WINCE藍牙如何檢測被其他設備發起配對請求

主要使用以下接口：

BthSetSecurityUI  設置收到配對請求後，可以收到消息的事件；設置超時時間

BthGetPINRequest 獲得與該設備請求配對的設備地址

BthSetPIN/BthRefusePINRequest 設置PIN/拒絕對方的配對請求

主要是BthSetSecurityUI 的使用：

第一個參數爲事件，當藍牙設備收到其他設備的配對請求，此事件有信號；第二個參數爲超時時間，當第一個參數事件變爲有信號時，需要在這個時間範圍內調用BthGetPINRequest才能獲得對方設備的地址；第三個參數也爲超時時間，只有在這個時間內調用BthSetPIN設置PIN碼，才OK

附加代碼，主要是通過線程來監測其他設備的配對請求

#define ADIO_BTSERVICE_STORE_TO   3000
#define ADIO_BTSERVICE_USER_TO  60000
#define ADIO_BTSERVICE_SLEEP  5000
