Identifikasi USRP

Device menggunakan alamat / address yang berupa pasangan string key / value. Pasangan parameter ini digunakan untuk mempersempit pencarian untuk device spesifik atau kelompok device.

Identifying USRPs

Devices are addressed through key/value string pairs. These string pairs can be used to narrow down the search for a specific device or group of devices. Most UHD utility applications and examples have an --args parameter that takes a device address, which is expressed as a delimited string.

See the documentation in types/device_addr.hpp for reference. Common device identifiers

Every device has several ways of identifying it on the host system: Identifier Key Notes Serial serial globally unique identifier Address addr unique identifier on a network Name name optional user-set identifier Type type hardware series identifier Device discovery via command line

Devices attached to your system can be discovered using the uhd_find_devices program. This program scans your system for supported devices and prints out an enumerated list of discovered devices and their addresses. The list of discovered devices can be narrowed down by specifying device address args.

uhd_find_devices

Device address arguments can be supplied to narrow the scope of the search. 

uhd_find_devices --args="type=usrp1"

-- OR -- 

uhd_find_devices --args="serial=12345678"

Device discovery through the API

The device::find() API call searches for devices and returns a list of discovered devices. 

uhd::device_addr_t hint; //an empty hint discovers all devices
uhd::device_addrs_t dev_addrs = uhd::device::find(hint);

The hint argument can be populated to narrow the scope of the search. 

uhd::device_addr_t hint;
hint["type"] = "usrp1";
uhd::device_addrs_t dev_addrs = uhd::device::find(hint);

-- OR -- 

uhd::device_addr_t hint;
hint["serial"] = "12345678";
uhd::device_addrs_t dev_addrs = uhd::device::find(hint);

Device properties

Properties of devices attached to your system can be probed with the uhd_usrp_probe program. This program constructs an instance of the device and prints out its properties, such as detected daughterboards, frequency range, gain ranges, etc...

Usage: 

uhd_usrp_probe --args <device-specific-address-args>

Naming a USRP

For convenience purposes, users may assign a custom name to their USRPs. The USRP can then be identified via name, rather than a difficult to remember serial or address.

A name has the following properties: 

   * is composed of ASCII characters
   * is 0-20 characters
   * is not required to be unique

Set a custom name

Run the following commands: 

cd <install-path>/share/uhd/utils
./usrp_burn_mb_eeprom --args=<optional device args> --key=name --val=lab1_xcvr

Discovery via name

The keyword name can be used to narrow the scope of the search. Example with the find devices utility: 

uhd_find_devices --args="name=lab1_xcvr"

-- OR -- 

uhd_find_devices --args="type=usrp1, name=lab1_xcvr"
