The name Bluetooth is one that demands inquiry, but only few out of its millions of users make that attempt. Although named after a blueberry-loving Danish King, Harald Blatand, it was invented by Ericsson in 1994 (a time when wires ruled) with the primary objective of providing a wireless solution to headphones. It quickly became evident that it was capable of so much more. The rest, they say, is history. To function, a Bluetooth chip is required on both devices (the receiver and sender), to send small packets of data over a short radio wave. Since its invention, Bluetooth has retained its status as a primary wireless solution. This is mostly due to its affordability and its ability to maintain a stable wireless connection with low battery consumption. With IoT rapidly growing, Bluetooth has made considerable effort to meet the needs of multiple devices by releasing a new update allowing the connection of up to 7 devices at once. It’s safe to say that Bluetooth will be here for a long time.
