Using Bluetooth With The Raspberry Pi

The following instructions show how to setup and use a USB Bluetooth adapter with the Raspberry Pi. Please note that these instructions only apply to the latest Raspbian Jessie distribution. If you are using a different distribution or an older Raspbian build such as Wheezy some of the instructions will need to be changed as the Bluetooth stack and utilities have changed with the Jessie release and BlueZ 5.23.

A lot of the instructions I found online were relating to the older wheezy builds and it took some extra time to find the correct way to do things with Jessie. There were also a few configuration changes that needed to be made in order to work around some known issues/bugs relating to the RFCOMM (serial over Bluetooth) communication on the Pi. I have documented all this and hopefully I can save you some time if you are trying to do a similar things.

I am using a USB Bluetooth 4.0 adapter with a Broadcom BCM20702 chipset but there are many other supported Bluetooth adapters including those with CSR (Cambridge Silicon Radio) chipsets. I tested on a Raspberry Pi 2 but all this should work with any version of the Raspberry Pi as long as you are running the latest Raspbian Jessie distribution.

First make sure your Pi is up to date:

> sudo apt-get update > sudo apt-get upgrade > sudo rpi-update > sudo reboot 

Insert your USB Bluetooth adapter into one of the USB ports on the Pi and enter:

You should see output similar to the following:

If you used an adapter with a different chipset like CSR you might see ‘Cambridge Silicon Radio’ insead of ‘Broadcom Corp’. If you do not see something similar to this it might mean that there is something wrong with your adapter or it is not recognized/supported.

Next install the bluez and bluetooth manager packages:

> sudo apt-get install bluetooth blueman bluez python-gobject python-gobject-2 

Now you can check you your adapter state:

You should see output similar to the following:

BD Address: XX:XX:XX:XX:XX:XX UP RUNNING PSCAN ISCAN 

The [XX:XX:XX:XX:XX:XX] part is the MAC address of your Bluetooth adapter If you do not see «UP RUNNING» enter the following to turn on Bluetooth:

Part 2. Paring and Connecting Devices

Start the command line Bluetooth manager

You should see a line similar to:

Controller XX:XX:XX:XX:XX:XX raspberrypi [default] 

‘raspberrypi’ is the default name you will see when pairing/connecting to the Pi from other devices

Setting up Raspberry Pi 4 Wi-Fi and Bluetooth

The Raspberry Pi 4 Model B has an integrated Wi-Fi and Bluetooth adapter. You can set up the Raspberry Pi 4 Wi-Fi on the desktop, as well as on the console. With the same price as the predecessor models, you can save the money for a USB adapter with a Raspberry Pi 4 and ideally have two more USB ports at your disposal.

I will show in this tutorial how easy it can be to set up the Raspberry Pi 4 Wi-Fi and Bluetooth devices such as keyboards or mobile phones.

The Raspberry Pi 4 Wi-Fi can be set up easier than ever.
None of the previous Raspberry Pi models had the wireless receiver integrated, so you had to get a compatible USB stick and update it. This is still possible in principle, but the process has now become much simpler and can take place completely via the graphical user interface (GUI).

Updating the Raspberry Pi 3 / 4 Raspbian

If you’re using a fresh micro SD card, you can save yourself some update steps by downloading the latest Raspbian / Raspberry Pi OS version and transferring it to the SD card. If you already have a micro SD card with a version of Raspbian, it must be updated so that the appropriate packages are loaded, because without them the modules are not usable. As the downloads on the Foundation’s website are not updated weekly, updating to the latest version of Raspbian definitely makes sense.

To update the repositories we open the terminal and enter the following commands (internet connection must exist, for example via an ethernet cable):

sudo apt-get update sudo apt-get dist-upgrade sudo apt-get upgrade sudo rpi-update

The last command is only important for those who have not updated their packages for a very long time. Alternatively, you can also use sudo raspi-config to perform a system update. Updating may take a little while, depending on when the last time you updated.

Setting up Raspberry Pi 3 / 4 Wi-Fi

If you are directly connected to the keyboard and a mouse, you can start the desktop and see the Wi-Fi button in the top right corner of the taskbar. Clicking on it will show all of the available wireless networks in the area that you can connect to:

If you are connected to the Pi via SSH connection from your desktop computer, you can also follow this tutorial. In it, I show how to set up a wireless connection without the help of the GUI.

Setting up Raspberry Pi 4 Bluetooth

In order to use the integrated Bluetooth adapter of the Raspberry Pi 4, a few tools must be installed. So open the console again and enter the following:

sudo apt-get install pi-bluetooth sudo apt-get install bluetooth bluez blueman

The second line installs packages to control the Bluetooth module via the graphical interface. At the top left should also be a Bluetooth symbol visible after a reboot ( sudo reboot ).

Now you can connect the Pi with other devices (such as Bluetooth mouse, smartphones, etc.) and transfer files if necessary.

If you also want to automatically share files over the Bluetooth connection and integrate them into your programs, I showed in a previous tutorial how to set up a Bluetooth connection to the smartphone via the console.

A review from a customer on amazon.

“I have used this with a Raspbian pi install and I was impressed with out well it worked out of the box. Fast speeds and I was happy to see how well it worked for the price!

Had some issues connecting to a hidden SSID and while I’m still trying to figure out if that’s software or hardware it’s not enough to remove a star.

Definitely get this if you’re looking to add Bluetooth and WiFi to your rPi”
