I’m searching for information to see if HL7800 module supports LwM2M. I can see that there are commands for connecting to AirVantage that also use LwM2M, but it looks very specific to that service provider. Is it supported or planned to have capability to connect to any generic LwM2M server? ---

I don’t see any AT command supporting this. ---

HL7800 supports LWM2M but cannot connect to any generic LWM2M server. I don’t heard any plan to support other LWM2M severs. ---

Hi, Please can you let me know if the LWM2M server support status for the HL7800 modules is still as above, with integration with other LWM2M servers not being supported? Or has this changed now? Thanks. ---

@graham.hunter No it is not supported in the current firmware and is unlikely to be in future releases, this has been significant topic of conversation. Unfortunately not all LWM2M servers are created equal. This the conclusion we have come to after working with several of them (as the operators require us to interface to theirs for device management) as it is very difficult to come up with a generically compatible stack that will work with any LWM2M server where you have limited ability to configure it (through generic AT commands). It really requires lower level firmware access to tweak it to resolve issues that you might encounter. If a given customer hits a problem with it not working with their server it would be a never ending support story for us to modify the stack. We will shiortly be supporting various modes and features for security and easy UDP data transmission meaning you can go up to these levels and then an application would need to host a LWM2M stack which could then have the modifications performed as required.

Hi, since 2020 has anything changed in this subject ? The latest manual has 21 pages on LWM2M. SI there any paper on how to connect to a LWM2M server using these commands ? Thanks. ---

@pratos So there are several carriers who require us, as part of their certifications, to work with their LWM2M servers as stated in the intro to the LWM2M chapter. We have worked with them to achieve the approvals and so we now it works. The position re LWM2M for generic application use remains the same, which is that not all servers are equal and we would be in a perpetual maintenance cycle to correct for every nuance in different implementations as they came up. Typically if you need to send data to one of the cloud services they themselves recommend MQTT(S) which we support. Regards Matt ---

Thanks for the prompt response. Yes we do have cloud systems working with many thousand of devices in the filed using MQTT. LWM2M exists as a server in major Smart city platforms and this is what we want to do to connect taking in to advantacge the capabilities of LWM2M mainly for provisioning and mass deployement. Also FOTA not for the modem but of our MCUs. Providers like AT&T, Verizon and the likes want to have the devices connected on them to sell SIMs and what they offer is basic comms for smart meters connectivity, etc. I was hoping for a paper at least showing how to connetc to such a server to understand the depth of their implementation and if it make any sense to try it. Nevertheless no provider in Europe has such LWm2m running.
