Answer
Canvas FW supports up to four connections for BL65x, BL54L15. BL54L10, BL54LM20A and BL54LM20B. However, one slot is always reserved for advertising and peripheral connection resulting in three concurrent Central connections.
Increasing connections reduces RAM available to the python App. Devices that contain a larger memory footprint could support a larger number but at this time all devices support four.
