Node-RED nodes to talk to serial ports

• Jan 02, 2021 Below, we are sharing the links to USB drivers for most of the popular Android device manufacturers like Samsung, LG, Sony, Google, HTC, Motorola, Dell, etc. These USB drivers are safe to use as they are from their respective manufacturers. All the links are valid and official. We recommend you to download the latest USB drivers.
• If you own a ThinkPad laptop, go to Lenovo's support page, scroll to the bottom and download the appropriate drivers. These driver and firmware packages are designed to fix any USB-C problems.
• Updating Lenovo Drivers and Applications using Lenovo System Update.
• How to fix: Windows cannot initialize the device driver for this hardware, (Code 37). I am connecting my Samsung galaxy Android mobile to computer using USB.

Anything connected via USB is a device.Devices require a device driver, period. You might be able to get away with an existing driver built into Windows. This is how USB memory keys work for example - they present a generic device that looks like a removable disk, and Windows already includes the drivers for generic removable disks.

Node-RED nodes to talk tohardware 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

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 elsefailed, you should be able to use it. Occasionally some platforms will requireyou to install the full set of tools in order to compile the underlying package.

Usage

Drivers Code Red Usb Devices Wireless

Provides three nodes - one to receive messages, and one to send, and a request node which can send then wait for a response.

Input

Reads data from a local serial port.

Clicking on the search icon will attempt to autodetect serial ports attached tothe 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 streamof 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.
