Product Details

BT121 Bluetooth Smart Ready Module

BT121 is a Bluetooth 4.1 Smart Ready compliant module that integrates a high performance Bluetooth radio, a low-power ARM Cortex microcontroller and a Bluegiga Bluetooth Smart Ready stack. This Smart Ready device provides simultaneous BR/EDR and BLE connectivity , communicating with both Bluetooth Classic and Low-Energy enabled devices.
The BT121 can be used with a separate host microcontroller, but user applications can also be embedded into the Flash microcontroller with the Bluegiga BGScript scripting language.
