与BluetoothLeGatt绑定

Question

正在修改BluetoothLeGatt以发出Jaalee信标的声音。能够连接到信标，但不能绑定以写出信标的特征。借助NRF Connect和BLE扫描仪，我能够将密码特征写入绑定并将特征写入声音。可以肯定的是，我修改后的BluetoothLeGatt的问题在于它没有将密码0x666666写到信标，因为如果我第一次与NFR connect或BLE扫描仪绑定，我可以使信标在修改后的BluetoothLeGatt上发出声音。

我尝试了不同形式的密码fff 666666。

   // service sound
public void onClickWrite(View v){
    if(mBluetoothLeService != null) {
        mBluetoothLeService.writeCustomCharacteristic(0x02);
    }
}
// service login
public void onClickLogin(View v){
    if(mBluetoothLeService != null) {
        mBluetoothLeService.LoginCustomCharacteristic(0x666666);
    }
}
// activity sound
public void writeCustomCharacteristic(int value) {
    if (mBluetoothAdapter == null || mBluetoothGatt == null) {
        Log.w(TAG, "BluetoothAdapter not initialized");
        return;
    }
    /*check if the service is available on the device*/
    BluetoothGattService mCustomService = mBluetoothGatt.getService(UUID.fromString("00001802-0000-1000-8000-00805f9b34fb"));
    if(mCustomService == null){
        Log.w(TAG, "Custom BLE Service not found");
        return;
    }
    /*get the read characteristic from the service*/
    BluetoothGattCharacteristic mWriteCharacteristic = mCustomService.getCharacteristic(UUID.fromString("00002a06-0000-1000-8000-00805f9b34fb"));
    mWriteCharacteristic.setValue(value,android.bluetooth.BluetoothGattCharacteristic.FORMAT_UINT8,0);
    if(mBluetoothGatt.writeCharacteristic(mWriteCharacteristic) == false){
        Log.w(TAG, "Failed to write characteristic");
    }
}        
// activity login 
public void LoginCustomCharacteristic(int value) {
    if (mBluetoothAdapter == null || mBluetoothGatt == null) {
        Log.w(TAG, "BluetoothAdapter not initialized");
        return;
    }
    /*check if the service is available on the device*/
    BluetoothGattService mCustomService = mBluetoothGatt.getService(UUID.fromString("0000fff0-0000-1000-8000-00805f9b34fb"));
    if(mCustomService == null){
        Log.w(TAG, "Custom BLE Service not found");
        return;
    }
/*get the read characteristic from the service*/
BluetoothGattCharacteristic mWriteCharacteristic = mCustomService.getCharacteristic(UUID.fromString("0000fff1-0000-1000-8000-00805f9b34fb"));    
mWriteCharacteristic.setValue(value,android.bluetooth.BluetoothGattCharacteristic.FORMAT_UINT8,0);

    if(mBluetoothGatt.writeCharacteristic(mWriteCharacteristic) == false){
        Log.w(TAG, "Failed to write characteristic");
    }
