API

Since Visual Basic .NET does not support multiple return values directly, we use the ByRef keyword to return multiple values from a function.

All functions and procedures listed below are thread-safe.

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 (see examples above).

Sub BrickletRemoteSwitch.SwitchSocket(ByVal houseCode As Byte, ByVal receiverCode As Byte, ByVal switchTo As Byte)
Parameters:
  • houseCode – Type: Byte, Range: [0 to 255]
  • receiverCode – Type: Byte, Range: [0 to 255]
  • 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 calls of SwitchSocket() 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
Sub BrickletRemoteSwitch.SwitchSocketA(ByVal houseCode As Byte, ByVal receiverCode As Byte, ByVal switchTo As Byte)
Parameters:
  • houseCode – Type: Byte, Range: [0 to 255]
  • receiverCode – Type: Byte, Range: [0 to 255]
  • switchTo – Type: Byte, Range: See constants

To switch a type A socket you have to give the house code, receiver code and the state (on or off) you want to switch to.

The house code and receiver code have a range of 0 to 31 (5bit).

A detailed description on how you can figure out the house and receiver code can be found here.

The following constants are available for this function:

For switchTo:

  • BrickletRemoteSwitch.SWITCH_TO_OFF = 0

Parameters:
  • address – Type: Long, Range: [0 to 232 - 1]
  • unit – Type: Byte, Range: [0 to 255]
  • switchTo – Type: Byte, Range: See constants

To switch a type B socket you have to give the address, unit and the state (on or off) you want to switch to.

The address has a range of 0 to 67108863 (26bit) and the unit has a range of 0 to 15 (4bit). To switch all devices with the same address use 255 for the unit.

A detailed description on how you can teach a socket the address and unit can be found here.

Parameters:
  • systemCode – Type: Char
  • deviceCode – Type: Byte, Range: [0 to 255]
  • switchTo – Type: Byte, Range: See constants

To switch a type C socket you have to give the system code, device code and the state (on or off) you want to switch to.

The system code has a range of 'A' to 'P' (4bit) and the device code has a range of 1 to 16 (4bit).

A detailed description on how you can figure out the system and device code can be found here.

The following constants are available for this function:

For switchTo:

  • BrickletRemoteSwitch.SWITCH_TO_OFF = 0
  • BrickletRemoteSwitch.SWITCH_TO_ON = 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]

Sets the number of times the code is send when of the SwitchSocket() 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.

The default value is 5.

Function BrickletRemoteSwitch.GetRepeats() As Byte
Returns:
  • repeats – Type: Byte, Range: [0 to 255]

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

Function BrickletRemoteSwitch.GetAPIVersion() As Byte()
Returns:
  • apiVersion – Type: Byte Array, Length: 3, Range: [0 to 255]

Returns the version of the API definition (major, minor, revision) 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 send 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 send 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.

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
  • hardwareVersion – Type: Byte Array, Length: 3, Range: [0 to 255]
  • firmwareVersion – Type: Byte Array, Length: 3, 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' or 'd'.

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.

Note

Using callbacks for recurring events is always preferred compared to using getters. It will use less USB bandwidth and the latency will be a lot better, since there is no round trip time.

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().

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.
