Basic Functions¶

Class BrickletRemoteSwitch(ByVal uid As String, ByVal ipcon As IPConnection)¶

Creates an object with the unique device ID uid:

Dim remoteSwitch As New BrickletRemoteSwitch("YOUR_DEVICE_UID", ipcon)

This object can then be used after the IP Connection is connected.

Sub BrickletRemoteSwitch.SwitchSocket(ByVal houseCode As Byte, ByVal receiverCode As Byte, ByVal switchTo As Byte)¶

Parameters:	houseCode – Type: Byte, Range: [0 to 31] receiverCode – Type: Byte, Range: [0 to 31] switchTo – Type: Byte, Range: See constants

This function is deprecated, use SwitchSocketA() instead.

The following constants are available for this function:

For switchTo:

• BrickletRemoteSwitch.SWITCH_TO_OFF = 0
• BrickletRemoteSwitch.SWITCH_TO_ON = 1

Function BrickletRemoteSwitch.GetSwitchingState() As Byte¶

Returns:	state – Type: Byte, Range: See constants

Returns the current switching state. If the current state is busy, the Bricklet is currently sending a code to switch a socket. It will not accept any requests to switch sockets until the state changes to ready.

How long the switching takes is dependent on the number of repeats, see SetRepeats().

The following constants are available for this function:

For state:

• BrickletRemoteSwitch.SWITCHING_STATE_READY = 0
• BrickletRemoteSwitch.SWITCHING_STATE_BUSY = 1

New in version 2.0.1 (Plugin).

Advanced Functions¶

Sub BrickletRemoteSwitch.SetRepeats(ByVal repeats As Byte)¶

Parameters:	repeats – Type: Byte, Range: [0 to 255], Default: 5

Sets the number of times the code is sent when one of the switch socket functions is called. The repeats basically correspond to the amount of time that a button of the remote is pressed.

Some dimmers are controlled by the length of a button pressed, this can be simulated by increasing the repeats.

Function BrickletRemoteSwitch.GetRepeats() As Byte¶

Returns:	repeats – Type: Byte, Range: [0 to 255], Default: 5

Returns the number of repeats as set by SetRepeats().

Sub BrickletRemoteSwitch.GetIdentity(ByRef uid As String, ByRef connectedUid As String, ByRef position As Char, ByRef hardwareVersion() As Byte, ByRef firmwareVersion() As Byte, ByRef deviceIdentifier As Integer)¶

Output Parameters:

uid – Type: String, Length: up to 8 connectedUid – Type: String, Length: up to 8 position – Type: Char, Range: ["a"C to "h"C, "z"C] hardwareVersion – Type: Byte Array, Length: 3 0: major – Type: Byte, Range: [0 to 255] 1: minor – Type: Byte, Range: [0 to 255] 2: revision – Type: Byte, Range: [0 to 255] firmwareVersion – Type: Byte Array, Length: 3 0: major – Type: Byte, Range: [0 to 255] 1: minor – Type: Byte, Range: [0 to 255] 2: revision – Type: Byte, Range: [0 to 255] deviceIdentifier – Type: Integer, Range: [0 to 216 - 1]

Returns the UID, the UID where the Bricklet is connected to, the position, the hardware and firmware version as well as the device identifier.

The position can be 'a', 'b', 'c', 'd', 'e', 'f', 'g' or 'h' (Bricklet Port). A Bricklet connected to an Isolator Bricklet is always at position 'z'.

The device identifier numbers can be found here. There is also a constant for the device identifier of this Bricklet.

Callbacks¶

Callbacks can be registered to receive time critical or recurring data from the device. The registration is done by assigning a procedure to an callback property of the device object:

Sub MyCallback(ByVal sender As BrickletRemoteSwitch, ByVal value As Short)
    Console.WriteLine("Value: {0}", value)
End Sub

AddHandler remoteSwitch.ExampleCallback, AddressOf MyCallback

The available callback property and their type of parameters are described below.

