Figure 42: OTAA Test Sample Data Sent Viewed in The Things Stack

Connecting with ChirpStack

This section shows how to connect the RAK4600 to the ChirpStack platform. As described in the ChirpStack
website:

“The ChirpStack open-source LoRaWAN Network Server stack provides open-source components for LoRaWAN
networks. Together they form a ready-to-use solution including a user-friendly web interface for device
management and APIs for integration. The modular architecture makes it possible to integrate within existing
infrastructures. All components are licensed under the MIT license and can be used for commercial purposes.”

Figure 43: RAK4600 in the context of the ChirpStack platform

The architecture of the ChirpStack platform is shown in Figure 43. Similar to the case of TTN, the RAK4600 is
located in the periphery and will transmit the data to the backend servers through a LoRa gateway. More
information about this architecture can be found at
