Remote Control with WM Smartphone
This howto describes how to use your Windows Mobile 5 Smartphone as remote control for your MythBox.
- 1 Introduction
- 2 Installation
- 3 Using MythControl
- 4 Tips and Tricks
I started this project after my old Palm m500 finally broke after I have been using it as remote control for my MythBox a couple of years with OmniRemote. I bought a new Windows Mobile 5 Smartphone and started some experiments to use its Bluetooth capabilities to control MythTV. The result is a project which I called MythControl and that consists of a little server application running on the MythBox and a Windows Mobile 5 Smartphone remote control application.
After I got it running, it turned out to work better than I thought and way better than the Omniremote solution.
- Since it uses Bluetooth, you don't have to point the remote directly at the IR receiver, instead you can even use it in a different room!
- The reaction is way faster than an infrared solution, it feels more like using a keyboard.
- The keys of the smartphone are more convenient to press than any touchscreen.
And with the remote control being completely customizable, I found this to be a perfect remote for my MythBox.
First, we have to pair your bluetooth smartphone with your Linux box, then we can install the server application and the smartphone remote control.
Preparing Bluetooth Installation
For two Bluetooth devices to be able to communicate, they have to get paired first. This is just a very short description on howto pair your smartphone with your Linux box, please refer to the Bluetooth documentation for your Linux distribution for more details. A howto for Gentoo Linux can be found . Please make sure to include Rfcomm in your setup.
You need to have the Bluez tools and development libraries are installed. I use Bluez version 3.7, I can't tell if it works for any other version.
Check your Bluetooth device on your Linux box.
A call to 'hciconfig' should return something like:
# hciconfig hci0: Type: USB BD Address: 08:00:17:1B:42:96 ACL MTU: 339:4 SCO MTU: 60:9 UP RUNNING RX bytes:5603 acl:177 sco:0 events:209 errors:0 TX bytes:40682 acl:270 sco:0 commands:30 errors:0
If no Bluetooth device is being displayed, please check your Bluetooth Dongle, your Bluetooth kernel configuration and your distribution specific Bluetooth startup.
Put your Bluetooth device in 'Discoverable' mode.
# hciconfig hci0 piscan
Start the passkey-agent to set the passkey.
# passkey-agent --default 1234 &
Please replace 1234 with the pairing pin you are going to use. You will have to enter the same pin in your mobile phone in the next step. Since this is the only security precaution, please make sure not to choose something simple!
Offer a RFCOMM serial port emulation on your Linux box.
# sdptool add --channel=3 SP
Please configure your system to execute this command during bootup after the Bluetooth subsystem has been started.
Now it's time to pair your smartphone with the linux box. On your WM5 smartphone, go to Settings->Connections->Bluetooth. Make sure Bluetooth is activated and go futher to Menu->Devices. The phone lists the devices know to it. If your box has never been added before, go tho Menu->New. The smartphone now scans for devices in the area. Your MythBox should show up in the list after the scanning has finished. Select your MythBox and press 'Next'. The phone will now prompt you for the passkey. Enter the passkey you specified for the passkey-agent above and press 'Next' again. A confirmation message will be displayed.
Goto Settings->Connections->Bluetooth again and select Menu->COM Ports this time. Select Menu->New Outgoing Port. Your MythBox should now show up in the list. Select it and specify a port on the next screen (default is COM6). Press Done.
You can now proceed with the MythControl installation.
