nesslab-reader-api
Advanced tools
Node module to rfid reader nesslab.
Módulo desenvolvido para facilitar a comunicação do node.js com o leitor rfid da NESSLAB, que é um dos mais acessíveis no mercado. Foi testado apenas no modelo NL_RF1000.
npm install nesslab-reader-api
require
como no exemplo a seguir
var reader = require('nesslab-reader-api');
//Connecting reader.connect('192.168.0.100',5578);
//On connect reader.on('connect', function(res){ console.log(res); //Starting reading reader.init(); });
//On tag reader.on('tag',function(res){ //Nmber of tag console.log(res.tag); //Antenna console.log(res.antenna); //Antena+tag console.log(res.tagId); });
reader.disableAntenna(1);
reader.setPowerAntenna(1,200);
stateport1, stateport2, stateport3 e stateport4
que veremos mais a frente.
antennapower
que veremos mais a baixo.
connect
reader.on('tag',function(res){
console.log(res.tag);
});
reader.on('tag',function(res){
console.log(res.tagId); //Mostra 4T3000000000000000000000000295
console.log(res.tag); //Mostra 3000000000000000000000000295
console.log(res.antenna); //Mostra 4
});
var reader = require('nesslab-reader-api');
//Connecting reader.connect('192.168.0.100',5578);
//On connect reader.on('connect', function(res){ console.log(res); //Connected });
var reader = require('nesslab-reader-api');
//Connecting reader.connect('192.168.0.100',5578);
//On disconnect reader.on('disconnected', function(res){ console.log(res); //Connection error });
getPower()
é chamado. Veja um exemplo
var reader = require('nesslab-reader-api');
//Connecting
reader.connect('192.168.0.100',5578);
reader.getPower();
reader.on('antennapower', function(power){
console.log(power);
});
getAntennaState
for chamado os eventos referente ao estado de cada antena será chamado, retornando verdadeiro para as ativas e falsos para as inativas, veja a baixo:
var reader = require('nesslab-reader-api');
//Connecting reader.connect('192.168.0.100',5578);
//Getting states reader.getAntennaState();
//Antenna 1 reader.on('stateport1', function(state){ console.log(state); });
//Antenna 2 reader.on('stateport1', function(state){ console.log(state); });
//Antenna 3 reader.on('stateport1', function(state){ console.log(state); });
//Antenna 4 reader.on('stateport1', function(state){ console.log(state); });
