Hello, welcome to the “Practical Low Cost Bare-Metal Bluetooth Development” course.
As the name implies this course teaches you how to develop bare-metal drivers and libraries for the popular low-cost Bluetooth chips currently on the market.
In this course we cover chips across all Bluetooth protocols: Bluetooth Classic, Bluetooth 4.0 (BLE), Bluetooth 5.0(BLE).
The primary objective of this course is to give you the skillset to professionally develop bare-metal Bluetooth enabled firmware. This is an important course in our embedded wireless development series.
In this course we shall develop bare-metal drivers and libraries ...

....for the following low-cost Bluetooth chips:

  • HC-06: Bluetooth Classic
  • HC-05: Bluetooth Classic
  • JDY-08: Bluetooth Low Energy (BLE) 4.0
  • HM-10: Bluetooth Low Energy (BLE) 4.0
  • HM-19: Bluetooth Low Energy (BLE) 5.0

So with that understood, let me tell you…

Exactly What You’re Getting

This course can be divided into 4 major sections.

First Section

The first section is theoretical. In this section we shall learn about the Bluetooth protocol, its history, and the key differences amongst the various protocols. We shall also compare our selected Bluetooth chips across different parameters so that you will know the right chip to use for a particular use case.

Second Section

In the second section we shall develop bare-metal drivers for interfacing the Bluetooth chip to our STM32 microcontroller. We shall navigate the microcontroller’s reference manual and datasheet to extract the right information to build these drivers.

Third Section

After developing our drivers for interfacing the Bluetooth chip to our STM32 microcontroller, we shall go a head and develop efficient data structures for managing communication between the Bluetooth chip and our microcontroller.

Last Section

In the last section, we shall combine the drivers and data structures developed in the previous sections to develop a library for each of our Bluetooth chips.

We shall then go on to use the library to develop Bluetooth enabled firmware applications such as:
  • Sending data over Bluetooth from an STM32 slave device to a mobile phone master device
  • Sending data over Bluetooth from an STM32 master device
  • Receiving data over Bluetooth from an STM32 slave device
  • Receiving data over Bluetooth from an STM32 master device
  • Communicating wirelessly between two STM32 microcontrollers using Bluetooth classic
  • Communicating wirelessly between two STM32 microcontrollers using Bluetooth Low Energy (BLE)
  • Controlling hardware modules by Bluetooth
  • Sending sensor data periodically over Bluetooth with a Realtime Clock (RTC)
  • Sending sensor data over Bluetooth with RTC triggered alarm.

As always, no copy/paste. We write each line code from scratch.
