Complete Local Name#

The cube's system software complete local name has changed from v02.0005 (BLE protocol version v2.3.0), to toio Core Cube-XXX. XXX is a unique cube ID string. Because this remains the same even after the cube is reset, it is useful for identifying individual cubes when dozens of cubes are being operated simultaneously. The ID string is not guaranteed to be a unique to every cube. It is also not the same number as the serial number printed on the cube.

The string used for the ID is a string of 3 alphanumeric characters consisting of a letter + number + letter in that order.

The letter can be uppercase or lowercase. The following letters are not used.
