Have you bought a Bluetooth adapter for your BeagleBone Black but can’t get it to work? If so, this article is for you. I will show you how to easily enable Bluetooth on BeagleBone Black.
If you are having trouble getting your computer or other device to pair with the Bluetooth dongle you have attached to your BeagleBone Black, the fix may be as simple as this two step procedure. By default, the Bluetooth drivers are not fully enabled; I will show you how to fix this.
If you don’t care about learning what is going on, just copy and paste this command into your BeagleBone Black. I don’t really recommend doing this in general, if you get into the habit of just copying and pasting code from random websites on the internet, you could easily give someone fairly unrestricted access to your system. But if you can look at the commands below and understand what is going on, go for it.
echo –e “\n[Bluetooth]\nEnable=true” >> /var/lib/connman/settings && systemctl enable bluetooth.service && systemctl start bluetooth.service
If you would like to learn a little bit more about what you are doing and why, continue reading.
Step 1: Enable Bluetooth Capability
The first step in enabling Bluetooth is to inform your BeagleBone Black that you would like to be able to use this feature. To do this you will just need to make a quick edit to a configuration file.
If you perform:
You should see something like:
[global] OfflineMode=false [Wired] Enable=true [WiFi] Enable=true
What this file is essentially telling you is that the BeagleBone Black connection manager is only aware of Wired Ethernet connections, or WiFi connections enabled through a USB module. What you want to do is add the Bluetooth module. To add this just type the following command:
echo –e “\n[Bluetooth]\nEnable=true” >> /var/lib/connman/settings
Now if you look at your configuration file again by using
You should see something like this:
[global] OfflineMode=false [Wired] Enable=true [WiFi] Enable=true [Bluetooth] Enable=true
If this worked, then you can move on to the next step. If it did not work then try to do some troubleshooting. If you just can’t figure it out then leave me a comment below and I will help you out.
Step 2: Enable the Bluetooth System Service
Your next and final step is to enable and start the system service that monitors Bluetooth. This allows you to pair with the BeagleBone Black, as well as some other core functionality. To enable the service type:
systemctl enable bluetooth.service
You may see a few messages but should not get any errors, if that is the case then this step worked as expected and your BeagleBone Black is almost ready to use Bluetooth. All you need to do now is start this service using the following command.
systemctl start bluetooth.service
Congratulations! You should now have a working Bluetooth dongle. If you ran into problems along the way feel free to ask questions in the comments below, I will always do my best to help.
