Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

A Node-RED module based on noble for interaction with Bluetooth Low Energy (BLE) devices.

Installation

npm install node-red-contrib-noble-bluetooth

Prerequisite

Requires @abandonware/noble module for bluetooth communication

Quick Start

Create a BLE scanner node and hook its input up to an inject node. Send a message with topic "start" to start scanning for devices. By befault it will search for any device. Can be configured to only search for devices publishing certaing services by providing an array of UUID's.

Connect the output to a BLE device node to connect to the found device. This will establish a connection to the device and discover all published services and characteristics.

Use a BLE in node to read from the device or a BLE out note to write to it.

More details about parameters and usage in each node's info panel.

Examples

The following show some simple examples of how to use the nodes. They are both available from the Import menu in the Node RED editor.

Scan for Devices

Shows the different ways to scan for devices, including continuous mode or for a limited time.

Heart Rate Sensor
