TSLAsciiCommander provides methods to communicate with TSL devices that use the TSL ASCII 2.0 Protocol Instances of this class support: •communication with any TSL Reader via an IAsciiSerialTransport •execution of an IAsciiCommand either synchronously or asynchronously •management of the responder chain for data received from the TSL device

Constructors

AsciiCommander()

Initializes a new instance of the AsciiCommander class

public AsciiCommander()

Properties

IsConnected

Gets a value indicating whether a reader is connected

public bool IsConnected { get; }

Property Value

bool

Transport

Gets or sets the transport used by this AsciiCommander

public IAsciiSerialTransport Transport { get; set; }

Property Value

IAsciiSerialTransport

Methods

CanExecuteCommand()

Returns a value indicating whether a command can be executed

public override bool CanExecuteCommand()

Returns

bool

True if ExecuteCommand can be called

Remarks

This should be false when the reader is not connected or currently executing a command

Connect(IAsciiSerialTransport)

Connect the AsciiCommander to the given reader

public bool Connect(IAsciiSerialTransport transport)

Parameters

transport IAsciiSerialTransport

The UHF Reader that supports the TSL ASCII 2.0 protocol

Returns

bool

True if successfully connected

Remarks

This will Disconnect() any connected Transport before assigning it to transport

Disconnect()

Disconnects from the current device by disposing and setting the Transport property to null (Nothing in Visual Basic)

public void Disconnect()

Dispose(bool)

Disposes an instance of the AsciiCommander class

protected override void Dispose(bool disposing)

Parameters

disposing bool

True to dispose managed as well as unmanaged resources

PermanentlyDisconnect()

Sends the signal to the accessory to permanently disconnect

[Obsolete("Execute a SleepCommand instead")]
public void PermanentlyDisconnect()

Remarks

Once issued this will require reconnecting to the reader to use the accessory again. This may require switching to the iOS Settings App This is a convenience method and is equivalent to sending a TSLSleepCommand to the reader

Send(string)

Send the given string as a CrLf terminated string, to the reader. This method waits until the command has been successfully sent

public override void Send(string line)

Parameters

line string

line The ASCII string to send to the device

Exceptions

InvalidOperationException

if no device is connected
