报错信息：transceive:fail:system internal error: Call connect() first

一链接标签，为什么会报错先调用connect

具体代码

ndef.connect({

success:function(resco){

// console.log(resco, 'connect')

console.log('nfc连卡成功：'+JSON.stringify(resco));

var arr = [0x30, 0x01];

var arrayBuffer = new Int8Array(arr).buffer;

nfca.transceive({

data: arrayBuffer,

complete(resup) {

console.log('resup:', resup)

}

})

},

})
