SDK for building rApps and AI Agents in BubbleRAN MX-PDK and MX-AI

BubbleRAN O-RAN rApp SDK

The BubbleRAN rApp SDK is a Python-based software development kit designed to simplify the development, deployment, and integration of rApps (non-real-time applications) for the O-RAN RIC within the BubbleRAN architecture. This repository includes both the SDK framework (BubbleRAN Software License) and rApp (Apache 2.0 + Addendum).

Key Features

• 🛠️ Easy-to-use Python SDK for developing rApps and AI Agents
• 🔗 Integrates the LangGraph library with the A2A SDK for building AI Agents beyond POCs (ready for production)
• 📡 Supports O-RAN R1 interface in the K8s Custom Resource Definition (CRD) format
• ⚙️ Tools to communicate with BubbleRAN orchestration services
• ☁️ Cloud-native deployment with BubbleRAN MX-ORS, MX-PDK, and MX-AI products
