Archive:Snapstream Firefly

The Snapstream Firefly is a X10 based remote control which uses RF commands as opposed to IR. This guide assumes that you have installed XBMC_Live or have at least performed all steps outlined in one of the articles listed here Installing_XBMC_for_Linux and here HOW-TO_setup_Lirc_to_talk_to_XBMC. You will also need a SSH client and a terminal emulator. I would recommend WinSCP and Putty as they work well and are free.

You will need root access for the following commands.

Setting up Lirc

First we will set up Lirc to work with the remote. lircd.conf specifies to Lirc how it should handle the remote device. We need to replace the current file with our Snapstream Firefly file.

• Replace the contents of /etc/lirc/lircd.conf in it's entirety with the following.

end remote 

Integrating Firefly into XBMC

You will need to add the following information into the current lirc map for XBMC to interperate the commands given by lirc into productive commands.

• Modify /etc/share/xbmc/system/Lircmap.xml to add the following directly below <lircmap> and above <remote device="mceusb">

<remote device="Snapstream">
<pause>pause</pause>
<stop>stop</stop>
<forward>forward</forward>

S3 resume combo Close button

The funny thing about this remote is that the only button which will allow it to resume the computer from standby via S3 switch is the same button that puts the computer into standby. The same command is issued by the remote every time you press the close button and is retained in memory until issued to a proper output device by lirc. Resuming from standby with the power button puts the computer back in standby or deactivates the remote.

In order to issue the S3 resume command to the computer and restart the remote controller without issuing the command to put the computer back into sleep mode or standby you will need to add the following resume script.

• Using your SSH client, create the file /etc/pm/resume.d/99lirc-resume.sh
• Modify the contents of /etc/pm/sleep.d/99lirc-resume.sh to contain the following

#!/bin/sh

case "$1" in
	resume)
		sleep 5
		sudo rmmod lirc_atiusb
		sudo modprobe lirc_atiusb
		sudo /etc/init.d/lirc restart >/tmp/resumescript.log

irw & sleep 1; killall irw >/tmp/resumescript.log

		sudo curl "http://127.0.0.1:8080/xbmcCmds/xbmcHttp?command=ExecBuiltIn&parameter=LIRC.Start" >/tmp/resumescript.log

echo "lirc_atiusb resume script completed" >/tmp/script.log

	;;
esac

You will now need to make the new file executable.

• open your terminal log in and type the following

sudo chmod +x /etc/pm/sleep.d/99lirc-resume.sh

• Restart the computer
