Arm is launching the industry's first open-source, fully qualified and product-ready Bluetooth 5 Low Energy (BLE) software stack, giving developers more flexibility in developing new designs for the Internet of Things (IoT) with BLE wireless connectivity.
The Mbed Cordio Stack sits alongside a set of Mbed OS connectivity for Thread, Wi-Fi, 6LoWPAN, LoRa and cellular to provide the different options for flexible, secure and connected IoT designs.
According to the 2018 Bluetooth Market Update, there will be more than 5 billion Bluetooth device shipments by 2022, with 97% of them containing BLE. Bluetooth Mesh will also drive new market opportunities across building automation, sensor networks, and other IoT solutions.
Bluetooth 5 supports 2x the data rate, 4x the range and 8x the broadcast capability compared to the previous version, Bluetooth 4.2. The Cordio BLE stack is integrated with the free, open-source embedded operating system, Mbed OS so that 350,000 Mbed developers can access it and get forthcoming access to Bluetooth Mesh.
This also allows devices to be securely connected and managed through the Pelion IoT Platform,
For silicon partners, the solution gives them access to a full-featured, production-ready Bluetooth 5 stack as part of their Mbed OS offering and the ability to port to additional platforms. Having complete open source access to the stack removes the risk of relying on a stack vendor says Arm, and allows them to meet changing requirements where full source code availability is critical.
