Silicon Labs BT121-A-V2 is a Bluetooth Smart Ready module targeted for applications that require both Bluetooth Smart and Classic connectivity. It can connect to legacy devices that only support Bluetooth SPP profiles as well to devices that support Bluetooth Smart.
BT121 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.
The BT121 combines has a high performance Bluetooth radio, a low power MCU and Bluetooth Smart Ready stack software. It’s easy to use and provides connectivity to Windows, Android and Apple devices and additionally allows customer applications to be programmed on the built-in MCU.
