        console.log('notifyMissionsChanged deviceId: ${JSON.stringify(deviceId)}');
    },
    notifySnapshot: function (deviceId, mission) {
        console.log('notifySnapshot deviceId: ${JSON.stringify(deviceId)}');
        console.log('notifySnapshot mission: ${JSON.stringify(mission)}');
    },
    notifyNetDisconnect: function (deviceId, state) {
        console.log('notifyNetDisconnect deviceId: ${JSON.stringify(deviceId)}');
        console.log('notifyNetDisconnect state: ${JSON.stringify(state)}');
    }
};
distributedMissionManager.registerMissionListener(missionDeviceInfo, missionCallback);
