点击一个按钮，发送3个字节到指定嵌入式中，用下列方式，用wireshark抓包，发现发出去的字节为0，想请教各位大佬，下列代码设计是不是有问题？

clickMe: function () {

if (typeof wx.createUDPSocket === 'function') {

let that = this

const udp = wx.createUDPSocket()

var arrayBuffer = new Uint8Array([11, 22, 33])

let myPort = udp.bind()

console.log('分配的端口是：', myPort)

console.log(arrayBuffer)

udp.send({

address: '192.168.1.101',

port: 5001,

data: [0x1,0x2,0x3],

offset:0,

len: 3

})

}

}
