My device include light and sensor together.

I enable sensor as below.

#define MD_SENSOR_SERVER_EN                        1        // MD_SERVER_EN
#define MD_SENSOR_CLIENT_EN                    1        // MD_CLIENT_EN

When I send below command in "sig_mesh_tool.exe",
e8 ff 00 00 00 00 02 01 ff ff 82 31
The light send debug message as below.
