or
[edit] Raspberry Pi
[edit] Software
AIS4Vera plugin [to be published]
[edit] Installation on Raspberry Pi
[edit] Set up Raspberry Pi
Download latest Raspian image from: http://www.raspberrypi.org/downloads Write Raspian image to SD card. Boot and login. sudo apt-get update sudo apt-get upgrade Expand rootfs (sudo raspi-config), then reboot (shutdown -r now).
[edit] Install Software Defined Radio
Based on: http://tubbyaustin.blogspot.de/2013/03/compiling-rtlfm-on-raspberry-pi.html sudo su - apt-get update apt-get install git git clone git://git.osmocom.org/rtl-sdr.git apt-get install libusb-dev libusb-1.0 libtool cmake apt-get install build-essential cd rtl-sdr/ mkdir build cd build cmake ../ make make install ldconfig cd .. cp rtl-sdr.rules /etc/udev/rules.d/ Blacklist the kernel module dvb_usb_rtl28xxu by adding the line blacklist dvb_usb_rtl28xxu to /etc/modprobe.d/raspi-blacklist.conf and reboot. Plug in DVB-T stick. Test the installation: rtl_test -t output: Found 1 device(s): 0: Generic, RTL2832U, SN: 7777XXXXXXXX Using device 0: Generic RTL2832U Found Rafael Micro R820T tuner Supported gain values (29): 0.0 0.9 1.4 2.7 3.7 7.7 8.7 12.5 14.4 15.7 16.6 19.7 20.7 22.9 25.4 28.0 29.7 32.8 33.8 36.4 37.2 38.6 40.2 42.1 43.4 43.9 44.5 48.0 49.6 Sampling at 2048000 S/s.

[edit] Install startup script
Based on: http://forum.aishub.net/ais-decoder/ais-decoder-beta-release/msg12766/?PHPSESSID=4krr2m8bouu59k146004vov733#msg12766 sudo apt-get install socat Start AIS decoder and relay AIS messages from UDP port 10110 to TCP server at port 2702: mkfifo /tmp/aisdata rtl_fm -f 161966899 -g 40 -s 48k -r 48k /tmp/aisdata & ./aisdecoder/build/aisdecoder -h 127.0.0.1 -p 10110 -a file -c mono -d -f /tmp/aisdata 2>> AIS_data.log & socat TCP-LISTEN:2702,fork UDP-LISTEN:10110 &
[edit] Install A4V Luup plugin
Extract plugin files, upload plugin files to Vera, create device: Description : A4V Upnp Device Filename: D_A4V.xml Ip Address : <Raspberry Pi's IP address> Reload Luup engine. TCP port 2702 is hard-coded in D_A4V.xml and cannot be changed without changing D_A4V.xml (and don't forget to adjust your startup script).
