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.

ARDUINO BLUETOOTH DONGLE TUTORIAL HOW TO

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.You should be able to see the text on the phone. Input some text back to the phone on Raspberry Pi.

You should be able to see the text on Raspberry Pi’s serial terminal.Ħ-2. Connecting Serial Terminal on Raspberry Piĥ-1. Open another terminal and launch the serial terminal. If everything goes well and the connection is established, you should be able to see like this: $ sudo rfcomm watch hci0Ĭonnection from XX:XX:XX:XX:XX:XX to /dev/rfcomm0ĥ. In the app, go to “Device” menu and select Raspberry Pi.

Install and launch “Serial Bluetooth Terminal” app on the phone.Ĥ-3. Listen for incoming connection on Raspberry Pi. You should be able to see something like below. On the phone, scan for Raspberry Pi and pair. Enter below in order to be discovered from the phone. To establish a connection, Raspberry Pi and the phone need to be paired.ģ-2. ExecStartPost=/usr/bin/sdptool add SPĢ-4. Add a line below immediately after “ExecStart” line, then save and close the file. ExecStart=/usr/lib/bluetooth/bluetoothd -CĢ-3. Look for a line starts with “ExecStart” and add compatibility flag ‘-C’ at the end of the line. Open Bluetooth service configuration file. In order to use SPP, Bluetooth service needs to be restarted with ‘compatibility’ flag.

Install a serial terminal application on Raspberry Pi.

Prerequisites (parentheses indicate my environment)

D-bus API (please see this post for this option).

This post shows steps for the 1st option (sdptool). There are two options to enable it in BlueZ (which is the default Bluetooth stack in Linux).

ARDUINO BLUETOOTH DONGLE TUTORIAL ANDROID

The goal is to establish SPP connection between Raspberry Pi 3 and Android phone, then send/receive text using serial terminal applications on both ends. This post shows steps to set up Bluetooth Serial Port Profile (or SPP) on Raspberry Pi.
