Bluetooth Logo - Official Symbol for Wireless Connectivity Technology #3895591 (License: Personal Use)

This black-and-white Bluetooth logo is a fusion of the ancient Norse runes ᚼ (Hagall) and ᛒ (Berkanan), representing the initials 'H' and 'B' of 10th-century Danish king Harald Blåtand (Bluetooth), who united warring tribes-mirroring the technology’s goal of unifying devices. Designed in 1998 by Swedish technician Jim Kardach, the symbol appears across billions of devices, from headphones to IoT sensors, signifying short-range wireless interoperability via the IEEE 802.15.1 standard.

Used on product packaging, device interfaces, marketing materials, and technical documentation to indicate Bluetooth capability; users search for this image when verifying compatibility, designing UIs, or researching wireless standards.
