ChirpStack: The New Open Source LoRa Server

Over the past couple of years, CableLabs and Orne Brocaar have introduced multiple major releases of the LoRa® Server, a community led open source LoRaWAN® network server. The goal of this effort is to provide a powerful tool for enabling LPWAN services using unlicensed bands worldwide. The server is licensed under the MIT license, so it can be used freely for any use from testing to production. Our objective continues to focus on enabling growth and creativity in the LPWAN ecosystem using the LoRaWAN protocol.

We are excited to announce that LoRa Server has been renamed ChirpStack™. What does this rebranding mean for our community of users? Well, nothing really, with exception of assuming a new name. The server continues to provide the functions, capability, LoRa Alliance® compliance and MIT licensing it always has. However, the name and URL location of the resources has changed.

The ChirpStack software, source-code and documentation are now available here: https://www.chirpstack.io. The discussion forum is now available here: https://forum.chirpstack.io

LoRa Server renamed ChirpStack

Since its debut in 2016, the LoRa Server project has gained a lot of traction and is now being used by thousands of users from (currently) 144 countries around the world. And, we fully expect the ChirpStack project will continue to serve this user base with valuable tools, software, and discussion.

“Solutions built on Semtech’s LoRa devices offer the real potential to change the world by delivering analytical insight into how we live and work today. To create a smarter tomorrow, developers working with LoRa devices and the LoRaWAN protocol need access to easy-to-use accelerators that help drive applications to market more quickly,” said Alistair Fulton, Vice President and General Manager of Semtech’s Wireless and Sensing Products Group. “CableLabs and its ChirpStack software have contributed to the growth of LoRaWAN, creating value to the ecosystem by helping to simplify the IoT development process and enable the creation of new, innovative products for the next generation of use cases.”

We have automated the renaming process in the lastest version as much as possible, and we hope this migration will only be a nominal inconvenience. A full list of considerations and changes have been provided on the forum. If you experience any challenges with this migration, please communicate issues and feedback on the forum.

In the latest release(s) you will find a lot of interesting new features. Using NetID filters it is possible to reduce the bandwidth usage of your gateways. This is useful when you are using a cellular backhaul. We have also made it easier to correlate log messages across the different components, which will help when troubleshooting issues as they occur. To increase the geolocation accuracy, we have added support to perform geolocation on multiple uplink frames. We will continue to improve and add new features and we are looking forward to your feedback and contributions to the ChirpStack project.
