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 🙏

Usage

  • Before starting any advertisement, you need to set the company ID. you need to register your ble company identifier on https://www.bluetooth.com/ the company id is 2 bytes. for demo purposes we will use 00E0
import BleAdvertise from "react-native-ble-advertise";
// ...
BleAdvertise.setCompanyId(0x00E0);
  • To start advertising, you will need to prepare a 16 byte UUID, 2 byte Major, and 2 byte Minor
import BleAdvertise from "react-native-ble-advertise";
// ...
const uuid = "44C13E43-097A-9C9F-537F-5666A6840C08";
const major = parseInt("CD00", 16);
const minor = parseInt("0003", 16);

BLEAdvertise.broadcast(uuid, major, minor)
                .then(success => {
                    console.log('broadcast started');
                }).catch(error => { 
		    console.log('broadcast failed with: ' + error);
		});

the advertising data as per example will be broadcasted in the following order

E000021544C13E43097A9C9F537F5666A6840C08CD000003

companyID (E000), iBeacon identifier(0215), UUID(44C13E43097A9C9F537F5666A6840C08), Major(CD00), Minor(0003)

  • To stop advertising, you need to call the stopBroadcast method
import BleAdvertise from "react-native-ble-advertise";
// ...
BLEAdvertise.stopBroadcast()
                .then(success => {
                    console.log('broadcast stopped');
                }).catch(error => { 
		    console.log('broadcast failed to stop with: ' + error);
		});
