BT122

Bluetooth Classic Modules

BT122 is a dual-mode Bluetooth BR/EDR - BLE module targeted for applications that require both Bluetooth low energy (LE) and Classic connectivity. It can connect to legacy devices that only support Bluetooth SPP or Apple® iAP2 profiles as well to devices that support Bluetooth LE. BT122  integrates a high-performance Bluetooth radio, a low power ARM Cortex micro-controller and a Silicon Labs 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 BGScriptTM scripting language.
