Generally, every function of the JavaScript bindings can take two optional
parameters, returnCallback
and errorCallback
. These are two user
defined callback functions. The returnCallback
function is called with the
results as arguments, if the function returns its results asynchronously. The
errorCallback
is called with an error code in case of an error. The error
code can be one of the following values:
The namespace for the JavaScript bindings is Tinkerforge.*
.
BrickletRemoteSwitchV2

The temperature is only proportional to the real temperature and it has bad accuracy. Practically it is only useful as an indicator for temperature changes.
BrickletRemoteSwitchV2.
reset
([returnCallback][, errorCallback])¶Callback Parameters: |
|
---|---|
Returns: |
|
Calling this function will reset the Bricklet. All configurations will be lost.
After a reset you have to create new device objects, calling functions on the existing ones will result in undefined behavior!
BrickletRemoteSwitchV2.
getIdentity
([returnCallback][, errorCallback])¶Callback Parameters: |
|
---|---|
Returns: |
|
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 can be registered to receive
time critical or recurring data from the device. The registration is done
with the on()
function of
the device object. The first parameter is the callback ID and the second
parameter the callback function:
remoteSwitchV2.on(BrickletRemoteSwitchV2.CALLBACK_EXAMPLE,
function (param) {
console.log(param);
}
);
The available constants with inherent number and 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.
BrickletRemoteSwitchV2.
CALLBACK_SWITCHING_DONE

to be seen before the callback is triggered for the first time.
The following constants are available for this function:
For switch_to:
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.
BrickletRemoteSwitchV2.
getAPIVersion
()¶Returns: |
|
---|
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.
BrickletRemoteSwitchV2.
getResponseExpected
(functionId[, errorCallback])¶Parameters: |
|
---|---|
Returns: |
|
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 function_id:
BrickletRemoteSwitchV2.
setResponseExpected
(functionId, responseExpected[, errorCallback])¶Parameters: |
|
---|---|
Returns: |
|
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:
BrickletRemoteSwitchV2.
setResponseExpectedAll
(responseExpected)¶Parameters: |
|
---|---|
Returns: |
|
Changes the response expected flag for all setter and callback configuration functions of this device at once.
Internal functions are used for maintenance tasks such as flashing a new firmware of changing the UID of a Bricklet. These task should be performed using Brick Viewer instead of using the internal functions directly.
BrickletRemoteSwitchV2.
setBootloaderMode
(mode[, returnCallback][, errorCallback])¶Parameters: |
|
---|---|
Callback Parameters: |
|
Returns: |
|
Sets the bootloader mode and returns the status after the requested mode change was instigated.
You can change from bootloader mode to firmware mode and vice versa. A change from bootloader mode to firmware mode will only take place if the entry function, device identifier and CRC are present and correct.
This function is used by Brick Viewer during flashing. It should not be necessary to call it in a normal user program.
The following constants are available for this function:
For mode:
For status:
BrickletRemoteSwitchV2.
getBootloaderMode
([returnCallback][, errorCallback])¶Callback Parameters: |
