Bluetooth Low Energy Protocol Stack for the RA 32-Bit MCUs

Available sample programs:

示例程序 概述
RA4W1 Group Apple Notification Center Service (ANCS) Sample Application (ZIP | English, 日本語) The ANCS sample application operates on the evaluation kit EK-RA4W1 and connects to iOS devices via Bluetooth LE wireless communication.
RA family BLE sample application (ZIP) These sample programs can work on evaluation kit EK-RA4W1 or user’s custom board. They can use a custom profile to change the blink rate of LED mounted on the board from remote device (e.g. smart phone) and send notification by pushing switch mounted on the board to remote device via Bluetooth LE wireless communication.
RA4W1 Group - High Data throughput sample application (ZIP | English, 日本語) This sample application uses LE 2MPHY to realize high data throughput Bluetooth LE wireless communication between one pair of evaluation kit EK-RA4W1. Both server and client side demo projects are provided.
RA4W1 group Environmental sensor network solution control sample software for building / HVAC (ZIP | English, 日本語) This software is an environmental sensor network solution control sample software for building / HVAC using RA4W1, ZMOD4410 (IAQ), HS3001 (Humidity & Temp. Sensor). By using this software, it is possible to collect IAQ (air quality) and humidity & temperature information of multiple devices via Bluetooth LE wireless communication. By using this sample software, you can easily build an environmental sensing system suitable for building / HVAC.

Bluetooth Mesh Stack:

The Bluetooth Mesh stack is provided by FSP v3.6.0 or later, 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.

Please refer to the following application notes for how to develop a Mesh application.

Basic Composition of Bluetooth Mesh Network

Available sample programs:

示例程序 概述
RA4W1 Group Bluetooth Mesh sample application (ZIP | English, 日本語)

By using the Mesh network, it will be possible to transmit data over long range, easily expand the network, and build a network that is resistant to communication failures. The demo program included in this sample application can execute the four phases of Bluetooth Mesh (Provisioning, Configuration, Model Communication, and Node Removal).
Please refer to the "Bluetooth Mesh Startup Guide" below for a Mesh demo program and a Mesh Mobile application operate on your smartphone.
RA4W1 Group Bluetooth Mesh Startup Guide (ZIP | English, 日本語)

This startup guide explains how to introduce Bluetooth Mesh using the Bluetooth Mesh stack. As sample code, a mobile application "MeshMobile (Mesh Mobile)" that operates as a Provisioner and Configuration Client for Bluetooth Mesh wireless communication on a smartphone is included. A suite of build environments for Mesh Mobile apps (a suite of project for Android Studio + a suite of project for Xcode) is included, so you can use it as a development base for Bluetooth Mesh applications for smartphones.

In addition, you can also easily evaluate Bluetooth Mesh communication operation with the RA4W1 by installing the MeshMobile from the application store.
