Ⅰ、 Development Environment Preparation

Ⅱ、Hardware Connection

2.1Power supply method

After the device is powered on, it will automatically send incoming and report data, with a default interval of 2 minutes after successful incoming.

2.2 Serial debugging

       Serial port location 

         Serial module connection method

Find the serial port connection location and connect the computer to the collector through the serial port module with a Dupont cable, after a successful connection. Open the development material of the collector setup assistant V1.10. Baud rate default: 115200, serial port number will be recognized automatically.

After opening, the following configurations can be set through the software.

AI-related configuration: (Unit: mV)

Maximum setting range of voltage: -5V~+5V

Hibernation-related configuration: Set the device hibernation time.

Function switches: Switches for debugging and controlling each function module.

Modbus configuration: standard Modbus protocol.

2.3 Jlink Download Debug

Hardware connection schematic

After connecting to Jlink, you can update the firmware and view the logs during debugging through Jlink. 

Ⅲ、Platform Account Registration

The helium Console account registration address is as follows：

https://console.helium.com/

Ⅳ、Terminal Registration

After logging into the Helium console platform, click Device --> Add a new device to enter the Add Device interface.

Enter the triad information of LoRa Tracker PCBA (Deveui, Appear, APPkey) and click "Save Device".

(Note: the three groups of information to obtain the way: 1. From the manufacturer 2. scan the label QR code)

After adding, wait for the data to be received.

Ⅴ、Terminal Data View

Check the LoRa Tracker PCBA data on Helium Console. Click Device->Device name, view Device detail, and check the status data reported by LoRa Data Collector.

Ⅵ、Add custom scripts

Parses the reported raw data through a custom script. (See attachment/consult the manufacturer for examples of parsing scripts by message protocol.)

Copy and paste the custom parsing script into the location below.

Ⅶ、Add Application Integration

Configure the application platform to be forwarded (HTTP/MQTT)

If you choose MQTT, you need to add your personal server address in location 1. Location 2: Add the uplink band.

Ⅷ、Add flow chart

After adding device/product tags, scripts, and platform addresses, different devices/tags are connected to the corresponding platforms through specific parsing scripts.

Make the streamline connection. As shown below:
