Hi, If you want help you should try to ask less general question 😬

Oh there is also some more specific question in the title, I tried to answer.

Leshan supports only COAP ?

Leshan aims to implement LWM2M specification.
Leshan v1.x (current stable version) implements LWM2M v1.0.x which specifies only LWM2M over coap(s)
Leshan v2.x (in development version) implements LWM2M v1.1.x which specifies only LWM2M over :

• coap(s) currently implemented.
• coap+tcp(s) for which there is some development started : Add CoAP over TCP transport layer  #1047
• coap over NIDD for which there is no development started.

Since Leshan v2.x a transport abstraction has been added to Leshan to be able to add new official (or to let user add their own) transport but this is pretty new and so probably improvable. See for more details : #1025 (comment)

LWM2M v1.2.x specifies LWM2M over :

• mqtt
• http but it seems not really functional : HTTP binding in LwM2M 1.2 seems to be broken OpenMobileAlliance/OMA_LwM2M_for_Developers#520

but currently there is no version of Leshan which aims to implement LWM2M v1.2.x.

Shall we use STOMP service supported devices with eclipse-leshan?

I'm not sure to understand the question.
Are you talking about STOMP ?
I don't know any LWM2M specification which define STOMP as transport. If this exits please share the link.

Should we close this issue ?

I close it but feel free to reopen if needed.

If you succeed to implement something using new Transport Layer Abstraction, please let us know. 🙏
