The purpose of this tutorial is to build a system that uses LoRaWAN to send sensors data from an IoT device without an Internet connection.We will build a RIOT-OS application that will be executed on the B-L072Z-LRWAN1 LoRa kit over IoT-LAB.We will use TheThingsNetwork to interconnect the sensor devices with the cloud infrastructure via the MQTT protocol.AWS IoT Core for LoRaWAN decrypts the binary message and encodes the decrypted binary message payload as a base64 string. The resulting base64-encoded message is sent as a binary message payload (a message payload that is not formatted as a JSON document) to the AWS IoT rule described in the destination assigned to the device.LoRa Alliance, LoRaWAN™ 1.1 Specification Kim J., J. Song, A Dual Key-Based Activation Scheme for Secure LoRaWAN. Wireless Communications and Mobile Computing Volume 2017, Article ID 6590713 ...Tucker budzyn siblingsDecoder is a Javascript function that The Things Network has already set up for us. It takes two arguments called bytes, an array containing our payload, and port, the LoRaWAN™ "FPort" of the packet. FPort identifies the end application or service that the packet is intended for. Port 0 is reserved for MAC messages.The LoRaWAN Driver was ported to BL602 from Apache Mynewt OS. (This implementation of the LoRaWAN Driver seems outdated. There is a newer reference implementation by Semtech. See this) 3.2 Join Network Request. Before transmitting a LoRaWAN Data Packet, our BL602 gadget needs to join the LoRaWAN Network.LoRaWAN units need no change on the watchdog side as their communication with the Network Server remains unaffected and the un-encrypted payload will now be available there. Data payload structure. To further decode the payload and extract the meaningful parameters, the structure of the payloads needs to be known.

  • Decode the payload in WarpScript. Now, it is time to write the WarpScript to decode the payload in Warp 10. Here the raw payload decoded by Warp 10: A1FC30006B47D201DD02. Temperature is 733, 0x2DD. The end of my payload is DD02. I have an endianness problem! Note for next Warp 10 release: add functions to easily reverse bytes arrays.
  • Send the same byte in your uplink message to let the payload decoder know how to decode the message. e.g. if The pressure sensor is disabled, only 3 * 4 = 12 bytes are sent for the sensor values and the bytes of the 3rd sensor in the byte stream belong now to the illuminance sensor rather than the pressure sensor.
  • The first ID is given by the LoRaWAN Port. The ID determines the length and datatype of the value bytes. Using the example above: FPort = 41: this gives us the first ID (I2C temperature probe 1 (red)). This implies the value is INT16 (2 bytes) x 100 degC. 0x 5f05 = the 1st 4 bytes of payload. INT16 x 100 degC.
