Software configeration
First update you Raspberry Pi wheezy Linux to the latest version.
sudo apt-get update
sudo apt-get install git
sudo apt-get install cmake
sudo apt-get install libusb-1.0-0.dev
sudo apt-get install build-essentialNow install the RTL-2832U USB dongle driver src and compile
git clone git://git.osmocom.org/rtl-sdr.git
cd rtl-sdr/
mkdir build
cd build
cmake ../ -DINSTALL_UDEV_RULES=ON
make
sudo make install
sudo ldconfig
Edit the following file /etc/modprobe.d/raspi-blacklist.conf
use your favourite editor like nano or vi
sudo vi /etc/modprobe.d/raspi-blacklist.conf
add the following lines in the file.
blacklist dvb_usb_rtl28xxu
blacklist rtl2832
blacklist rtl2830Save and exist
You need to reboot. so just run sudo shutdown -r 0
Run this command sudo rtl_test -t to test the compiled driver
Now you maybe see a error like this:
pi@raspberrypi ~/rtl-sdr/build $ rtl_test -t
Found 1 device(s):
0: Generic, RTL2832U, SN: =
Using device 0: Generic RTL2832U
usb_open error -3
Please fix the device permissions, e.g. by installing the udev rules file rtl-sdr.rules
Failed to open rtlsdr device #0.Need edit rtl-sdr.rules file
sudo vi /etc/udev/rules.d/rtl-sdr.rules
find the line and change it like this
SUBSYSTEMS=="usb", ATTRS{idVendor}=="0bda", ATTRS{idProduct}=="2832", MODE:="0666", GROUP="adm", SYMLINK+="rtl_sdr"now you re-run this command sudo rtl_test -t to test. In my case the output look like this:
pi@raspberrypi ~ $ rtl_test -t
Found 1 device(s):
0: Generic, RTL2832U, SN: 77771111153705700
Using device 0: Generic RTL2832U

No E4000 tuner found, aborting.To run the rtl server type rtl_tcp -a X.X.X.X , use you ip address of your Pi replace x.x.x.x.
Have Fun.
