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 🙏

abeeway-driver

This is an open driver software for Abeeway Micro Tracker and Industrial Tracker devices (with firmware v1.8). The driver can be used to decode LoRaWAN uplink message payload and to encode device configuration commands so that they can be sent as LoRaWAN downlink payload. An online application demonstrating all features of this driver is aveilable here: >>

For more details on Abeeway tracker devices please visit the Abeeway website.

The code was written based on the reference guides that are available in the /docs directory of this repository.

Abeeway Application Protocol Data Unit (PDU) Objects

This driver is introdicing the concept of Protocol Data Unit (PDU) objects that you can create from

  • number,
  • buffer,
  • hex string representation of the buffer,
  • object,
  • JSON representation of the object

by using the PDU's constructor method.

If you have an already created PDU object, you can convert it to

  • number (with the .toValue() method of the object),
  • buffer (with the .toBuffer() method of the object),
  • hex string representation of the buffer (with the .toHesString() method of the object),
  • object (with the .toComponents() method of the object),
  • JSON representation of the object (with the .toJSON() method of the object)

There are 3 types of PDUs

  • UPDU , represents an uplink message
  • DPDU , represents a downlink message
  • CPDU , Component PDU that represents a component of an UPDU or DPDU

In order to allow programmers to easily recognize the type of PDUs the class names of PDUs always have one of the following prefixes: UPDU_, DPDU_ or CPDU_

Beyond PDUs, the driver defines a long list of constants. Please note that all enum constants are referred with prefix E_.

Install abeeway-driver

npm install abeeway-driver --save

Use abeeway-driver to decode an uplink message

const { createUPDU } = require('abeeway-driver');

const uplinkPayloadHex = '0781f98350020e000000030f00000001';
let pdu = createUPDU(uplinkPayloadHex);
console.log( 'The type of this PDU is: ' + pdu.header.type );
console.log( pdu.toJSON() );

Use abeeway-driver to encode a device command to send in a downlink message

const {
    DPDU_SetParam, 
    CPDU_DlHeaderShort, E_DPDUType,
    CPDU_Parameter, E_ParameterId
} = require('abeeway-driver');

// Create a new "Set Parameter Value" PDU object from its components
let pdu = new DPDU_SetParam({
    header: new CPDU_DlHeaderShort({
        type: E_DPDUType.SET_PARAM,
        ackToken: 0x5,
        optData: 0x0,
    }),
    params: [
        // Up to 5 parameters can be listed here
        new CPDU_Parameter({
            id: E_ParameterId.UL_PERIOD,
            value: 60,
        }),
        new CPDU_Parameter({
            id: E_ParameterId.LORA_PERIOD,
            value: 300,
        }),
    ]
});
console.log(pdu.toHexString());
