TTN(The Things Network)

Preparation

Access the TTN website and create/log into a personal account , and select a cluster in the Console to start adding node devices and gateways.

Creating an Application

Go to applications -> Add application -> Fill in the Application ID and application name as desired, then click Create application to finish creating.

Creating a Device

Enter the created application page and click Add end device to start adding a node device. Choose Manually to custom create.

Device Information

Select the frequency band to be used according to the region where you are located and the device, and ensure that the frequency band used by the device you are using matches the sub-frequency band option used by the gateway. The LoRaWAN version and regional parameters need to be selected according to the protocol version supported by the actual hardware (for details, please refer to the corresponding product document page).

OTAA

For OTAA (Over-The-Air-Activation) connection mode, save the Device EUI, APP EUI, APP KEY parameters for later use in device connection. You can enter preset configurations or click Generate to automatically generate new keys. Click Register end device to complete creation.

ABP

For ABP (Activation By Personalization) connection mode, save the Device address, AppSKey, NwkSKey parameters for later use in device connection. You can enter preset configurations or click Generate to automatically generate new keys. Click Register end device to complete creation.

Programming the Device

In the previous steps, we successfully created a device in TTN. Next, we need to program the device to connect it to the gateway. Please enter the connection parameters obtained in the previous step in the example programs below for different platforms, depending on the connection method.

• For OTAA connection, you will need Device EUI, APP EUI, APP KEY.
• For ABP connection, you will need Device address, AppSKey, NwkSKey.

UIFlow

Below is an example using the UNIT LoRaWAN, fill in the connection parameters obtained in the previous steps into the configuration program, and ensure the frequency band, Class Mode, Rx2 frequency window, etc., match your actual settings. Then, run the program for testing.

Viewing TTN Logs

Live Data

After completing the program editing/running operation, if the device is successfully connected to the gateway, we can see the device's connection logs and the uplink data information in the TTN management page.

Messaging Data Transmission

Clicking Messaging allows manual data transmission to the device. Note: The latest data from the gateway is obtained only when the device uploads data.

MQTT Client

Obtain TTN server data through the MQTT Client for data retrieval/transmission. The MQTT SERVER URL, port, and login user information can be obtained on the TTN page.
