Wakaama is not a library but files to be built with an application. Wakaama uses CMake >= 3. Look at examples/server/CMakeLists.txt for an example of how to include it. Several compilation switches are used:
- LWM2M_BIG_ENDIAN if your target platform uses big-endian format.
- LWM2M_LITTLE_ENDIAN if your target platform uses little-endian format.
- LWM2M_CLIENT_MODE to enable LWM2M Client interfaces.
- LWM2M_SERVER_MODE to enable LWM2M Server interfaces.
- LWM2M_BOOTSTRAP_SERVER_MODE to enable LWM2M Bootstrap Server interfaces.
- LWM2M_BOOTSTRAP to enable LWM2M Bootstrap support in a LWM2M Client.
- LWM2M_SUPPORT_JSON to enable JSON payload support (implicit when defining - LWM2M_SERVER_MODE)
- LWM2M_OLD_CONTENT_FORMAT_SUPPORT to support the deprecated content format values for TLV and JSON.
3.基础知识
通过URI访问LWM2M实体
/<object id>[/<object instance id>][/<resource id>]在LWM2M中，合法的URI应当像如下格式（注意，不能以/结尾）：
/<object id>[/<object instance id>][/<resource id>]
# legal example
/0
/0/0
/0/1
/0/1/1

7URI分别标识了访问资源的object id、object instance id、resource id，后两个id是可选的。
Depending on your platform, you need to define LWM2M_BIG_ENDIAN or LWM2M_LITTLE_ENDIAN. LWM2M_CLIENT_MODE and LWM2M_SERVER_MODE can be defined at the same time.
