Bluetooth Application Development with BlueZ Training Workshop

Bluetooth Application Development with BlueZ Training Workshop

Bluetooth Application Development with BlueZ Training Workshop is a 2-day training program focuses on Bluetooth, BLE and BlueZ development including classic Bluetooth, Bluetooth Low Energy (BLE), Bluetooth 5.02 new features, application, architecture, protocol stack, and development with BlueZ.

Participants will learn about BlueZ, the Bluetooth stack for Linux. Its goal is to program an implementation of the Bluetooth wireless standards specifications for Linux.  BlueZ stack supports all core Bluetooth protocols and layers. 

Intended Audience

Bluetooth Application Development with BlueZ Training Workshop is a technical course intended for engineers, software developers, V&V professionals, project managers, and other related job functions.
