android - java.io.IOException: [JSR82] accept: 接続が作成されていません (失敗または中止されました)

Question

Samsung GALAXY TAB 8.9 で BluetoothServerSocket を作成したいと考えています。(android 4.04) mmServerSocket.accept() を呼び出すと - スローされます:

「java.io.IOException: [JSR82] accept: 接続が作成されていません (失敗または中止されました)。」

私は多くの同様の記事を読みましたが、詳細な回答はありません。誰かが同様の問題を解決したか、この例外が何を意味するかを知っているかもしれません。

ありがとう。

Android の例「ChatExample」から取得したコード:
