Now let’s modify the permissions of the file to make it executable. Sudo chmod 774 /usr/lib/udev/bluetooth Great! Your Raspberry PI is now capable of playing Bluetooth audio via A2DP! Now let’s take it a step further by turning on discovery mode and auto accepting connections right when the PI logs into the command line automatically. You should stick a Raspberry Pi on it with a wifi card. Configure it with bluetooth and you could relay any music on someones phone over bluetooth and bam, now you can play music from the phone on the awesome speaker. Might need another panel. Raspberry Pi uses about 5w of power plus the bluetooth.

I used just around 1k USD for all of it.
If you have some materials like glue and screws you can save a bit. I spend around 110 USD on screws, glue, wires, fuses, etc.EDIT: I just got word about the import of the HP10W in America. They will likely cost around 45 USD which is A LOT cheaper than the 80 USD i pay in Denmark. If the rest of the materials have a similar pricetag, then you can do the math for the final assembly. Americans might just look at a final price around 600 USD then?Maybe some American can look up some material costs and post them here.
I plug it in. As you might have spotted i use some normal DC cables for easy connecting stuff. These cables happens to be so common that the powersupply for my external harddrive, which i never use, can fit in. Any DC converter that gives 12 to 19V will work.
I say 19V because i know that will work. According to spec sheets of the controller unit it should be able to handle anything up to 30V.I simply unplug the solar panels and connect the power supply there. So the controller thinks its getting power from the sun at a constant rate. This is done because i can then leave it in, since the controller will stop charging batteries at 13.5V to protect them.
Bluetooth is a wireless technology standard, and it has been a feature on the Raspberry Pi since the. You can use it to connect Bluetooth keyboards, mice, and other accessories: like speakers and headphones.The new even moves from Bluetooth 4.1 to 4.2, which brings faster and more reliable over-the-air data transmission.In this tutorial we’ll take a look at hooking up a Raspberry Pi to a Bluetooth speaker. This enables you to play music wirelessly from your Raspberry Pi, turning it into an effective media centre.You should be able to follow this Bluetooth audio tutorial with any Bluetooth-enabled Raspberry Pi.And Bluetooth can easily be added to an older Raspberry Pi using a dongle, like this.Play Bluetooth Audio on a Raspberry Pi: get some musicFirst, you’ll need some music files. You can stream audio online from a source such as YouTube, and many people have MP3 and other audio files. We downloaded for this tutorial. Save the file to your Music folder.
Use File Manager to locate the zip file, then right-click it and choose Extract Here.It is possible to play the music files directly from Terminal using omxplayer. Open a Terminal window and enter omxplayer followed by the path to the music file, like this. Oxmplayer / Music / AntonRothschild - 03 - ItsNotVegas. Mp3 But it’s not a great visual option.
We’d rather double-click MP3 files in the File Manager using the Desktop interface. For this we need a media player, and we’re going to use a popular one called VLC. Enter these commands in Terminal:sudo apt-get updatesudo apt-get upgradesudo apt-get install -y vlcDuring the installation you’ll be asked if you want to allow metadata network access. This is used to add cover artwork and track listings to your files. Tick or untick the box and click Continue.Double-clicking the MP3 files in File Manager will open VLC and play the file.
Connect to BluetoothOK, so we’ve got our music and a music player. Now it’s time to connect the Raspberry Pi to a Bluetooth speaker.To do this you’ll need to put the speaker in pairing mode and pair the Raspberry Pi to the speaker. How you do this depends on the speaker itself. If your speaker has an interface, you’ll probably use the controls to put it into pairing mode. Many smaller speakers or headphones have a button that you hold down to put the device into pairing mode (typically you’ll see a flashing light).Connect a Raspberry Pi to Google Home via Bluetooth. We’re using a Google Home speaker for this test. For this you simply say “Hey Google Connect To Bluetooth” (you can do the same with Alexa).
Now click on the Bluetooth icon in the top-right of the screen and choose Add Device.Look for your speaker in the ‘Add new device’ window. In most cases the speaker will be identified by an easily recognisable name, such as our Google Home. However, you may need to locate the device using its MAC address (the six octet hexadecimal code).
These are often printed on the device itself – or you can cancel pairing mode, then re-enter it and see which device disappears and reappears. Hopefully you won’t have to resort to that. Locate the speaker in Add Devices and click Pair. After a short while, the window will display Pairing Successful. Click OK. Your Raspberry Pi is now paired with the speaker, but it won’t output audio to it yet. Right-click on the Volume Control applet in the top-right of the screen and choose your speaker from the list (it is below Analog and HDMI).A pop-up will display ‘Connecting to Bluetooth audio device’.
Now double-click on of the music files in Files Manager. The VLC app will open and your music will start playing through the Bluetooth speaker.When you restart the Raspberry Pi, you will need to reconnect to the Bluetooth speaker (this isn’t the same as pairing – it is still paired). Click on the Bluetooth icon, choose your speaker, and select Connect from the menu.You can use the Bluetooth menu to disconnect, if you don’t want to use a device for the time-being.
