let adapter = wx.getNFCAdapter()

    console.log('adapter',adapter)

    adapter.startDiscovery()

    var that = this

    adapter.startDiscovery({

      complete: function(cp){

        console.log("startDiscovery",cp)

      }

    })

    adapter.onDiscovered(function callback(res){

      console.log('onDiscovered',res)

      let ndef = adapter.getNdef(res)

      console.log('adapter.getNdef(res)',ndef)

      ndef.connect({success: function(ress) {

        console.log("ress", ress)

      }, fail: function(err){

        console.log("ndef", err)

      }, complete: function(cp){

        console.log("ndefcp",cp)

      }})

返回如下错误

ndef {errMsg: "connect:fail:not supported"}

ndefcp {errMsg: "connect:fail:not supported"}

请问这个是什么原因导致的呢
