I’m holding off on the bootstrap changes until some of the existing pull requests can be merged. In particular
#430,
#431, and #435.

Subject: Re: [wakaama-dev] LWM2M 1.1 next steps
David,
- Yes, LWM2M_SUPPORT_TLV. Also always defined when LWM2M_BOOTSTRAP_SERVER_MODE is defined. Only off by default for LWM2M 1.1 clients. I actually have this ready to go, it took only about
an hour. It might have merge conflicts with the SenML JSON support so I was waiting to create the pull request.
- Actually I think it is mostly client side. The resource instance ID need to be passed to the object read or write function. I think there are TODOs in the code most places that need
to change. On the server side I think it would “just work”, but obviously I haven’t tested it yet.
- Adding the preferred content format to the Bootstrap-Request. Adding the Bootstrap-Read. There are changes to the BootStrap-Discover, but I need to review the details. The server initiated
bootstrap is completely different for LWM2M 1.1. Server object resources 9 (Bootstrap-Request Trigger) and 12 (Last Bootstrapped) would probably be part of this, although Last Bootstrapped may not be possible unless the origin for lwm2m_gettime() is Jan 1
1970. I’ll probably break this up into several pull requests to keep it from being too much at once.

Scott
Hi Scott,
- Remember that TLV is still mandatory to support for the Server. I guess you consider a compilation flag. Like for LWM2M_SUPPORT_JSON, it should be always defined when LWM2M_SERVER_MODE
is defined.
- I guess you are talking of the Server-side APIs. For the Client-side it should “just work” with the new URIs and the data encoding.
- Could you elaborate ? From the top of my mind, there are the Bootstrap-Read operation, the new Bootstrap-Discover parameters, and some new resources in the Server Object.
Regards,
David Navarro
The next few things I plan on working on are:
- Making TLV support optional.
- Expanding read/write/observe to handle resource instances.
- Bootstrap changes.
Regards,
Scott
