BlendMicro not read data from node.js

[qazaqstem]

On blend micro i use SimpleChat.ino. On RPI3 i use https://www.npmjs.com/package/blendmicro this library. Blend micro send data to the node, and rpi3 read this data. If i send data to from blendmicro to the node, node not read. On node i use this code

var BlendMicro = require("#{__dirname}/../../");
// var BlendMicro = require("blendmicro");

var bm = new BlendMicro(process.argv[2]);

bm.on("open", function(){
  console.log("open");
});

bm.on("data", function(data){
  console.log(data.toString());
});

process.stdin.setEncoding("utf8");

// write data from STDIN
process.stdin.on("readable", function(){
  var chunk = process.stdin.read();
  if(chunk == null) return;
  chunk = chunk.toString().replace(/[\r\n]/g, '');
  bm.write(chunk);
});
