The hub2hub’s documentation!

The hub2hub library is not part of the original firmware of either the Robot Inventor hub or the SPIKE Prime hub. In the official SPIKE Prime firmware, a low-level ubluetooth library is available to be able to directly communicate over Bluetooth Low Energy (BLE). The documentation of this module can be found here: ubluetooth documentation

The main goal of the hub2hub library is to simplify the python code required to setup and maintain a BLE connection between LEGO hubs. Installation of the library and writing programs that use it are both possible via the official LEGO Education SPIKE Prime app, as explained here.

This library is still actively developed, at the moment two different versions are available that cannot be installed at the same time on a single hub.

• The latest version: 0.1.0 supports communication between a LEGO SPIKE Prime or LEGO MINDSTORMS Robot Inventor hub with a PoweredUP hub. This version is documented on this page.

• The previous version: 0.0.3/0.0.4 supports communication between LEGO SPIKE Prime and LEGO MINDSTORMS Robot Inventor hubs. This version is document here

In a future release functionalities of both versions will be combined.
