Side-by-Side Comparison Bluetooth

Bluetooth 5 vs. Bluetooth Low Energy

Comparing 2 standards across 13 specifications. 13 key differences identified.

Comparing:
Bluetooth 5
Bluetooth Low Energy

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).

Bluetooth Low Energy (BLE / Bluetooth Smart) was introduced in Bluetooth Core Specification v4.0 (2010) and enhanced through v4.2 (2014). Operating across 40 channels in the 2.4 GHz band, it replaced continuous connection streams with an event-driven Generic Attribute Profile (GATT) architecture, enabling devices to operate for years on a single coin cell battery.
