To use the RX23W Bluetooth feature, a protocol stack conforming to the Bluetooth specification is required. Also, the Bluetooth-compliant profiles and mesh software enhance your Bluetooth product interoperability in a wide application area.

Bluetooth Low Energy Protocol Stack Basic Package

Bluetooth Low Energy protocol stack basic package includes Bluetooth v5.0 compliant protocol stack library, API reference document for using the library and an application demo project for operation check.

The Bluetooth Low Energy Protocol Stack (RX) provides three types of libraries. The Bluetooth features you need is selectable by each feature set. The All features set supports all Low Energy (LE) specifications in Bluetooth Core Specification v5.0.
