Bluetooth BT121 Development Kit Design Document

BT121 is a Bluetooth dual-mode module suitable for applications requiring Bluetooth LE and BR/EDR connections. It can connect to older devices that only support Bluetooth SPP or Apple® iAP2 profiles as well as devices that support Bluetooth LE. The BT121 integrates a high-performance Bluetooth radio, a low-power ARM Cortex microcontroller and Bluegiga Bluetooth dual-mode stack software, requiring no RF or Bluetooth software development, making it very easy to use. The BT121 can be used as a modem with a separate host MCU, but applications can also be embedded into the built-in ARM® Cortex® MCU with the Bluegiga BGScriptTM scripting language.
