SmartConfig配网小程序开发

操作场景

基本原理

设备进入 Wi-Fi 混杂模式（promiscuous mode）以监听捕获周围的 Wi-Fi 报文。由于设备暂未联网，且 Wi-Fi 网络的数据帧已通过加密，设备无法获取 payload 的内容，但可以获取报文的某些特征数据，例如每个报文的长度。同时对于某些数据帧，例如 UDP 的广播包或多播包，其报文的帧头结构比较固定，较容易识别。
此时在手机 App 或者小程序侧，即可通过发送 UDP 的广播包或多播包，并利用报文的特征，例如长度变化进行编码。
将目标 Wi-Fi 路由器的 SSID/PSW 字符以约定的编码方式发送出去，设备端在捕获到 UDP 报文后，按约定的方式进行解码，即可得到目标 Wi-Fi 路由器的相关信息并进行联网。

设备绑定流程

SmartConfig 方式配网，每个厂商的编码方式和报文选择上有自己的协议，对于 ESP8266，采用的协议是乐鑫 ESP-TOUCH协议。

基于该协议，设备端在连接 Wi-Fi 路由器成功后，将会告知手机端自己的 IP 地址。目前本小程序已支持采用 ESP-TOUCH 协议进行 SmartConfig 配网。
SmartConfig 方式配网及设备绑定的示例流程图如下：
为了减轻局域网络负担，本实现采用组播方式，组播地址生成代码如下：

  let _count = 0function getTargetHostname() {_count %= 100_count++return `234.${_count}.${_count}.${_count}`};

乐鑫ESPTOUCH编码原理时将ssid字符串转成ASCII编码数据流，加入CRC，AP的MAC地址本身就是16进制数据无需转换ASCII码，IP地址转整型数据。最终生成的数据流转换为uint16后，利用uint16去调制udp数据包长度代码如下：

function toDatumCode(apSsid, apBssid, apPassword, ipAddress, isSsidHidden = false) {let totalXor = 0const apSsidRaw = bufferFromString(apSsid)const apSsidCrc = crcBuffer(apSsidRaw)const apSsidLen = apSsidRaw.lengthconst apBssidCrc = crcBuffer(toRawBssid(apBssid))const apPwdRaw = bufferFromString(apPassword)const apPwdLen = apPwdRaw.lengthconst rawIp = toRawIpv4(ipAddress)const ipLen = rawIp.lengthconst EXTRA_HEAD_LEN = 5const totalLen = (EXTRA_HEAD_LEN + ipLen + apPwdLen + apSsidLen)const dataCodes = []const addDataCode = (v, index) => {dataCodes.push(toDataCodes(v, index))totalXor ^= v}let index = 0addDataCode(totalLen, index++)addDataCode(apPwdLen, index++)addDataCode(apSsidCrc, index++)addDataCode(apBssidCrc, index++)const totalXorIndex = index // save totalXor indexdataCodes.push(null)  // to fill totalXorindex++for (let i = 0; i < ipLen; i++) {addDataCode(rawIp[i], index++)}for (let i = 0; i < apPwdLen; i++) {addDataCode(apPwdRaw[i], index++)}for (let i = 0; i < apSsidRaw.length; i++) {totalXor ^= apSsidRaw[i]}if (isSsidHidden) {for (let i = 0; i < apSsidRaw.length; i++) {dataCodes.push(toDataCodes(apSsidRaw[i], index++))}}dataCodes[totalXorIndex] = toDataCodes(totalXor, totalXorIndex)const bytes = []for (const dataCode of dataCodes) {for (const b of dataCode) {bytes.push(b)}}const u16s = []for (let i = 0; i < bytes.length / 2; i++) {const n = i * 2u16s.push(((bytes[n] << 8) | bytes[n + 1]) + 40)  // EXTRA_LEN}return u16s
}

核心调用

核心调用代码如下：

    execute(this.data.ssid, this.data.bssid, this.data.password, this.data.localIp, false).then(res =>{if (res.acked){that.displaySuccess();console.log(res)}else{that.displayFail();console.log(res)}})

形参说明入下：

this.data.ssid要连接的AP的SSID也就是我们通常说的WiFi名称
this.data.bssid 要连接的AP的MAC地址，就是要连接的AP的网卡地址
this.data.password要连接AP的密码，也就是我们通常说的WiFi密码
this.data.localIp手机端Ip地址，后续配网成功后ESP32会回传手机ESP32的分配到的IP地址以及ESP32的网卡地址。由于ESP32回传采用的时UDP协议，无法保证可靠传输，所以建议在ESP32获得IP地址后，启动UDP广播，保证信息回传可靠。ESP32端Smartconfig代码如下：

体验小程序

通过点击小程序配网标签，进行smartconfig配网,为了提高配网成功率建议线上电ESP32，ESP32在无法上网后，会启动smartconfig等待配网，这是点击小程序配网，输入SSID和密码后，点击确定。

ESP32端成功配网的log如下：
