3.Can self-defining data be used?
1.Does light application map support NB-IoT positioning? How to use it?
Answer: Yes. When the device is notified, the following two obj resources can be used for latitude and longitude report:
- object id is 6, resource id: 0 (latitude) 1 (longitude);
- object id is 3336, resource id: 5513 (latitude), 5514 (longitude)
It can be realized by choosing the data flow named “location” of the corresponding device in the map.
Note: Two resources shall be simultaneously reported and placed under the same instance.
2.Does the platform support DTLS encrypted transmission?
Answer: The current platform only supports PSK-based DTLS encryption (using Coaps and 5684 port connection); later, it will also support DTLS encryption mode based on public key and X.509 certificate.
3.Can self-defining data be used?
Answer: The platform data model complies with IPSO norm, and the developer can define the resource to be created. The data type of user-defined resource will be converted to Opaque type. The current page can display the resource value, but it can’t read, write and execute the user-defined resource; it needs to invoke corresponding Api interface.
