RAK4200 Breakout Module Connecting to The Things Network (TTN) The Things Network is about enabling low power Devices to use long range Gateways to connect to an open-source, decentralized Network to exchange data with Applications. Learn more about the Things Network here. - Page 9 RAK4200 Breakout Module Figure 7 | Application parameters Here are the things that you should take note in adding an application: Application ID - this will be the unique id of your application in the Network. Please note that characters should be in lower case, no spaces are allowed.

Page 10: Registering A Device
Registering a device 3.2.2 Now we need to add our actual device (RAK4200). Refer to Figure 8 again and press the “register device” button that is marked with the red rectangle. Now you need to set some device parameters (Figure 9) - Page 11 Here are the things that you should take note in registering your device: Device ID - this is the unique identifier for your RAK4200 EVB within the particular application. You need to enter this manually. Device EUI - this is the unique identifier for your device in the network.
- Page 12 RAK4200 Breakout Module Figure 10 | Device Overview page Take note of the Activation Method which is set to OTAA by default (Figure 10). This is one of two options, ABP being the second one. We will provide instructions on both methods in the following sections, starting with OTAA.
- Page 13 RAK4200 Breakout Module Figure 11 | OTAA parameters set As these are randomly generated by TTN we need to update our RAK4200 with their values in order to be able to register it with the network. Note For the sake of this tutorial we will use an example that works withing the EU868 band in LoRa®...
