I. Introduction.
They remember who philosopher said: people want to grow up in frustration, will come to understand the road ahead more difficult in a time of failure, waiting for his was going to be how kind of difficulties, they should not want to be defeated, and that as long as beat them! ------- a file from Reed Middle School to see.
The current micro-channel small program but more and more fire! And now, in a micro-channel program development small applications that can be cross-platform, can be described as significant savings in development cycle, recently a lot of people have asked this thing in the group, I slowly for everyone to elaborate this process is how !
In the previous article point I link , I mentioned a need to do a server H5interface implemented in a micro-channel public number and loaded in the esp8266distribution network principles. In the esp8266end is rtos2.0or is nonos 2.0 、3.0realized, however, until today 2019-4-10demonstrates so far, the official website is still out near-field discovery. While supporting airkissthe distribution network, but this is far less than our development needs.
Angrily, I have access to micro-channel hardware development documentation, and familiarity with the development of esp8266, three hours to get out, to pit the migration process, as well as distribution network compatible iosand Androidend!
Second, prepare materials.
- With a number of public function interface device turned on! General business or an individual certified test number! Open with optional device features!
- A server can be connected to external networks, Ali cloud purchase or other platform!
- A domain name record success, and have SSL certificate!
- A esp8266 minimum system module!
How to micro-letter code development process ends, Bowen omitted! The back will be a more detailed tutorial for everyone, and this article focuses on the principles of micro-channel and near-field discovered how to send a message to the public micro-channel number, to achieve binding!
Third, the binding principle.
As already said: Lexin of esp8266 rtos3.1 sdkthe code (below unified version of the sdk for this purpose) distribution network model has to support airkissit! But until today 2019-4-10so far, no code is found near field; I went to the micro-channel hardware cloud document looked at, it is also quite simple transplant!
下图为微信硬件云提供，可以看到其原理非常简单，是一个本地的UDP通讯的过程；由设备端esp8266往局域网内的所有设备指定的端口12476发送一个特定的报文，微信客户端就会近场发现收到此信息！
- 假设当微信客户端收到此设备发来的信息之后，处理给服务器，就可以实现绑定当前配网用户保存在服务器记录里面了！
四、代码实现。
- 一、首先要开启
udp客户端，因为这个版本是用的是lwip，所以创建socket！ - 二、然后向
255.255.255.255这个服务器的12476端口发送指定的内容，此内容要经过微信提供的库文件的某个函数再一次处理得到！ 并非直接传自己的内容过去！ - 三、最后开始发送，微信提醒最好是 每隔5s内发送一次，发送20次以上，提高设备被微信客户端发现的速度：
4.1 添加airkiss静态库到工程！（非常重要）
- 请到微信硬件云官方找到
ESP8266的下载: https://iot.weixin.qq.com/wiki/new/index.html?page=4-1-4 - 集成后的结构如下，集成进去这个版本的过程这个坑我已经深深踩过了：
4.2 创建socket！
int sock_fd;
struct sockaddr_in client_addr;
sock_fd = socket(AF_INET, SOCK_DGRAM, 0);
if (sock_fd == -1)
{
printf("[xuhong] failed to create sock_fd!\n");
vTaskDelete(NULL);
}
memset(&client_addr, 0, sizeof(client_addr));
client_addr.sin_family = AF_INET;
client_addr.sin_addr.s_addr = inet_addr("255.255.255.255");
client_addr.sin_port = htons(LOCAL_UDP_PORT); //宏定义 12476
4.3 开始广播！
int err;
int count = 0;
while (1)
{
lan_buf_len = sizeof(lan_buf);
//把数据给微信接口二次加密处理返回
airkiss_lan_ret_t ret = airkiss_lan_pack(AIRKISS_LAN_SSDP_NOTIFY_CMD, ACCOUNT_ID, buffer, 0, 0, lan_buf, &lan_buf_len, &akconf);
if (ret != AIRKISS_LAN_PAKE_READY)
{
printf("Pack lan packet error! \n");
vTaskDelete(NULL);
}
err = sendto(sock_fd, (char *)lan_buf, lan_buf_len, 0, (struct sockaddr *)&client_addr, sizeof(client_addr));
ESP_LOGI(TAG, "[SY] send local ! %d ", count); //打印广播的次数
if (err < 0)
{
printf("[SY] failed to send local ! ... \n");
}
else
{
count++;
if (count > COUNTS_BOACAST)
{
//关闭通道
handleCreatSocket = NULL;
shutdown(sock_fd, 0);
close(sock_fd);
vTaskDelete(NULL);
}
}
vTaskDelay(1500 / portTICK_RATE_MS); //延迟1.5秒
}
五、特别强调睬坑。
- 前端笔记：
onScanWXDeviceResult方法在苹果手机包括iPhone X、iPhone6收不到wifi设备的传来的一些信息！本人经过多次查阅，需要在openWXDeviceLib方法调用时候，也就是初始化硬件设备库，传入加上这个公众号原始ID。具体如下：
//初始化硬件设备库，否则部分机型无法初始化成功导致后面的扫描不了本地设备！
wx.invoke('openWXDeviceLib', {'connType': 'lan', 'brandUserName': 'gh_xxxxxx'}, function (res) {
alert("openWXDeviceLib：" + JSON.stringify(res));
});
- ①: [device] end notice pit micro-channel public number distribution network airkiss development process, device-side
deviceIDpass over format can not be ajsonformat, a personal recommendation to this stringbase64passed to the micro-letter encrypted. Otherwise, Apple did not directly no callback error message! ! ! - ②: [pit] If the front end initialization js pay attention
js sdkwhen there is no mass public number id, only for Apple phone such as iPhone X local LAN scanning device is not a callback, and no error message! - ③: [device] end pit notice last point: the device side of the pass in the public micro-channel number must be for the public micro-channel number of the original ID, format:
gh_xxxx! Otherwise, Apple phone is not the callback information! But this has nothing to do with Android phones! Pass parameters is to call special attention to the following function:
airkiss_lan_pack(airkiss_lan_cmdid_t ak_lan_cmdid, void* appid, void* deviceid, void* _datain, unsigned short inlength, void* _dataout, unsigned short* outlength, const airkiss_config_t* config);
- Functions for packaging,
ak_lan_cmdidthe type to be packaged,appidfor the number of public vendor ID,deviceidas the device ID,_datainas data to be transmitted,inlengththe length of transmission data_dataoutis packetized data buffer,outlengththe buffer space is, the function returns successfully the assignment of the actual length of the packet!
- Here is the code I have this display hardware Bowen in effect micro-channel public number:
Sixth, download.
- Thank you for viewing my blog, to support it give enough attention! Thank you!
- Code has been uploaded to my warehouse, I will update this library, welcome star! https://github.com/xuhongv/xLibEsp8266Rtos3.1AirKiss
