器發送消息。以下代碼嘗試使用jssc發送消息。
我沒有收到錯誤，數據似乎寫入調制解調器，但我從來沒有收到短信。對於電話號碼，我已經嘗試了+，沒有。
在TeraTerm中，該號碼必須沒有+才能使用。已經嘗試了許多變體，並且使用了許多變體。仍然沒有取得進展。
我希望有人能看到我的方式的錯誤。

在此先感謝。 Doug

Answer 1

我能回答我上面提出的問題。下面的代碼工作。事件監聽器不需要在那裏。有幫助的主要變化是將新行和文件結尾定義爲字節「public static final Byte eof = 0x1A，nl = 0x0D;」然後將這些字節與命令「serialPort.writeByte（nl）;」分開寫入serialPort。我希望這可以幫助別人。

道格

PS：我寫了一個Java類，可以簡化使用JSSC發送代碼到SIM900，如果有人有興趣。
