NMEA-BUFFER

To send and parse nmea message socket

NmeaBuffer.getMessageBuffer

params header : string

    send 5 chars string indicate method name ou header

message : string

    string message

return uint 8 bits array to send message

const NmeaBuffer = require('nmea-buffer') ;
const client = new net.Socket();

let ip = '168.0.0.1' ;
client.connect(8000, ip, function() {
    console.log('Connected');
    const array2send = NmeaBuffer.getMessageBuffer( "START", "ITS JUST A TEST" ) ;
    //out is: [int8, int8, int8, int8 ... ]
    client.write(array2send) ;
});

NmeaBuffer.string2Buffer

params header : string

    send 5 chars string indicate method name ou header

message : string

    string message

return Buffer Object

const NmeaBuffer = require('nmea-buffer') ;

let buffer = NmeaBuffer.string2Buffer( "12345", "test,4,5" ) ;
//out is: Buffer object

NmeaBuffer.bufferToUint8

params buffer : Buffer Object

return uint 8 bits array to send message

const Buffer        = require('buffer').Buffer ;
const NmeaBuffer = require('nmea-buffer') ;

let uitArray = NmeaBuffer.bufferToUint8( new Buffer() ) ;
//out is: uint 8 bits array to send message

NmeaBuffer.parse

params data : string

return object: { header:string, message:string }

const NmeaBuffer = require('nmea-buffer') ;
const client = new net.Socket();

let ip = '168.0.0.1' ;
client.connect(8000, ip, function() {}) ;

client.on('data', function(data) {
    const ob = NmeaBuffer.parse( data ) ;
    //out object { header, message }
}
