There was a Danish king, Harold, who worked hard to unify in the 10th century
The king liked blueberries so much that he always enjoyed them.
He ate so much that his teeth were blue.
So the king's nickname was Bluetooth.
It is said to have been nicknamed the king as a system that integrates multiple devices as if it were a unit of Nordic countries.
