Hi,
I heard by ARM's EC rep who seems to participate in the WG for this at OMA
about Lightweight M2M and did a review of the current "Candidate Spec"
(see http://technical.openmobilealliance.org/Technical/current_releases.aspx
despite its "1.0" number it is no more than an Eclipse project "incubating"
or a non-final JSR in the Java Community Process;-)
Unfortunately there are still many things either undefined, vaguely defined
or insufficient, just taking a fuzzy "time interval in seconds" as an
example, where Real Time M2M expecially if you have a C system use millis or
even nanosecond precision. That and other things not yet formulated make OMA
Lightweight M2M immature and a project should not rely on something still
incomplete.
There are overlaps, especially with the Californium project, though most of
them use Java or JavaScript.
I'd wait wit this till the standard is mature and accepted, rather than a
Candidate Spec.

Despite its name, liblwm2m is not a library but files to be built with an
application. It is written in C and designed to be portable on POSIX
compliant systems.
Two compilation switches are used: LWM2M_CLIENT_MODE and LWM2M_SERVER_MODE.
Defining LWM2M_CLIENT_MODE enables the LWM2M Client interfaces. Defining
LWM2M_SERVER_MODE enables the LWM2M Server interfaces. Both can be defined
at the same time.
