Connect Bluetooth Headset Or Speaker

In this post, I’ll share with you the final solution that lets you connect your Bluetooth headset or speaker to Raspberry Pi 3.
You’ll be able to use both output speaker and input microphone.

By the way, thanks to the people who kept me updated in the comments, it was a long journey together (:

Firstly, let me sum up the root causes of this long time problem:

  1. Drop-out of ALSA support in Bluez v5 (replaced by PulseAudio).
  2. Unavailability of correct PulseAudio version for Raspbian Jessie.
  3. Incorrect audio rooting SCO-HCI for the Bluetooth chip BCM43438.

I solved the issues 1 and 2, but I couldn’t find a good solution for 3. For issues 1 and 2, I found how to install manually PulseAudio, with code sources, or using Debian backports. For issue 3, I used a BT-USB dongle that bypassed the internal Bluetooth chip and let me use A2DP and HSP profiles.

NordVPN Auto-Connect when Raspberry Pi Boots

This is a quick tutorial on how to start an OpenVPN connection when your Raspberry Pi system boots.

Do you need a VPN for Linux?

If you’re a Linux user, you’re probably aware that Linux is one of the most secure OS out there. It has a small but dedicated user base, it exists across multiple different distributions, it limits user admin privileges, and the open-sourced code is scoured by hawk-eyed developers looking for vulnerabilities to patch up. All of that is true, but that doesn’t mean a VPN isn’t still a vital tool for Linux users.

Raspberry PI: Connecting a Neo-6M  GPS Module

I built a project using a Neo-6M  GPS Module with the Raspberry PI. Now there are several USB solutions, and apps that work with them, but I wanted to show how to use a $20 GPS module with a a serial UART, and Python code to decode the NMEA strings. Then you can write your own GPS interface, or combine the data with Google Maps.

Hardware Setup:

The first step is to connect the GPS module to the Raspberry PI. There are only 4 wires involved, so it’s a simple connection.Read More

Connecting Wiimote Controllers to the Raspberry Pi

In this Raspberry Pi Wiimote controllers guide, we will walk you through the process of setting up a Wiimote on your Raspberry Pi and show you how to setup both cwiid and wminput.

Utilizing Wiimote controllers on the Raspberry Pi can be painful to deal with due to its handling of the Bluetooth stack. While they run over standard Bluetooth, their actual functionality is not picked up as a conventional joystick device like Xbox controllers and PlayStation controllers.

Instead to support the full functionality of Wiimote controllers in a way that most applications can support we must utilize two pieces of software.

These being cwiid and wminput. One acts as a library that interprets the Wiimotes actions into joystick actions, the other being somewhat of a driver that creates an input device that applications can utilize easily.Read More

Using PlayStation3 Controllers with the Raspberry Pi

If you have ever tried to utilize a PlayStation controller with the Raspberry Pi, you may have found it’s not very simple to do. The Raspberry Pi PlayStation controller guide will walk you through the process of setting up and connecting both PlayStation3 controllers and PlayStation4 controllers.

For PlayStation3 (PS3) controllers,I show you how to install the Six-pair Software and utilize it to set up your PS3 controller so it can connect to whatever Bluetooth device you are using on your Raspberry Pi.

In this PS4 controller tutorial we walk you through the process of pairing it with the Raspberry Pi’s Bluetooth and also offer alternative solutions if your controller doesn’t work with the standard Bluetooth stack. You can also set up Xbox controllers on the Raspberry Pi, as well as several other types of game controllers.

Setting up controllers is the perfect way to have your Pi ready to play some games. You might also be interested in using the controllers in other Raspberry Pi projects that make use of a gamepad.Read More
