Bluetooth® LE wireless connectivity technology is based on the IEEE 802.15 standard defined by the Bluetooth Special Interest Group (SIG), which is the organization that elaborates and updates Bluetooth specifications, manages qualification programs and protects trademarks. ST is a member of the global Bluetooth SIG community.

Bluetooth LE technology operates in the 2.4 to 2.485 GHz unlicensed ISM band and implements techniques including adaptive frequency hopping (AFH) to ensure other wireless technologies can run simultaneously on this portion of RF spectrum and that bandwidth can be shared. 

When designed for wireless battery-operated devices such as sensors for healthcare, sports, and fitness and for proximity and security applications, Bluetooth Low Energy, or Bluetooth Smart®, is based on the Bluetooth 4.x and 5.x specifications. 

ST offers state-of-the-art, easy-to-use Bluetooth Low Energy solutions with systems-on-chips (SoCs), baluns, matching filters and STM32 microcontrollers.
