Basic Functions¶

BrickletRemoteSwitch::new(uid, ipcon) → remote_switch¶

Parameters:	uid – Type: str ipcon – Type: IPConnection
Returns:	remote_switch – Type: BrickletRemoteSwitch

Creates an object with the unique device ID uid:

remote_switch = BrickletRemoteSwitch.new 'YOUR_DEVICE_UID', ipcon

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

BrickletRemoteSwitch#switch_socket(house_code, receiver_code, switch_to) → nil¶

Parameters:	house_code – Type: int, Range: [0 to 31] receiver_code – Type: int, Range: [0 to 31] switch_to – Type: int, Range: See constants

This function is deprecated, use #switch_socket_a instead.

The following constants are available for this function:

For switch_to:

Advanced Functions¶

BrickletRemoteSwitch#set_repeats(repeats) → nil¶

Parameters:	repeats – Type: int, 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.

BrickletRemoteSwitch#get_repeats → int¶

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

Returns the number of repeats as set by #set_repeats.

BrickletRemoteSwitch#get_identity → [str, str, chr, [int, ...], [int, ...], int]¶

Return Array:

0: uid – Type: str, Length: up to 8 1: connected_uid – Type: str, Length: up to 8 2: position – Type: chr, Range: ['a' to 'h', 'z'] 3: hardware_version – Type: [int, ...], Length: 3 0: major – Type: int, Range: [0 to 255] 1: minor – Type: int, Range: [0 to 255] 2: revision – Type: int, Range: [0 to 255] 4: firmware_version – Type: [int, ...], Length: 3 0: major – Type: int, Range: [0 to 255] 1: minor – Type: int, Range: [0 to 255] 2: revision – Type: int, Range: [0 to 255] 5: device_identifier – Type: int, 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.

Callback Configuration Functions¶

BrickletRemoteSwitch#register_callback(callback_id) { |param [, ...]| block } → nil¶

Parameters:	callback_id – Type: int

Registers the given block with the given callback_id.

The available callback IDs with corresponding function signatures are listed below.

Callbacks¶

Callbacks can be registered to receive time critical or recurring data from the device. The registration is done with the #register_callback function of the device object. The first parameter is the callback ID and the second parameter is a block:

remote_switch.register_callback BrickletRemoteSwitch::CALLBACK_EXAMPLE, do |param|
  puts "#{param}"
end

The available constants with inherent number and type of parameters are described below.

BrickletRemoteSwitch::CALLBACK_SWITCHING_DONE¶

Callback Parameters:	no parameters

This callback is triggered whenever the switching state changes from busy to ready, see #get_switching_state.

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.

BrickletRemoteSwitch#get_api_version → [int, ...]¶

Return Array:	0: api_version – Type: [int, ...], Length: 3 0: major – Type: int, Range: [0 to 255] 1: minor – Type: int, Range: [0 to 255] 2: revision – Type: int, 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.

BrickletRemoteSwitch#get_response_expected(function_id) → bool¶

Parameters:	function_id – Type: int, Range: See constants
Returns:	response_expected – Type: bool

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 #set_response_expected. 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 function_id:

• 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

BrickletRemoteSwitch#set_response_expected(function_id, response_expected) → nil¶

Parameters:	function_id – Type: int, Range: See constants response_expected – Type: bool

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 function_id:

• 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

BrickletRemoteSwitch#set_response_expected_all(response_expected) → nil¶

Parameters:	response_expected – Type: bool

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

Constants¶

BrickletRemoteSwitch::DEVICE_IDENTIFIER¶

This constant is used to identify a Remote Switch Bricklet.

The #get_identity() function and the IPConnection::CALLBACK_ENUMERATE callback of the IP Connection have a device_identifier parameter to specify the Brick's or Bricklet's type.

BrickletRemoteSwitch::DEVICE_DISPLAY_NAME¶

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