Open the MuseHack app and press the connect button.
This will bring up a dialog box with a big ol scan button. Press it
The app will then begin to search for discoverable devices.
The new devices will appear at the bottom of the box. It will most likely have the name "null" or "HC-0X" with a 12 character address below it.
After selecting it, a pairing request will pop up.
Enter pin 1234
This is the factory set pin.
If the pairing screen did not come up, you may have to find it from the top pull-down menu or in the Bluetooth menu in your phone's settings.
Once paired and a socket has been made, the blinking light on the HC-05 will turn solid.
Plug the extender cable into your iPod.
After a few seconds, the MuseHack app screen should read the artist name, song name etc of the either the most recently played song or the first song from your entire library depending on how you last left the iPod.
If this does not happen please refer to the troubleshooting section.
If you built it successfully, plug your stereo into your iPod, blast it and celebrate saving the environment by not throwing away an iPod....or something.
Congrats. You're done.
Setting up the preferences can allow for auto connecting, auto pausing and alarm setting.
The Auto Connect is based on your connection to your home wifi.
Because constantly scanning for a discoverable Bluetooth device is resource expensive, the app will wait until your home wifi automatically connects before scanning for the previously chosen HC-05.
This can be setup by selecting the preferences option from the popup menu, tapping Auto Connect settings and checking the Auto Connect check box.
Doing this will make the next two selections available.
Make sure your wifi is turned on, tap Home WIfi Network and select your home network.
Once you have paired with an HC-05, you will have the option of selecting it from the list of other paired devices under the MuseHack Bluetooth Device option.
The Auto Play option below that will tell the iPod to play once it has established a connection.
The Auto Pause feature allows you to just up and leave without thinking about the music. If set, the music will continue to play from 1 minute to up to 30 minutes before pausing depending on your settings.
The Alarm feature allows you to set a time for when the music will begin to play. I have found it is much more pleasant to wake up when my favorite chill song hits the main speakers rather than an annoying stock alarm.
