Blend Micro Arduino Timeout problem

Question

This is the second part of the problem firstly exposed in this question.

I have the problem that, with a Blend Micro Arduino board from Red Bear Lab after a while (randomly changes from 20 sec to 6 minutes more or less) the connection of the arduino with my computer or my android device close due to a timeout. The problem occurs with nothing attached to the board (no sensors, no I2C, no led, nothing, only the board).

In the arduino IDE serial monitor I have this error:

Evt Disconnected/Advertising timed out
Advertising started

I'm using the arduino to send data, and a Mac Book Pro with Mac OS/X 10.8.5, or a Motorola Moto-G Android 4.4.4 to receive data.

In the mac I'm using the echo.js example of blend micro module of node.js language.

In the Android I'm using the official BLE Controller from ReadBearLab.com, SimpleChat example.

In each cases (both with mac book pro and android) when the timeout occurs, if I close and restart the application, connection restart for few time (before the next timeout). During some tests, the longest duration of a stable connection was 10 minutes.

In Arduino side I'm using a HelloWorld.ino example:

//"services.h/spi.h/boards.h" is needed in every new project
#include <SPI.h>
#include <boards.h>
#include <RBL_nRF8001.h>

void setup()
{
  //ble_begin();
  ble_begin_debug();
  
  Serial.begin(57600);
}

unsigned char buf[16] = {0};
unsigned char len = 0;

void loop()
{
  if ( ble_connected() )
  {
    ble_write('H');
    ble_write('e');
    ble_write('l');
    ble_write('l');
    ble_write('o');
    ble_write(' ');
    ble_write('W');
    ble_write('o');
    ble_write('r');
    ble_write('l');
    ble_write('d');
    ble_write('!');
  }

  ble_do_events();
   
  delay(100);  
}

In this example I have added a new method for debug (thanks to Star Destroyer advice to have more information) copying the ble_begin() method into the void ble_begin_debug(); adding true in lib_aci_init(&aci_state, true); in the file RBL_nRF8001.cpp as suggested.

The result is this one (Arduino IDE Serial Monitor output tail lines)

You can see all the Arduino output for echo.js here and the Arduino output for Android BLE Controller Simple chat here. Just for sake of clarity here is the output of echo.js node application.

Let me know if there are some other debug information that I can provide.
