Application Information 2.1 Function The sensor works in OTAA and Class A mode. DEVEUI, APPEUI and APPKEY are stored in the sensor and is necessary for joining a network. DEVEUI is labeled at the back of the device. APPEUI, APPKEY should be provided by each application. Lansitec will help to configure this before shipping. After power on and join the Lora network, sensor will send registration message to Application Server(AS). If AS doesn’t reply, sensor will retry for 5 times before switching to default mode (periodically report mode). Configuration information of the sensor is included in this registration message for AS to validate. Sensor starts to work after receiving acceptance response or no AS reply after 5 times registration trial. Temperature and humidity will be reported to AS periodically. The duty cycle is configurable by commands from AS. Temperature and humidity acquisition and report period is 10 minutes by default. According to LoRaWAN specification, downlink response time is decided by uplink duty cycle, user should refer the needed response time to choose uplink duty cycle. Detailed downlink and uplink definition are described below. 2.2 Uplink Message 2.2.1 Register Bytes Item TYPE SMODE POWER CFG TH CRC Bit Name Value Description 7~4 TYPE 0x1 Message type.
