If you’re having librtlsdr import errors: (or higher powers of two) samples at a time if you have problems. Some operating systems (Linux, OS X) seem to result in libusb buffer issues when performing small reads. It’s a simple process if there’s an additionalįunction you need to add support for, and please send a pull request if you’d like to share your changes. There are a few remaining functions in librtlsdr that haven’t been wrapped yet. Note that these binaries may have additional dependencies. Should be in the pyrtlsdr directory, or a system path. The librtlsdr binaries (rtlsdr.dll in Windows and librtlsdr.so in Linux) Matplotlib is also useful for plotting data. Optional: NumPy (wraps samples in a more convenient form) If this is set, no other modules will be available. On platforms where the librtlsdr library cannot be installed/compiled, it is possible to import the RtlSdrTcpClient only by setting the environment variable 'RTLSDR_CLIENT_MODE' to 'true'. # On another machine (typically) client = RtlSdrTcpClient ( hostname = '192.168.1.100', port = 12345 ) client. It also requires the new async/ await syntax introduced in Python 3.5+. Note that the rtlsdraio module is automatically imported and adds stream() and stop() methods to the normal RtlSdr class. See the respective modules in the rtlsdr folder for more details and feel free to test and report any bugs! rtlsdraio  Two new submodules are available for testing: rtlsdraio, which adds native Python 3 asynchronous support (asyncio module), and rtlsdrtcp which adds a TCP server/client for accessing a device over the network. To a custom value by using the rtl_eeprom utility packaged with librtlsdr. Most devices by default have the same serial number: ‘0000001’. get_device_index_by_serial ( '00000001' ) sdr = RtlSdr ( device_index ) # Or pass the serial number directly: sdr = RtlSdr ( serial_number = '00000001' ) Note 

get_device_serial_addresses () # Find the device index for a given serial number device_index = RtlSdr. Examples  Simple way to read and print some samples: įrom rtlsdr import RtlSdr # Get a list of detected device serial numbers (str) serial_numbers = RtlSdr. Some documentation can be found in docstrings in the latter file. Pyrtlsdr can be installed by downloading the source files and running python setup.py install, or using pip andĪll functions in librtlsdr are accessible via librtlsdr.py and a Pythonic interface is available in rtlsdr.py (recommended). It wraps many of theįunctions in the librtlsdr library including asynchronous read supportĪnd also provides a more Pythonic API. Pyrtlsdr is a simple Python interface to devices supported by the RTL-SDR project, which turns certain USB DVB-T donglesĮmploying the Realtek RTL2832U chipset into low-cost, general purpose software-defined radio receivers.
