Java SDK

Java is a complete ecosystem that provides tools for developing software and deploying it in a cross-platform environment.

With the TTN Client you can receive activations and uplink messages from devices via The Things Network as well as respond with downlink messages.

⚠️ The support and maintenance for this SDK has been discontinued, it is not recommended to use the SDK for new projects.
