Overview
Description
Bluetooth Low Energy (Bluetooth LE) Protocol Stack is a Bluetooth 5.0 qualified protocol stack that operates on RL78/G1D (optional functions added after Core Specification 4.2 are not supported). It is equipped API for realizing Bluetooth LE wireless communication and API for implement a custom profile. Moreover, it supports two types of system configurations (embedded and modem configuration).
Features
- Bluetooth LE Profile - Various profiles are available. It is also possible to correspond to customer-specific profiles.
- Virtual UART Application - Responding to demands for wireless serial communication and wireless communication between embedded modules, we have developed a virtual UART application that works with Bluetooth LE technology.
- For application development using a host microcontroller in modem configuration.
- For application development in a single device in embedded configuration.
- Host MCU Simple API - Simple API can control an RL78/G1D or RL78/G1D module (RY7011) from a host microcomputer with just 9 APIs, and can realize Virtual UART communication and beacon communication using Bluetooth LE wireless communication easily.
- Available IDEs: CS+ (CA78K0R Compiler/CC-RL Compiler), e2 studio (CC-RL Compiler), and IAR Embedded Workbench (IAR Compiler).

System Configuration/Modem Configuration
For Application Development Using a Host Microcontroller
For modem configuration, Bluetooth LE communication is realized via serial connection of a host microcontroller and RL78/G1D MCU. It is possible to flexibly respond to demands such as adding Bluetooth LE to an existing application. We also have host samples for Renesas microcontrollers. This enables the shortening of the development period.
