The RYZ012x1 is a highly integrated wireless communication module that provides a pre-certified solution for Bluetooth® 5.0 Low Energy (LE). The network stack is executed inside the module, so there is no need for external stack operation. The module is available in two configurations (RYZ012A1 and RYZ012B1) with or without a mounted antenna. This allows for implementation flexibility and the option for longer wireless range requirements. For easy system creation, the module supports a pre-defined serial communication interface minimizing software effort and flattening the Bluetooth LE learning curve. Supported by the RA MCU family’s Flexible Software Package (FSP) and the QE for BLE tool, customers can focus on application development without dealing with the details of Bluetooth LE.

RYZ012 Certified Bluetooth 5.0 LE Modules

Shorten your time to market with these turnkey certified Bluetooth LE modules for IoT solutions.

GATTBrowser - iOS/Android Application

The GATTBrowser smartphone application can be downloaded from the Apple App Store and Google Play. The GATTBrowser app is used to check Bluetooth LE behavior. It can scan LE devices which are advertising in the vicinity and can perform GATT-based communication with the connected LE device. You can easily check the sample application behavior. GATTBrowser assists in the development of products that implement the Renesas Bluetooth LE MCU and module.
