How To Turn Any Device Into a Bluetooth Receiver Using Raspberry Pi
One of the most versatile microcomputers on the planet is the Raspberry Pi.The community and developers constantly upgrade the computers and make them cheaper.Many older devices don't come with the ability to link up your device to play music.The majority of devices come with an AUX port.With the code provided in the article and some time, you can have any device in your house ready to be connected to the internet.The code for each step is provided at the bottom of the article.
Step 1: You can download the latest version of Raspbian from the website.
You need to download win32 disk imager to register the file as an operating system.The image file on your desktop should be the Raspbian file.Before you copy the file over, make sure the letter for the micro SD card is correct.Plug the image into the Raspberry Pi and start it up.
Step 2: If you want to use the default password, use it for the pi.
If you want to connect via the internet, click on the icon at the top of the screen.Once you're done setting up, you don't need the internet anymore.Downloads are the only reason you will need the internet.
Step 3: The software is needed for this to work.
You can enter the code in the command terminal.The latest version of the software is downloaded by the code in line A.The code in line B allows a program called pulseaudio, which is an open source program that acts as a server, to broadcast sound to the device.We can start editing config files once the program is finished.Go to apt-get and install bluez pulseaudio-module.
Step 4: Adding the user pi to the device will allow you to play music.
The code can be entered from line A.This allows you to change the settings.The A2DP will be enabled in the bluetooth configuration.A2DP is a type of streaming that lets us connect to other devices.Since it can send more data faster, it's a higher quality connection.The code from line B should be used to open the config file.There is a smallUrl and a bigUrl on the website.
Step 5: The configuration file for Pulseaudio is the pulse daemon config file.
The code is from line A.You have to be able to convert the audio from different qualities so it can be used on your device to change the resampling method.Add at the beginning of the line to make it look like the code is in line B.Line C should be added below line B.There is a smallUrl and a bigUrl for the Step-5-Code.
Step 6: To have our devices connect, you will need to change some files.
We need to change the files.Add the code from line B to line A in the terminal.If the directory exists, you need to use the code from line C to create it.If "$ACTION" means "add", then the master 100% pacmd set-sink-volume 0 65537 will be added.echo pactl load-module module-loopback source to set bluez_source
Step 7: If we create another script that turns on and off bluetooth discoverability when it starts up, we can connect our device to the pi.
Enter the code from line A in the terminal.To create a new script, open up the text editor.The code from line B can be entered in the text editor.You can save the script and exit the text editor.If you give the text file execute permission, it will be able to be launched.When the pi boots up, make this script start.We need to enter the lines of code from C and D.
Step 8:
There is a smallUrl and a bigUrl for the Step-8- Code.If you want to get to that file, you need to enter the code from line A and look for the following line of code, add it and it won't be read by the program.It should look like the code in line B.You can add the code from line C.Save and exit below it.You are ready to go if you just restart the Pi.Go to the root of the machine and make sure it's the same as the one in A.Respawn:/sbin/ getty 115200 tty1 C.
