- 关键代码展示
更改自己的IMEI、IMSI
const char endpoint_name[] = "666828270812034;1"; // IMEI;IMSI
温度资源
temp.type = NBIOT_FLOAT;
temp.flag = NBIOT_READABLE;
ret = nbiot_resource_add(dev,
3303, /* objId */
0, /* instId */
5700, /* resId */
&temp);
湿度资源
humi.type = NBIOT_FLOAT;
humi.flag = NBIOT_READABLE;
ret = nbiot_resource_add(dev,
3304,
0,
5700,
&humi);
4、OneNET平台查看温湿度数据

四、实训总结
总的来说这次实训很有收获，学到了由传感器采集的数据是如何上传到云平台的，也学会了平台的使用。唯一的不足是想吐槽实训设备，有不少已经不能正常使用了，每次拿设备都像是抽盲盒。
