The BT121 is a Bluetooth Smart Ready module targeted for applications that require both Smart and Classic Bluetooth connectivity. It can connect to legacy devices that only support Bluetooth SPP or Apple iAP2 profiles as well to devices that support Bluetooth Smart. The module integrates a high performance Bluetooth radio, a low-power ARM Cortex micro-controller and a Bluegiga Bluetooth Smart Ready stack software marking it extremely easy-to-use as no RF or Bluetooth software development is needed. BT121 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 Bluegiga BGScriptTM scripting language.
