我正在使用來自android網站的藍牙聊天示例應用程序。我想發送特定格式的長信息（在代碼中提到），並在另一端接收並在我的手機上顯示（HTC Desire）。我將進一步解析這個消息，提取一些東西並將其用於我的應用程序。藍牙的問題/問題HTC Desire的SPP配置文件會影響藍牙聊天應用程序嗎？
我無法接收上述消息中的所有字符（少數字符會被隨機省略）。是因爲藍牙套接字的InputStream「read」方法出現問題，或者藍牙SPP配置文件在HTC Desire或其他原因中存在錯誤和問題？我已經嘗試過InputStream是一個字節緩衝區，一個字符緩衝區，然後從緩衝區內容中創建一個字符串（使用普通的新字符串，StringBuilder和StringBuffer）。但不知何故，我無法在手機上以所需格式顯示整個消息。
任何幫助/建議，非常感謝。
謝謝您的時間
乾杯， 馬杜南丹
