If you are planning to program your Blue Pill using UART, then please note that the same pins are being used for communication with the Bluetooth Module (Pins PA9 and PA10).Īnd if you are using USB Programming, then disconnect the Bluetooth Module form the STM32 Board, upload the program and reconnect the Bluetooth Module. the traditional UART based programming using USB to Serial Adapter or the USB Bootloader based programming through the on-board microUSB Port. Program STM32 Blue Pill using USB Port – “ How to Upload STM32F103C8T6 USB Bootloader?“Īlso, you can use either of the programming methods i.e. Introduction to STM32F103C8T6 – “ Getting Started with STM32F103C8T6 Blue Pill“ Hence, I suggest you to completely go through the previous tutorials mentioned below before proceeding further with this project. I won’t be discussing those topics again. In the previous STM32 Tutorial, I have discussed the basics of STM32F103C8T6 Blue Pill board and also how to upload program through the USB Port of the board. ![]() In this project, I will be focusing on Interfacing HC-05 Bluetooth with STM32F103C8T6 Blue Pill Board. So, I suggest you to refer to that tutorial for additional information on HC-05 Bluetooth Module. For example, in the “HC-05 Bluetooth Module” Tutorial, I have talked a deal about some basic information regarding the HC-05 Bluetooth Module, its layout on the board, its pins description and also demonstrated how to interface HC-05 Bluetooth Module with Arduino. I have already implemented several HC-05 Bluetooth Module based projects. It is a simple UART based module that runs at the traditional 2.4GHz wireless frequency for a range up to 10m. In fact, with the development of BLE (Bluetooth Low Energy), the development and implementation of Bluetooth based wireless headsets is at its peak (sorry 3.5mm headphone jack fanboys, myself included!).Ĭoming to the Embedded World, the HC-05 Bluetooth Module is the most popular Bluetooth Modules being used for a long time. Even in consumer electronics like mobile phones and laptops, it is commonly used for data transfer and audio functionalities. Interfacing HC-05 Bluetooth with STM32F103C8T6īluetooth is one of the most popular wireless communication protocols used in embedded systems. ![]()
