Bluetooth BR/EDR Modules

Silicon Labs’ dual-mode Bluetooth basic rate/enhanced data rate (BR/EDR) - BLE modules target applications that require both Bluetooth Low Energy (LE) and Classic connectivity. These modules can connect to legacy devices that only support Bluetooth SPP or Apple® iAP3 profiles as well to devices that support Bluetooth LE. Silicon Labs BR/EDR modules integrate a high-performance Bluetooth radio, low-power ARM Cortex microcontroller and BGScript™ stack software.

BT122 can be used as a modem together with a separate host MCU, but applications can also be embedded into the built-in ARM® Cortex® MCU with the Silicon Labs BGScript scripting language.
