Bluetooth Low Energy Protocol Stack for the RX Family

The Bluetooth Low Energy protocol stack is the software required to operate the RX23W MCU. It conforms to the Bluetooth v5.0 specification and all LE functions of Core Specification v5.0 can be supported. In addition, three types of libraries are provided depending on the function set, so that a configuration suitable for the specifications of the end product can be selected.

Bluetooth qualified 56 types (as of December 2019) of standard Profiles/Services are available.

The profile is generated from QE for BLE[RA,RE,RX]. You can also design and generate a custom profile. Renesas also provides sample programs as a reference for your program development. The sample programs will be further expanded in the future.

Available sample programs:

Bluetooth Mesh Stack:

The Mesh profile is provided as a dedicated library "Bluetooth Mesh Stack", so please use this to develop products that conform to the Bluetooth Mesh Networking specification. Bluetooth Mesh is a network optimized for building large-scale device networks, enabling multipoint-to-multipoint device communication. This technology is suitable for IoT solutions where performance, reliability, and security are important, such as building automation, sensor networks, and asset tracking.

Available sample programs:

Additionally, Renesas offers Bluetooth LE software solutions corresponding to a wide variety of application development. Refer the protocol stack product page for more information.

QE for BLE[RA,RE,RX] － Development Assistance Tool

The QE for BLE[RA,RE,RX] is a dedicated tool for developing embedded software in systems which support the Bluetooth Low Energy protocol stack. This solution toolkit runs in the e² studio integrated development environment (IDE). The combination of the e² studio and QE for BLE[RX] makes it easy to test the communications features of Renesas' RX23W Bluetooth LE microcomputer, thus reducing development periods for products being placed on the market. The standard profiles are generated from this tool. It can also design and generate the custom profile.

Please refer to the QE for BLE[RA,RE,RX]: Development Assistance Tool for Bluetooth Low Energy page for more information.
