Side-by-Side Comparison Bluetooth

Bluetooth 5 vs. Bluetooth Classic

Comparing 2 standards across 14 specifications. 14 key differences identified.

Comparing:
Bluetooth 5
Bluetooth Classic

Bluetooth 5 (encompassing v5.0 through v5.3) significantly expanded Bluetooth Low Energy with 2 Mbps high-speed (2M PHY), up to 4x range extension via forward error-corrected Long Range (Coded PHY), 8x advertising broadcast capacity (Advertising Extensions), and Isochronous Channels (v5.2).
