  1. On the EV3, first verify that Bluetooth is powered on. In brickman, open the Wireless and Networks menu and select Bluetooth. Make sure the Powered checkbox is checked. The Bluetooth icon next to the battery in the status bar also indicates that Bluetooth is powered on. Furthermore, make sure the Visible box is checked to make the EV3 discoverable.

  6. On the EV3, find your Android in the list of Bluetooth devices and and select it.

     {% include /util/screenshot.html source="/images/brickman/bluetooth-droid4-selected.png" %}

  7. You should have a Network Connection button. Select it to open the network connection settings. (You can also find the connection in Wireless and Networks > All Network Connections.)

     {% include /util/screenshot.html source="/images/brickman/bluetooth-droid4-network-connection-selected.png" %}

     {% include /style/icon.html type="info" %} The Connect button pictured above is used to connect other Bluetooth services. It will not connect the network connection. We need to use Connect on the Network Connection screen below instead. {: .alert .alert-info}

  8. Then select Connect.

     {% include /util/screenshot.html source="/images/brickman/networking-droid4-connect-selected.png" %}

  9. State should change to Online. The Bluetooth icon will also indicate that you are connected and the IP address will be displayed at the top of the screen.

     {% include /util/screenshot.html source="/images/brickman/networking-droid4-connect-selected-online.png" %}

  10. For ssh access to the EV3 on Android, you can use an app called ConnectBot.

      Run ConnectBot and start a new connection. Do this by entering robot@<ip-address> where <ip-address> is the one seen on the EV3. Then press Enter on the keyboard to connect.

      {% include /style/icon.html type="info" %} Ignore root in the screenshot. It is from an older version of ev3dev. robot is the correct user name. {: .alert .alert-info}

  1. On the EV3, first verify that Bluetooth is powered on. In brickman, open the Wireless and Networks menu and select Bluetooth. Make sure the Powered checkbox is checked. The Bluetooth icon next to the battery in the status bar also indicates that Bluetooth is powered on. (Visible doesn't actually matter here.)

     {% include /util/screenshot.html source="/images/brickman/bluetooth-powered-visible-no-devices.png" %}

  2. On your host computer, open System Preferences and go to Bluetooth. This will make your host computer discoverable.

     {% include /util/screenshot.html source="/images/osx/10.10/System-Preferences-Bluetooth.png" %}

  3. On the EV3, select Start Scan on the Bluetooth menu. It should find your computer.

     {% include /util/screenshot.html source="/images/brickman/bluetooth-powered-my-computer.png" %}

  4. Select your computer from the menu and then select the Pair button.

     {% include /util/screenshot.html source="/images/brickman/bluetooth-my-computer-not-paired.png" %}

  5. Confirm the passkey on both devices when requested.

     {% include /util/screenshot.html source="/images/brickman/bluetooth-confirm-passkey.png" %} {% include /util/screenshot.html source="/images/osx/10.10/Pairing-Request.png" %}

  6. On your Mac, in System Preferences, go back and select Network.

     {% include /util/screenshot.html source="/images/osx/10.9/SystemPreferencesNetwork.png" %}

  7. If you do not already have a Bluetooth PAN device, click on the + icon in the lower left area to add a new network device. You'll need to select Bluetooth PAN in the drop down box. Click Create when you are done.

     {% include /util/screenshot.html source="/images/osx/10.10/System-Preferences-Network-Add-PAN.png" %}

  8. You may or may not see your EV3 listed next to Device: as shown. If you don't see it, don't worry, that is normal. Click Apply to save your changes, but don't connect yet. In fact, don't try to use the Connect button you see here. It is for [tethering] and won't work for the connection we are setting up here. Instead, we will initiate the connection from the EV3 itself later.

     {% include /util/screenshot.html source="/images/osx/10.10/System-Preferences-Network-Bluetooth-PAN.png" %}

  9. To share our Internet connection with the EV3. Go back to System Preferences and select Sharing.

  13. Select Connect here. You can also check the box for Connect automatically. This way you don't have to connect manually after you reboot.

      {% include /util/screenshot.html source="/images/brickman/networking-my-computer-0-connect-selected.png" %}

  14. State should change to Online to indicate that the EV3 has an Internet connection.

  1. The default Bluetooth and network settings in Ubuntu do not have support for this, so first you need to install blueman on your host computer.

     sudo apt-get install blueman
     

  2. Run the Blueman Bluetooth Manager.

     {% include /util/screenshot.html source="/images/ubuntu/16.04/blueman-manager-icon.png" %}

  3. On the View menu, select Local Services....

     {% include /util/screenshot.html source="/images/ubuntu/16.04/blueman-manager-view-local-services.png" %}

  4. Go to Network. Check Network Access Point (NAP) and dnsmasq. Change the IP address to 10.42.0.1 (this matches the old default from Ubuntu 14.04). For PAN support choose NetworkManager. DUN-support does not matter, we are not using it. Then click Apply and Close.

     {% include /style/icon.html type="info" %} If your EV3 is already paired, you will need to remove it and pair it again so that it will see the new network service. {: .alert .alert-info}

  7. You should now have a Network Connection button. Select it to open the network connection settings. (You can also find the connection in Wireless and Networks > All Network Connections.)
