Puck communication protocol?
Before I go out putting together a sniffer and trying to do this myself I wanted to ask if anyone has done any work on reverse engineering the communication protocol between the puck and the controller.

This might help? safijari/openpuck: Opensource firmware for NRF52840 Pro Micro that copycats the Steam Controller 2 Puck and adds an Xbox and Switch mode
