| The `deviceShifu-lwM2M` will represent each lwM2M object as an instruction that can be accessed through a RESTful API. The API will use the POST method for write operations and the GET method for read operations. The supported data formats for lwM2M v1.0 are TLV, JSON, Plain text, and Opaque. | ||

| deviceShifu-lwM2M's lwM2M server will handle Register, Update, De-register, Read, Write, Observe and Notify. |

you mean external LwM2M server? Like mosquitto broker for MQTT. Not part of deviceShifu

No it is a part of deviceShifu, for devices are LwM2M client and deviceShifu is server which device can connect to us
| - normal mode: just like the other deviceshifu, when call the instruction, deviceShifu will send Read or Write Request to deviceShifu and return response | ||
| - observe mode: this mode will set the min and max notify time, then device will notify data when data changed or timeout. deviceShifu will record data, and return the data store in the memory cache when call the instruction. and this kind of mode also support read and write operation. | ||
