2. A node application (OTAA/ABP) corresponding to the gateway frequency band range has been created on TTN.

3. The ThinkNode-M6 has been connected to the LoRa Antenna and GPS Antenna.

1.7 *Configure Programming Environment*

1. Download the sample project file: Obtain the LoRaWAN network access test code folder;

*Sample File Project Link:*https://github.com/Elecrow-RD/ThinkNode-M6-Outdoor-Solar-Power-for-LoRa/tree/master/demo_code

Open the downloaded project: LoRaWAN_Test_868_SX1262

1. Open the Arduino IDE, load the .ino file in the project, and open the config.h configuration file; modify AppEUI, DevEUI, AppKey and the regional frequency band in the config.h configuration file (replace them with the device information registered on the TTN platform).*（replace them with the device information registered on the TTN platform）*（备注：红色字体加粗）

*The config.h file is the configuration header file for the LoRaWAN terminal, with core functions including:*

Defining the pins of the SX1262 RF module, LoRaWAN network access parameters (JoinEUI/DevEUI/AppKey/NwkKey), regional frequency band (US915 or other regional frequency bands) and uplink transmission interval (5 minutes), encapsulating the LoRaWAN node object, and providing auxiliary functions such as status code parsing, error debugging, and byte array printing. It provides basic configuration and tool support for LoRaWAN terminal network access and data transmission.

*Note: The node information (AppEUI, DevEUI, AppKey) and region must correspond to the configuration file settings.*

1. Board Selection:「Tools」→「Board」→「Adafruit nRF52」→「Nordic nRF52840 DK」.

1. After connecting the Type-C USB Data Cable to the host computer, select the serial port number you are using; the port COM24 is selected here.

1.8 Code Upload and Verification

1. Click Upload to upload the code.

1. After successful operation, open the Serial Monitor (Baud Rate: 115200).

1. Serial Output Information Analysis:

*Note: If no information is output on the serial port, close the Serial Monitor, click the RESET button on the ThinkNode-M6, and reopen the serial port to view the printed information.*

Complete status feedback after the LoRaWAN terminal device accesses the TTN network and sends the first uplink data:

• The terminal has successfully accessed the TTN network (DevAddr assigned normally).

• The first uplink data (01020304) has been sent, and TTN has replied with MAC commands via the Rx1 window (no service downlink).

• The wireless link quality is excellent (RSSI/SNR values are ideal), and the transmission parameters comply with the US915 frequency band specifications.

• It is necessary to wait about 20 minutes before the terminal initiates the next uplink (subject to TTN Fair Use Policy/Duty Cycle Restrictions).

• TTN Platform Verification: Log in to the TTN application details page and click Live Data; you can view the payload data 01020304 uploaded by the node, indicating that the data has been successfully uploaded.

*Core Logic:*

The ThinkNode-M6 terminal device completes LoRaWAN network access detection and connects to the TTN network via OTAA mode. After configuring the RF module and network parameters, it periodically sends a fixed byte array {0x1,0x2,0x3,0x4} as the uplink payload to the TTN network (the second uplink frame is acknowledged and requests link/time MAC commands). It receives and parses downlink data and prints link status information. Finally, the data 01020304 can be viewed in the Live Data of the ThinkNode-M6 node on TTN.

1.6 ThinkNode-M6 Terminal Node Configuration Parsing Script

1. Click the ThinkNode-M6 node name and select Payload Formatters.

1. Select Custom Javascript Formatter.

1. Open the TTN Data Parsing Script file in the project folder.

JS Parsing Script Function:

After receiving the byte array and port parameters, it parses the illuminance (uint16 type) from bytes 0–1, humidity (uint16 type, actual value obtained by dividing the original value by 10.0) from bytes 2–3, and temperature (uint16 type, actual value obtained by dividing the original value by 10.0) from bytes 4–5 in little-endian order. Finally, it returns a JSON object containing illuminance, humidity (% RH) and temperature (°C), with customizable field names to adapt to TTN integration.

function Decoder(bytes, port) {
  // Decode illuminance (bytes 0-1, little-endian, uint16)
  var lux = (bytes[1] << 8) | bytes[0];

  // Decode humidity (bytes 2-3, little-endian, uint16, actual value = raw value / 10.0)
  var humidityRaw = (bytes[3] << 8) | bytes[2];
  var humidity = humidityRaw / 10.0;

  // Decode temperature (bytes 4-5, little-endian, uint16, actual value = raw value / 10.0)
  var temperatureRaw = (bytes[5] << 8) | bytes[4];
  var temperature = temperatureRaw / 10.0;

  // Return JSON object, field names can be customized, related to subsequent TTN integration
  return {
    lux: lux,
    humidity: humidity,        // Unit: %RH
    temperature: temperature   // Unit: °C
  };
}

1. Copy the JS parsing script to the *Formatter Code* edit box to realize the parsing of temperature, humidity and illuminance from the 6-byte payload.

1. Click *Save Changes*.

1. Verify the parsing effect: After waiting for the ThinkNode-M6 to send uplink data, enter the terminal device *Live Data* page to view the parsed visualized data:

The data fields are displayed correspondingly: illuminance (lux), humidity (% RH) and temperature (°C), completing the visualized parsing of multi-sensor data.

*Core Logic:* The ThinkNode-M6 terminal device collects illuminance data from the BH1750 sensor and temperature & humidity data received via the software serial port. It formats the data into a 6-byte uplink payload, accesses the TTN network via LoRaWAN OTAA mode and sends the payload periodically. Meanwhile, it receives and parses downlink data and prints link status information. Finally, the illuminance, temperature and humidity data can be viewed in the *Live Data* of the ThinkNode-M6 node on TTN.
