Question

使用nodejs在乐山lwm2m服务器中的Iam新手，我的问题是，当我在同一台服务器上同时运行所有 lwm2m引导服务器， lwm2m服务器和 nodejs客户端时，一切正常，但是我希望分别在不同服务器上的 lwm2m引导服务器和 lwm2m服务器，会发生以下错误：

     Error during bootstrap write of security instance LwM2mObjectInstance [id=1, resources={0=LwM2mSingleResource [id=0, value=coap://serverIP:5683, type=STRING], 1=LwM2mSingleResource [id=1, value=false, type=BOOLEAN], 2=LwM2mSingleResource [id=2, value=3, type=INTEGER], 3=LwM2mSingleResource [id=3, value=[B@14f84ed2, type=OPAQUE], 4=LwM2mSingleResource [id=4, value=[B@26dd8bf3, type=OPAQUE], 5=LwM2mSingleResource [id=5, value=[B@45b87cb1, type=OPAQUE], 6=LwM2mSingleResource [id=6, value=3, type=INTEGER], 7=LwM2mSingleResource [id=7, value=[B@48ffc30a, type=OPAQUE], 8=LwM2mSingleResource [id=8, value=[B@1e279a19, type=OPAQUE], 9=LwM2mSingleResource [id=9, value=, type=STRING], 10=LwM2mSingleResource [id=10, value=123, type=INTEGER], 11=LwM2mSingleResource [id=11, value=1, type=INTEGER], 12=LwM2mSingleResource [id=12, value=0, type=INTEGER]}] on mahsa

我为引导服务器运行以下命令： java -jar leshan-bsserver-demo-1.0.0-M9-jar-with-dependencies.jar -lp 5681 -slp 5682 -wp 8000 而这个用于lwm2m服务器：java -jar leshan-server-demo-1.0.0-M9-jar-with-dependencies.jar -lp 5683 -slp 5684 -wp 8080

我的客户代码是：

var CoapNode=require('coap-node'),
SmartObject=require('smartobject');

const DEVICE_NAME = "client1";
const SERVER_IP = "serverIP";
const SERVER_PORT = 5681;

var so = new SmartObject();

// initialize your Resources
// oid = 'temperature', iid = 0
so.init('temperature', 0, {
_state: {
    tempVal: 26
 },
sensorValue: {
read: function (cb) {
console.log('read is called!');
cb(null, this._state.tempVal);},
write: function (val, cb) {
console.log('write is called: ' 
+val);
this._state.tempVal = val;
cb(null, this._state.tempVal);
    }
},
units: 'cel'
});

var coapNode = new 
CoapNode(DEVICE_NAME, so, { 
lifetime: 300 });

coapNode.on('bootstrapped', 
function (data) {
console.log('bootstrapped');
coapNode.registerAllCfg(function 
(err, rsp) {
    console.log(rsp);
});
});

coapNode.on('registered',function(){
setInterval(function () {
    var analogVal = ((Math.random() 
*(30-25+1))+25).toFixed(1);
    so.write('temperature',0, 
'sensorValue',analogVal,function(err,val){
        if (!err)
            console.log("timer 
value written: " + val);
        else
            console.log("timer 
write error: " + err);
    });
}, 10 * 1000);
});


coapNode.on('deregistered', 
function (msg) {
console.log('deregistered');
});

coapNode.on('offline', function 
(msg) {
console.log('offline');
});

coapNode.on('reconnect', function 
(msg) {
console.log('reconnect');
});

coapNode.on('error', function (err) 
{
console.log(err);
});

coapNode.bootstrap(SERVER_IP, 
SERVER_PORT, function (err, rsp) {
if(err) {
    console.log(rsp);
} else {
    console.log(rsp);
}
});
