[用户分享] 【TinkerNode NB-IoT】连接ONENET物联网,收集环境温度与湿度 |
本次采用HTTP协议数据封装接口形式连接到ONENET平台进行数据交互。 ONENET架构模型 主要代码如下: void sendOnenet(void) { char databuf[256]; memset(TXbuf, 0, sizeof(databuf)); PutOnenetBuf(databuf); Serial.println(databuf); client.print(databuf); } void PutOnenetBuf(char *buf) { char text[24]; char tempbuf[128]; memset(text, 0, sizeof(text)); memset(tempbuf, 0, sizeof(tempbuf)); strcpy(tempbuf, "{"); memset(text, 0, sizeof(text)); sprintf(text, "\"Temperature\":%0.2f,", dataInfo.tempreture); strcat(tempbuf, text); memset(text, 0, sizeof(text)); sprintf(text, "\"Humidity\":%0.2f", dataInfo.humidity); strcat(tempbuf, text); strcat(tempbuf, "}"); sprintf(buf, "POST /devices/%s/datapoints?type=3 HTTP/1.1\r\napi-key:%s\r\nHost:api.heclouds.com\r\n" "Content-Length:%d\r\n\r\n",DEVID, APIKEY, strlen(tempbuf)); strcat(buf, tempbuf); } 采用码盘的显示展示数据: 以上就是简单物联网数据采集的测试,下回见。 |
