怎么引用 if(!expected_ble) /* Don't consider ble complete until CL_SM_BLE_SIMPLE_PAIRING_COMPLETE_IND */ { /* Send confirmation to main task */ pairing_Complete(thePairing, pairingSuccess, &cfm->bd_addr, TRUE); /* Allow ble connections only with paired device after br/edr pairing. */ thePairing->ble_permission = pairingBleOnlyPairedDevices; MessageSendLater(&thePairing->task, PAIRING_INTERNAL_LE_PAIR_TIMEOUT, NULL, D_SEC(appConfigLePairingDisableTimeout())); } }

这段代码是一个条件语句，如果`expected_ble`为假，则不认为蓝牙连接已经完成，直到收到`CL_SM_BLE_SIMPLE_PAIRING_COMPLETE_IND`事件。然后会发送确认给主任务，并设置`ble_permission`为仅允许与已配对设备建立蓝牙连接。最后会启动一个定时器，在一定时间后禁用LE配对功能。

你可以在你的代码中使用类似下面的方式引用这段代码：

if(!expected_ble) {
    pairing_Complete(thePairing, pairingSuccess, &cfm->bd_addr, TRUE);
    thePairing->ble_permission = pairingBleOnlyPairedDevices;
    MessageSendLater(&thePairing->task, PAIRING_INTERNAL_LE_PAIR_TIMEOUT, NULL, D_SEC(appConfigLePairingDisableTimeout()));
}
