LimeSDR Getting Started Quickly | LimeSDR上手指南

0x00 概览

LimeSDR部分特性： USB 3.0 ； 4 x Tx 发射天线接口 6 x Rx 接收天线接口；

可用于Wi-Fi, GSM, UMTS, LTE, LoRa, Bluetooth, Zigbee, RFID等开发测试环境中。

RTL电视棒、HackRF、BladeRF、USRP、LimeSDR参数对比表：

HackRF One的价格，性能参数却能跟BladeRF甚至USRP媲美！

LimeSDR核心组件：

先上几张特写：

主板长10cm，算上USB接口11.5cm：

主板宽5.7cm:

相对于HackRF、BladeRF、USRP这三款主流SDR硬件（USRP mini除外），体积已经很小巧了。LimeSDR其体积实测只有一个iPhone5s的体积大小！

当插上USB供电后，除了上图显示的两颗绿色LED灯，还有一颗一闪一闪的红色LED灯也在工作。

接下来将分一键快速安装和源码编译安装来使用LimeSDR硬件，推荐使用源码编译安装。

0x01 Mac OSX

1.1 搭建开发环境

Mac OSX当中强烈推荐通过Mac Port 搭建SDR环境，配合源码编译达到最佳效果。

1.通过AppStore安装Xcode https://itunes.apple.com/cn/app/xcode/id497799835?mt=12

2.下载安装 XQuartz/X11 http://xquartz.macosforge.org/landing

3.下载安装 MacPorts https://trac.macports.org/wiki/InstallingMacPorts

sudo port search sdr

LimeSDR Getting Started Quickly | LimeSDR上手指南-LMLPHP

sudo port install rtl-sdr hackrf  bladeRF uhd gnuradio gqrx gr-osmosdr gr-fosphor

完成之后便可从GayHub上clone源码并进行编译安装。

1.2 源码编译LimeSuite

git clone https://github.com/myriadrf/LimeSuite.git

cd LimeSuite

mkdir builddir && cd builddir

cmake ../

make -j4

sudo make install

1.3 源码编译UHD驱动&&增加UHD对LimeSDR的支持

jocover基于UHD给LimeSDR开发了LimeSDR的驱动支持OpenUSRP，把LimeSDR来模拟成USRP B210来使用。

git clone https://github.com/EttusResearch/uhd.git

cd uhd/host/lib/usrp

git clone https://github.com/jocover/OpenUSRP.git

echo "INCLUDE_SUBDIRECTORY(OpenUSRP)">>CMakeLists.txt

mkdir build && cd build

cmake ..

make -j4

sudo make install

1.4 添加环境变量

echo 'export UHD_MODULE_PATH=/usr/lib/uhd/modules' >> ~/.bashrc

如果用的是iTerm2+zsh则执行：

echo 'export UHD_MODULE_PATH=/usr/lib/uhd/modules' >> ~/.zshrc

1.5 检测LimeSDR模拟USRP是否成功:

LimeSDR模拟成USRP B210之后最终的效果跟USRP是一样的：