Event BrickletRemoteSwitch.SwitchingDoneCallback(ByVal sender As BrickletRemoteSwitch)¶

Callback Parameters:	sender – Type: BrickletRemoteSwitch

This callback is triggered whenever the switching state changes from busy to ready, see GetSwitchingState().

Virtual Functions¶

Virtual functions don't communicate with the device itself, but operate only on the API bindings device object. They can be called without the corresponding IP Connection object being connected.

Function BrickletRemoteSwitch.GetAPIVersion() As Byte()¶

Output Parameters:	apiVersion – Type: Byte Array, Length: 3 0: major – Type: Byte, Range: [0 to 255] 1: minor – Type: Byte, Range: [0 to 255] 2: revision – Type: Byte, Range: [0 to 255]

Returns the version of the API definition implemented by this API bindings. This is neither the release version of this API bindings nor does it tell you anything about the represented Brick or Bricklet.

Function BrickletRemoteSwitch.GetResponseExpected(ByVal functionId As Byte) As Boolean¶

Parameters:	functionId – Type: Byte, Range: See constants
Returns:	responseExpected – Type: Boolean

Returns the response expected flag for the function specified by the function ID parameter. It is true if the function is expected to send a response, false otherwise.

For getter functions this is enabled by default and cannot be disabled, because those functions will always send a response. For callback configuration functions it is enabled by default too, but can be disabled by SetResponseExpected(). For setter functions it is disabled by default and can be enabled.

Enabling the response expected flag for a setter function allows to detect timeouts and other error conditions calls of this setter as well. The device will then send a response for this purpose. If this flag is disabled for a setter function then no response is sent and errors are silently ignored, because they cannot be detected.

The following constants are available for this function:

For functionId:

• BrickletRemoteSwitch.FUNCTION_SWITCH_SOCKET = 1
• BrickletRemoteSwitch.FUNCTION_SET_REPEATS = 4
• BrickletRemoteSwitch.FUNCTION_SWITCH_SOCKET_A = 6
• BrickletRemoteSwitch.FUNCTION_SWITCH_SOCKET_B = 7
• BrickletRemoteSwitch.FUNCTION_DIM_SOCKET_B = 8
• BrickletRemoteSwitch.FUNCTION_SWITCH_SOCKET_C = 9

Sub BrickletRemoteSwitch.SetResponseExpected(ByVal functionId As Byte, ByVal responseExpected As Boolean)¶

Parameters:	functionId – Type: Byte, Range: See constants responseExpected – Type: Boolean

Changes the response expected flag of the function specified by the function ID parameter. This flag can only be changed for setter (default value: false) and callback configuration functions (default value: true). For getter functions it is always enabled.

Enabling the response expected flag for a setter function allows to detect timeouts and other error conditions calls of this setter as well. The device will then send a response for this purpose. If this flag is disabled for a setter function then no response is sent and errors are silently ignored, because they cannot be detected.

The following constants are available for this function:

For functionId:

• BrickletRemoteSwitch.FUNCTION_SWITCH_SOCKET = 1
• BrickletRemoteSwitch.FUNCTION_SET_REPEATS = 4
• BrickletRemoteSwitch.FUNCTION_SWITCH_SOCKET_A = 6
• BrickletRemoteSwitch.FUNCTION_SWITCH_SOCKET_B = 7
• BrickletRemoteSwitch.FUNCTION_DIM_SOCKET_B = 8
• BrickletRemoteSwitch.FUNCTION_SWITCH_SOCKET_C = 9

Sub BrickletRemoteSwitch.SetResponseExpectedAll(ByVal responseExpected As Boolean)¶

Parameters:	responseExpected – Type: Boolean

Changes the response expected flag for all setter and callback configuration functions of this device at once.

Constants¶

Const BrickletRemoteSwitch.DEVICE_IDENTIFIER¶

This constant is used to identify a Remote Switch Bricklet.

The GetIdentity() function and the IPConnection.EnumerateCallback callback of the IP Connection have a deviceIdentifier parameter to specify the Brick's or Bricklet's type.

Const BrickletRemoteSwitch.DEVICE_DISPLAY_NAME¶

This constant represents the human readable name of a Remote Switch Bricklet.
