BT121-A

Connectivity to Both Bluetooth BR/EDR and Smart Devices

BT121-A 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 or Apple iAP2 profiles as well to devices that support Bluetooth Smart. BT121-A integrates a high-performance Bluetooth radio, a low-power ARM® Cortex® microcontroller and a Bluegiga Bluetooth Smart Ready stack software marking it extremely easy-to-use as no RF or Bluetooth software development are needed. BT121-A 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 BGScript™ scripting language.
