Temperature and Humidity LoRaWAN Sensor2/122. Application Information2.1 FunctionThe sensor works in OTAA and Class A mode. DEVEUI, APPEUI and APPKEY are stored in the sensorand is necessary for joining a network. DEVEUI is labeled at the back of the device. APPEUI, APPKEYshould 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 ApplicationServer(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 registrationmessage for AS to validate.Sensor starts to work after receiving acceptance response or no AS reply after 5 times registrationtrial. Temperature and humidity will be reported to AS periodically. The duty cycle is configurable bycommands from AS. Temperature and humidity acquisition and report period is 10 minutes bydefault.According to LoRaWAN specification, downlink response time is decided by uplink duty cycle, usershould refer the needed response time to choose uplink duty cycle. Detailed downlink and uplinkdefinition are described below.2.2 Uplink Message2.2.1 RegisterBytes 1 1 1 1 2 2Item TYPE SMODE POWER CFG TH CRCTYPE fieldBit Name Value Description7~4 TYPE 0x1 Message type.
