Page 3: Overview
SenseCAP LoRaWAN Gateway, please kindly refer to https://sensecap.seeed.cc. SenseCAP Sensor Nodes uses OTAA (Over The Air Activation), so theoretically three credentials (EUI, App EUI, App Key) are needed to configure and adapt the SenseCAP Sensor Nodes to your LoRaWAN network. -
Page 4: Retrieve Sensecap Credentials
【Technical Document】 2. Retrieve SenseCAP Credentials Device EUI is on the SenseCAP product label. Mark down the Device EUI and Device Code (as shown in the image above) for future uses. Use HTTP API to retrieve App EUI and App Key. You can use any HTTP tools or browser to issue an HTTP GET request. -

Page 21: Packet Parsing
5. Packet Parsing 1) Packet Initialization After being powered on or reboot, SenseCAP Sensor Nodes will be connected to the network using OTAA activation method. Each Sensor Node will send data packets to the server, including the following data: (1) Two all-zero payload packets, to drain pending downlink messages from the server. - Page 22 The rest frame types above 0x1001 are similar to 0x1001. They are measurement IDs， containing actual measure values of respective sensor. 0x1003 Light Intensity Please refer to the following documents for Measurement IDs: https://sensecap- 0x1004 22 / 38 © 2008-2019 Seeed Technology Co., Ltd.
