Step 1: Configuration with The Things Network (TTN)

Set up your account with The Things Network

To set up your account with The Things Network, follow these steps:

Go to https://www.thethingsnetwork.org/
Create an account or log in to your existing account

After Login; Click Console.

From the console screen, click Gateways.

Click register gateway

Obtain the gateway ID from the Clodpi Gateway Login.

Step 2:

Power On the Gateway and check for Power LED to Glow
Power On the Gateway will initiate the Wi-fi connection of the Gateway for configuration purposes.
Identify the Open Wifi connection – Start or end with AP
Connect to this Wifi connection , in this case it is AP-F3830
Once connected , open any browser and connect the Gateway configuration panel by accessing the IP address : 192.168.55.1

Figure : Access Gateway with standard wifi access

Note: This wifi access is unsecured (with out password), so it is recommended to change or secure the wifi access using wifi encryption.

Step 3:

Figure : Login to Gateway

Now go to Packet Forward ; Setting , get the Gateway ID shown in below figure

Step 4:

Fill in the information to register the gateway as shown below.

Note :If the gateway is set to use “The Things Network Legacy” preset, be sure to check I’m using the legacy packet forwarder. Otherwise, the gateway can use the preset and the checkbox should be left unchecked

Enter Gateway EUI , add 0000 prefix in Gateway Id to make it 8byte address
In case of ClodPi Indoor Gateway, we need to check the "I'm using the legacy packet forwarder"
Enter Description as you like
Select Frequency Plan as applicable to your region. In case of India it is "India 865-867 Mhz"

Figure: TTN Gateway Registration

System will automatically Select Router "ttn-router-asia-se"

Select location on Map , Antenna Placement - Indoor or Outdoor and Register Gateway

Figure: Mark Gateway Location

Configure Server Address: router.as2.thethings.network
Server Uplink Port: 1700
Server Downlink Port: 1700

Note : You should point your gateway to one of the following addresses instead:

router.au.thethings.network (Australia, 915 MHz)
router.as1.thethings.network (Southeast Asia, 920-923 MHz - 'AS923' low)
router.as2.thethings.network (Southeast Asia, 923-925 MHz - 'AS923' high)
router.eu.thethings.network (Europe, 868 MHz)
router.us.thethings.network (America, 902-928 MHz)
router.kr.thethings.network (Korea, 920-923 MHz)

If you need more help with gateway setup, please see the TTN documentation here. Some gateways require special tweaks to their configuration files. If you are having difficulty with the setup, try searching the forums here for a solution.

Once your gateway is set up and turned on, you should be able to see any LoRaWAN traffic it sends or receives in the Data page for your gateway. It will however remain encrypted on this page.
