Node.js module for BlendMicro/BLENano with BLE

blendmicro-node's Issues

ble_set_name("BlendMicro") not works

#include <SPI.h>
#include <boards.h>
#include <RBL_nRF8001.h>

void setup()
{
  ble_set_name("MyBlendMicro"); // not work
  ble_begin();
}

write 20byte/1packet

BLE has limit its packet size 20byte. and 30msec interval required.
BlendMicro.write function should have a Queue and split 20byte to send message.

connect multiple BLE devices

var devices = ["BlendMicro", "Blend2"];

devices.map(function(device_name){
  return new BlendMicro(device_name);
}).forEach(function(bm){
  bm.on("data", function(data){
    console.log(data.toString() + " - from " + bm.name);
  });

  setInterval(function(){
    bm.write(new Date().toString());
  }, 1000);
});

each devices running samples/echo/echo.ino

this is ok

1. turn on device A and device B
2. run node.js
3. connect A and B

not work

1. turn on A
2. run node.js
3. connect A
4. turn on B
5. cannot connect B

cause

each BlendMicro instance has same noble object. So when A has connected, it calls noble.stopScanning() and disturb B.

calling removing ALL listeners when 1 close

  close: (callback) ->
    ble.noble.removeAllListeners()
    @peripheral.removeAllListeners()
    @peripheral.disconnect =>
      callback?()
      @emit 'close'
    @peripheral = null

add BLENano sample code

translate BlendMicro code for BLENano

• samples/echo/echo.ino
• samples/read_adc/read_adc.ino

read RSSI

BlendMicro = require 'blendmicro'
bm = new BlendMicro()

bm.on 'connect', ->
  setInterval ->
    console.log bm.rssi
  , 1000

Reopen connection on close

Hi! I'm using the "echo.js" example with a Blend Micro board.

Sometimes it happens to me that the connection close after 20-30 seconds. I have to stop the echo.js (via CTRL+C) and restart it via $node echo.js and it start again.

On Arduino side I have this message error:

data transmmit success!  Length: 15    Data Credit available: 1
Evt Disconnected/Advertising timed out
Advertising started

How to reconnect it automatically?

blendmicro terminal command

add blendmicro command

% blendmicro -list
% blendmicro -terminal (device_name)

reconnect to BLENano

cannot reconnect on close

bm.write not send data

Hello! I use the adc_read sketch and bm.write('Hello'). On blend micro i use Simple sketch from library rBL_nRF8001. Blend micro send data to node, node read data. bm.write not send data
