Re: [leshan-dev] Continuous data with Lwm2m

[Joakim Hellberg <joakim.hellberg@xxxxxxxx>]

It is not in scope of lwm2m specification, but by implementing and registering a smart object defining what endpoint to send telemetrics to and credentials + x options you could tell your device where to send data and how. I don’t think such an object exists today, but I have been discussing this topic with one of the co-authors of the IPSO specification, Jaime Jimenez. (https://github.com/IPSO-Alliance/pub/tree/master/docs).

 

You register such objects at oma: http://www.openmobilealliance.org/wp/OMNA/LwM2M/LwM2MRegistry.html

I am not an expert but it sounds like MQTT or CoAP would be better suited for your use case.

Hi folks,

sorry if this is not the right mailing list for this, maybe you can point me at a better place to discuss this?

 

I am currently evaluating Leshan for use in our upcoming projects, but I am not sure how to achieve this with Lwm2m:

 

* Our devices do continuous measurement of sensor values
* All values have to be transmitted to the server
* Data should be transmitted in chunks to keep network traffic down
* All data chunks should be stored on device until receipt is acknowledged by server. 

 

Can this be achieved with Lwm2m? Or would maybe a different protocol be a better fit here? 

 

Thanks for your help!
