Renesas Electronics can offer solutions corresponding to Bluetooth® low energy technology.


You can select a chip or a module.
IC(RL78/G1D)
Chip (RL78/G1D)

The chip incorporates a balun element and a filter. It is only required to connect the chip to an antenna. Reduction in the number of external components leads to reduction in labor required for design and quality control. It also supports the long-term product supply program.

Software
Bluetooth® low energy Protocol Stack

The Bluetooth® low energy protocol stack is software required to operate the G1D. It supports modem configuration and embedded configuration. It can also offer various profiles created by Bluetooth SIG. Of course, it can also adapt to custom profiles created by customers.

We offer Bluetooth® low energy software solutions corresponding to a wide variety of application development. For more information, please see Software Details.

Development Support Tools
Quick Start Guide

A Quick Start Guide for using the RL78/G1D Evaluation Board is available. It describes the procedure from the installation of the Renesas Electronics Bluetooth® low energy software up to its actual operation.

GUI tools

Even if you are not familiar with BLE, you can easily conduct BLE communication using GUI tools without writing a program. You can confirm the API execution procedure and the setting values for various parameters while actually conducting communication activities. Additionally, you can also develop a program smoothly while referring to the results (logs) of the operation check.

GUI tools
iOS/Android Application "GATTBrowser"

The smartphone application, "GATTBrowser" can be downloaded from App Store/Google Play.
GATTBrowser is the app to check the BLE behavior. It can scan BLE devices which are advertising in vicinity and can perform the GATT-based communication with the connected BLE device. You can easy to check the sample application behavior. GATTBrowser assist you to development of RL78/G1D device.

Examples of Applications/Examples of Utilization Technologies


Applications

Applications using the Bluetooth® low energy technology have started to be used widely in healthcare devices, and the use of the Bluetooth low energy technology is still expanding in a wide variety of applications for sports and fitness devices, smart home devices, industrial devices, beacon applications, etc.

Bluetooth ® low energy

Beacons are applications which continue to transmit ID/URL/vendor information for advertisement notification to smartphones and location detection through smartphones. As beacons must always continue to transmit radio waves, the most important thing is to operate them with low power consumption. Renesas offers stack exclusively for beacons, specialized in lower power consumption.
