UHD Python API Installation and USRP Setup

To install the UHD Python API from source, Ubuntu 22.04 and Python 3.8 or higher are required.
Follow the steps below to compile UHD, install the Python bindings, and configure USB permissions for USRP B200/B210 devices.

---

Follow the commands exactly as given.

1. Install Dependencies

sudo apt update
sudo apt install -y \
    git cmake g++ python3 python3-dev python3-pip \
    libboost-all-dev libusb-1.0-0-dev libncurses5-dev \
    python3-mako libaio-dev

2. Clone the UHD Repository

cd ~
git clone https://github.com/EttusResearch/uhd.git
mv uhd uhd_repo

3. Build UHD From Source

cd ~/uhd_repo/host
mkdir build
cd build

cmake \
  -DENABLE_PYTHON_API=ON \
  -DPYTHON_EXECUTABLE=$(which python3) \
  -DPYTHON3_SITEPKG=/usr/local/lib/python3.10/dist-packages \
  ..

make -j$(( $(nproc) / 2 ))
sudo make install
sudo ldconfig

4. Install the UHD Python Module

cd ~/uhd_repo/host/build/python
sudo python3 setup.py install

If there are no errors, then the UHD module installed successfully

5. Configure USRP USB Permissions

USB 3.0/3.1 must be used for B210/B200 devices.

Copy the Ettus udev rule file:

sudo cp ~/uhd_repo/host/utils/uhd-usrp.rules /etc/udev/rules.d/

Reload udev rules:

sudo udevadm control --reload-rules
sudo udevadm trigger

Add current user to required groups:

sudo usermod -aG plugdev $USER
sudo usermod -aG dialout $USER

Reboot the system

sudo reboot now

6. Verify UHD Installation

After reboot:

uhd_find_devices

Expected output:

-- UHD Device 0 --
    serial: XXXXXXX
    product: B200
    type: b200

7. Verify Python UHD Bindings

python3 - << 'EOF'
import uhd
print("UHD Python API is working")
print("UHD Version:", uhd.get_version_string())
EOF

Expected output:

UHD Python API is working
UHD Version: 4.x.x
