Nordic nRF5x Bluetooth Low Energy (BLE) In-Depth Training
This training course provides in-depth technical exposure on the Bluetooth Low Energy (BLE) System on Chip (SoC) by Nordic Semiconductor. Namely, the nRF5x family (Both nRF52 and nRF51) which has nine chips options: nRF52840, nRF52833, nRF52832, nRF52811, nRF52810, nRF51824, nRF51822, nRF51802, and nRF51422. Many of these chips support multiple short-range wireless protocols; BLE, ANT, Thread/Zigbee through the 802.15.4 MAC, and 2.4Ghz propitiatory protocols; However, the main focus of this course is on Bluetooth Low Energy/Bluetooth 5 and Bluetooth Mesh. Nordic Semiconductor is one of the lead pioneers in the Bluetooth Low Energy sector. They have an estimate of about 50% of the global market share in BLE. Their chips are used in a wide spectrum of branded Bluetooth-enabled consumer electronic products worldwide, like the well-established Logitech wireless keyboards and mice. The training course is divided into three sections:
- Nordic nRF5x BLE In-Depth Training Course (Foundation Level): Step-by-step lessons and hands-on tutorials that covers all the essentials of the nRF5x SoCs hardware and software stack in-depth.
- Nordic nRF5x BLE In-Depth Training Course (Intermediate Level): Hands-on training which provides a clear, concise, and logical walk through of the Bluetooth Low Energy / Bluetooth 5 connectivity on the nRF5x SoCs.
- Nordic nRF5x BLE In-Depth Training Course (Advanced Level): This section of the course offers a comprehensive hands-on coverage of all aspects of Bluetooth Mesh protocol to create complex large-scale device networks based on the nRF5x SoCs.
Detailed course outlines and objectives for each section are below.
- Basic knowledge in the C programming language.
- Some experience in developing software for embedded systems.
Hardware: nRF52840 DK ,and nRF52840 Dongle. The Dongle is needed for the intermediate and advanced levels only. Different nRF5x boards can be used with some minor modifications.
Software: Segger Embedded Studio(SES) IDE, nRF5 SDK, Android Studio, nRF Connect, PuTTy. SES is the recommended IDE by Nordic Semiconductor for nRF5x firmware development, however, we can accommodate your preference of IDE.
Foundation Level Course Objectives:
