node-red-node-serialport
========================
<a href="http://nodered.org" target="noderedinfo">Node-RED</a> nodes to talk to
hardware serial ports.
## Install
To install the stable version use the `Menu - Manage palette - Install` option and search for node-red-node-serialport, or run the following command in your Node-RED user directory, typically `~/.node-red`
npm i node-red-node-serialport
During install there may be multiple messages about optional compilation.
These may look like failures... as they report as failure to compile errors -
but often are warnings and the node will continue to install and, assuming nothing else
failed, you should be able to use it. Occasionally some platforms *will* require
you to install the full set of tools in order to compile the underlying package.
## Usage
Provides four nodes - one to receive messages, and one to send, a request node which can send then wait for a response, and a control node that allows dynamic control of the ports in use.
### Input
Reads data from a local serial port.
Clicking on the search icon will attempt to autodetect serial ports attached to
the device, however you many need to manually specify it. COM1, /dev/ttyUSB0, etc
It can either
- wait for a "split" character (default \n). Also accepts hex notation (0x0a).
- wait for a timeout in milliseconds from the first character received
- wait to fill a fixed sized buffer
It then outputs `msg.payload` as either a UTF8 ascii string or a binary Buffer object.
If no split character is specified, or a timeout or buffer size of 0, then a stream
of single characters is sent - again either as ascii chars or size 1 binary buffers.
### Output
Provides a connection to an outbound serial port.
Only the `msg.payload` is sent.
Optionally the character used to split the input can be appended to every message sent out to the serial port.
### Request
Provides a connection to a request/response serial port.
This node behaves as a tightly coupled combination of serial in and serial out nodes, with which it shares the configuration.
Send the request message in `msg.payload` as you would do with a serial out node. The message will be forwarded to the serial port following a strict FIFO (First In, First Out) queue, waiting for a single response before transmitting the next request. Once a response is received (with the same logic of a serial in node), or after a timeout occurs, a message is produced on the output, with msg.payload containing the received response (or missing in case if timeout), msg.status containing relevant info, and all other fields preserved.
For consistency with the serial in node, msg.port is also set to the name of the port selected.
### Control
When the node-red starts, the flow(program) picks up the pre-programmed serial port, open it, and starts the communication. But there are some cases the port needs to switch to a different port, stop, and start again. For example, in order to upload a new binary for Arduino, the serial port needs to be stopped relased from the nodered, and start it again after uploading. Or when the FTDI device re-connects after disconnecting for any reason, it may be possible that the port number changes, and the end user of the flow can't change the port.
This node provides the ability to:
1. change the serial port and its configuration on the run time programatically.
2. stop the communication and release the serial port.
3. reopen the port and restart the communications.
In order to control the communication, send a **msg.payload** to the control node.
{
"serialport": "/dev/ttyUSB0",
"serialbaud": 115200,
"databits": 8,
"parity": "none",
"stopbits": 1,
"enabled": true
}
changes the serial port and the configuration on the fly.
The following optional parameters will change the configuration only if they are present.
Any combination of them can be passed to change/control the serial communication
- serialport
- serialbaud
- databits
- parity
- stopbits
- dtr
- rts
- cts
- dsr
- enabled
If the `enabled` property is not present, it will default to `true`.
`{"enabled":true}` or `{"enabled":false}` will start or stop the communication.
If `enabled` is passed along with other parameters, the configuration will be changed and the port will be either started or remain stopped, ready to be started later depending on its value.
Any input message will cause the node to output the current port configuration.

Die Nachrichten werden an die serielle Schnittstelle nach dem strikten FIFO-Prinzip (First In, First Out) weitergereicht,
d.h. nach jeder gesendeten Anfrage wird auf die Antwort der Gegenstelle gewartet,
bevor mit der nächsten Anfrage fortgefahren wird.
Wenn die Antwort empfangen wurde (mit der selben Logik eines <span style="background-color:Gainsboro">serial in</span>-Nodes)
oder wenn ein Zeitablauf aufgetreten ist, wird eine Nachricht ausgegeben (siehe Ausgangsdaten unten)
mit <code>msg.payload</code>, die empfangene Antwort enthaltend (oder fehlend im Falle eines Zeitablaufs),

<li><code>msg.waitfor</code> muss ein Einzelzeichen, ein Escape-Code oder eine Hex-Code sein.

<p>Wenn die <code>enabled</code> Eigenschaft nicht vorhanden ist, wird sie standardmäßig auf <code>true</code> gesetzt.</p>

<code>{"enabled":true}</code> oder <code>{"enabled":false}</code> startet oder stopt die Kommunikation.</p>
<p>Wenn <code>enabled</code> zusammen mit anderen Parametern übergeben wird, wird die Konfiguration geändert und der Port wird entweder gestartet oder bleibt gestoppt, sodass er abhängig von seinem Wert später gestartet werden kann.</p>

<p>Jede Eingabenachricht führt dazu, dass der Knoten die aktuelle Portkonfiguration in <code>msg.payload</code> ausgibt.</p>

<script type="text/html" data-help-name="serial request">
<p>Provides a connection to a request/response serial port.</p>
<p>This node behaves as a tightly coupled combination of <code>serial in</code> and <code>serial out</code> nodes,
with which it shares the configuration.</p>
<p>Send the request message in <code>msg.payload</code> as you would do with a <code>serial out</code> node.
The message will be forwarded to the serial port following a strict FIFO (First In, First Out) queue,
waiting for a single response before transmitting the next request.
Once a response is received (with the same logic of a <code>serial in</code> node), or after a timeout occurs,
a message is sent to the output (see Outputs below),
with <code>msg.payload</code> containing the received response (or missing in case if timeout) and
all other properties are preserved.</p>
<p>For consistency with the <code>serial in</code> node, <code>msg.port</code> is set to the name of the port selected.</p>
<h3>Inputs</h3>
<ul>
<li><code>msg.timeout</code> is the timeout (in ms) after which the incoming message is propagated
to the output with <code>msg.status</code> set to <code>"ERR_TIMEOUT"</code> and missing payload.
If not present, the default value is 10000 (10s).</li>
<li><code>msg.count</code> if set this will override the configured number of characters
as long as it is less than the number configured.</li>
<li><code>msg.waitfor</code> must be a single character, escape code, or hex code.
If set, the node will wait until it matches that character in the stream and then start the output.</li>
<li>Optionally the baudrate can be changed using <code>msg.baudrate</code></li>
</ul>
<h3>Outputs</h3>
<ul>
<li><code>msg.payload</code> is the response. If no response occured, this property is removed.</li>
<li><code>msg.status</code> is <code>"OK"</code> in case a response is received,
or <code>"ERR_TIMEOUT"</code> if a timeout occurs.</li>
<li>Any other property coming from the input will be preserved.</li>
</ul>

<script type="text/html" data-help-name="serial-port">
<p>Configuration options for a local serial port.</p>
<p>The search button should return a list of available serial ports to choose from,
or you can type in the location if known.</p>
<p>The DTR, RTS, CTS and DSR switches can be used to permanently pull the corresponding flow control pin high or low,
e.g. in order to power devices via those pins.</p>
<p>The node can optionally wait until it matches a pre-defined character.</p>
<p>The serial data reception can either
<ul>
<li>wait for a "split" character (default \n). Also accepts escaped shortcut (e.g. \n) or hex notation (0x0d).</li>
<li>wait for a timeout in milliseconds from the first character received.</li>
<li>wait for a silence time in milliseconds after the last character received.</li>
<li>wait to fill a fixed sized buffer.</li>

<li>reopen the port and restart the communications.</li>
<li>change the serial port and the configuration dynamically.</li>
<li>query the serial port configuration.</li>

<code>{"enabled":true}</code> or <code>{"enabled":false}</code> will start or stop the communication.</p>
<p>If <code>enabled</code> is passed along with other parameters, the configuration will be changed and the
