我正在致力於建立與藍牙客戶端的連接並打開用於數據傳輸的RFCOMM通道的簡單主機程序（C++/xcode/osx）。當我從BT客戶端向主機發送數據時，我將數據與隨機轉儲混合在一起，看起來是Bluetooth Audio Agent。是否有可能與OS X Bluetooth Audio Agent共享我的RFCOMM頻道？音頻數據使用IOBluetooth框架污染我的RFCOMM頻道
我的藍牙設備需要支持串行（SPP）和免提（HFP）配置文件。所以我堅信這個問題是圍繞着HFP或SCO配置文件來污染我的RFCOMM頻道和它的數據。有沒有辦法確保我只通過頻道收到我的數據？
這裏是我的項目的精簡版。當客戶端連接時，它開始回顯a的字母。主機應用程序打印從客戶端收到的內容，如果接收到的數據是a，則它也會記錄OK!\n。
