class mrpt::hwdrivers::CImpinjRFID

Overview

This class implements an interface to an Impinj RFID reader.

This object connects to a program that does the actual communication with the receiver. This is done because the manufacturer only provides libraries for C# and Java. The program that runs the device must be started after this object

#include <mrpt/hwdrivers/CImpinjRFID.h>

class CImpinjRFID: public mrpt::hwdrivers::CGenericSensor
{

    // construction

    CImpinjRFID();

    // methods

    void connect();
    virtual void doProcess();
    virtual void initialize();
    virtual void loadConfig_sensorSpecific(const mrpt::config::CConfigFileBase& configSource, const std::string& section);
    bool getObservation(mrpt::obs::CObservationRFID& obs);
    void closeReader();
};

Construction

CImpinjRFID()

Default constructor.

Methods

void connect()

Connect to the reader.

virtual void doProcess()

This method will be invoked at a minimum rate of “process_rate” (Hz)

Parameters:

This	method must throw an exception with a descriptive message if some critical error is found.

virtual void initialize()

This method can or cannot be implemented in the derived class, depending on the need for it.

Parameters:

This	method must throw an exception with a descriptive message if some critical error is found.

virtual void loadConfig_sensorSpecific(
    const mrpt::config::CConfigFileBase& configSource,
    const std::string& section
    )

Loads specific configuration for the device from a given source of configuration parameters, for example, an “.ini” file, loading from the section “[iniSection]” (see config::CConfigFileBase and derived classes)

Parameters:

This	method must throw an exception with a descriptive message if some critical parameter is missing or has an invalid value.

bool getObservation(mrpt::obs::CObservationRFID& obs)

Gets the information of the tags as a timestamped observation NOTE: Deprecated, use getObservations instead.

See CGenericSensor documentation. This function is kept for internal use of the module

Returns:

Returns true if the observation was correct, and false otherwise
