The BT SDK contains everything you need to build applications for the following dual mode (BR + EDR + BLE) Bluetooth 5.0 core spec compliant solutions: CYW20706, CYW20719B2, CYW20721B2, CYW20735B1, CYW20819, CYW20820, and CYW89820. The SDK, along with the ModusToolbox IDE and configurator tools, form a powerful but easy to use toolset that helps you create amazing Bluetooth-enabled IoT solutions like beacons, trackers, smart watches, audio devices (headsets, speakers), hid devices (remotes, mice, keyboard), medical devices, and home automation platforms.

ST is launching today the BlueNRG-LP, the first Bluetooth Low Energy SoC to support 128 concurrent connections. It is also our first device to receive the Bluetooth Low Energy 5.2 certification. The BlueNRG-LP supports features such as Long Range, 2 Mbps transfers, and advertisement extensions, to name a few. Additionally, it draws from previous architectures to offer the broadest dynamic range ever on an ST Bluetooth chip. To achieve such a level of performance and optimization, our teams focused on the SoC’s radio and the microcontroller. The latter is now a Cortex-M0+ running at 64 MHz and it uses 64 KB of RAM. Comparatively, the BlueNRG-1 and BlueNRG-2 rely on a Cortex-M0 at 32 MHz and 24 KB of RAM. The new device also has a one-time programmable memory area for security purposes.
