Saturday, June 27th, 2009

(1) Bluetooth Access Point based solution, MSP1000
(2) Bluetooth USB Adapter based solution, UD100 
 
SENA’s Bluetooth Access Point supports up to 28 simultaneous connections. We do have successful large-scale implementations of this application in Korea and Europe. Enclosed, please find a presentation that details on how-to implement “Bluetooth Proximity Marketing” application using Sena’s MSP1000. 

MSP1000 Access Point

MSP1000 Access Point

 
SENA’s Bluetooth USB Adapter runs on class 1 type of specification and incorporates Bluetooth 2.0 with Enhanced Data Rate (EDR) support that offers increased data transfer rates up to 3 Mbps. Nominal wireless transmit distance is 300 meters (984 feet) and can be extended up to 1000 meters (3280 feet) using optional patch antenna.

Wireless Bluetooth Car Diagnostic System

Monday, June 1st, 2009

 Automotive data acquisition can be simple and efficient using SENA Bluetooth devices.

When a car equipped with Parani-ESD100 stops at the parking lot, Parani-MSP1000 tries to find it using previously set IAC(Inquiry Access Code). Once it’s found, Parani-MSP1000 makes Bluetooth connections to Parani-ESD100.

Product : Parani-MSP1000
Connects Bluetooth devices to Ethernet
Supports various host modes for TCP/IP and Bluetooth communication
Bluetooth v2.0+EDR
Supports 7/14/28 Bluetooth connections
Searches specific devices using IAC(Inquiry Access Code)

 

Automotive data is sent from Parani-ESD100 to Parani-MSP1000 via Bluetooth.

  • Product : Parani-ESD100
    Low Cost OEM Bluetooth-Serial Module
    Bluetooth v1.2 Class 1
    Built-in antenna

 

 

 

Parani-MSP1000 sends the automotive data to Database server over TCP/IP network.

 

 

 

 

 

The administrator connects to the Database server, and each car can be diagnosed using the following data stored in the Database server.

  • Mileage
    Fuel efficiency
    Maximum speed
    Error code
    Other automotive info like engine temperature 
     

 

 

Benefits
Car can be diagnosed automatically
Exact diagnosis is possible using accumulated automotive data
Removing the long cable and complex wiring of typical automotive diagnosis using Bluetooth

Car Diagnostic System using MSP1000 and ESD100

Monday, June 1st, 2009

1. Overview

MSP1000 searches car diagnostic devices periodically. MSP1000 tries to connect to the car diagnostic device via Bluetooth SPP when it is found. Once Bluetooth connection is completed, MSP1000 tries to connect to the car diagnostic server over TCP/IP network. In this way, the car diagnostic data is stored to the server.

MSP1000 uses IAC (Inquiry Access Code) to search specific devices.

PC(Server) -(Ethernet)- MSP1000 -(Bluetooth)- ESD100 -(Serial)-Car Diagnostic device

2. MSP1000 System Configurations

2.1 Pairing Mode configuration

 

Pairing mode is set to ‘Connector’ for MSP1000 to search Bluetooth peripherals.

Above configuration, MSP1000 searches only the device which IAC is ‘0×9E8B20′ and connects to it.
– Scan interval :

Parani-MSP1000 searches nearby Bluetooth devices per this interval. This value means the time Parani-MSP1000 requires to recognize a new Bluetooth device.

Attention : Too short scan interval makes the data communication speed slower.

– Scan mode :

Parani-MSP1000 can search Bluetooth devices around it using IAC or device name.

– Inquiry access code (IAC) :

The range of IAC value is between 9e8b00 and 9e8b3f(Hexadecimal). Most of Bluetooth devices have the general IAC value – 9e8b33. But in case of the general IAC value, Parani-MSP1000 may find too many Bluetooth devices to connect besides what it really wants. To solve this problem, it is efficient to use a specific IAC or a user-defined IAC.

To use a specific or user-defined IAC, the IAC of target device that is going to be connected by Parani-MSP1000 must be modified.

– Remote device name :

Parani-MSP1000 searches the device whose name is the same as the value of ‘Remote device name’.

2.2 Port configuration

Select ‘Network service configuration’.

This configuration shows the TCP connection of server (192.168.1.248:7001).

Please refer to ‘5.5.6 Network service’ section of Parani-MSP1000 manual.

3. Configuration of ESD100

Using following commands, ESD100 can be searched through specific IAC by Parani-MSP1000.

– AT+BTMODE,3 : Set to MODE3

– ATS45=9E8B20 => Set IAC to 9E8B20

The ‘CONNECT’ message confirms that ESD100 and MSP1000 are in connection.

Remote upload & download system for CNC lathes

Friday, May 1st, 2009

Application:
The customer wants to build a system to upload and download CNC lathe working data remotely from a central control room.

To achieve this goal, the Control software, Parani-SD100, and Parani-MSP1000 are used for this system. Parani-SD100s are connected to serial ports of CNC lathes (CITIZEN – CINCOM L20) and Parani-MSP1000’s communicate with control software over TCP/IP network.

There are 103 CNC lathes in two factories (about 30 CNC lathes on each floor), to be remotely controlled from the central control room.

System Configuration
PC (Central software, Serial/IP used) – (Ethernet) – Parani-MSP1000 – (Bluetooth) – Parani-SD100 – (Serial RS232) – CINCOM L20(CNC lathe)

The serial parameters of CNC lathe: 9600, 7, Even, 1, HWFC – DB25 (Straight cable)

7 data bits and even parity are used, so Parani-MSP1000 is used. (MSP100 is not applicable)

Configuration of Parani-MSP1000
Set Pairing mode to ‘Custom’. Only specific Parani-SD can connect to Parani-MSP1000.

Pairing mode configuration

Pairing mode configuration

Set ‘Port pairing mode’ to ‘Acceptor’, and type in the BD address of Parani-SD.

Port #1 Configuration

Port #1 Configuration

 
Set ‘Network service mode’ to ‘Server’ and set ‘Local port number’ to connect to PC and to communicate with Serial/IP program.

Network Service Configuration

Network Service Configuration

Since Parani-SD does not support 7 data bits, enable Parani-MSP1000 serial data conversion feature between 7 data bits and 8 data bits.

Port #1 Configuration

Port #1 Configuration

Configuration of Parani-SD100
CNC lathe uses following serial parameter.

Baud rate : 9600 / Data bits : 7 / Parity : even / Stop bit : 1

First, search Parani-MSP1000 with ParaniWin. Once connected, then disconnect it.

ParaniWin

ParaniWin

Set operation mode to ‘MODE1′. The Parani-SD100 is always trying to connect to Parani-MSP1000.

Set command response to ‘OFF’, because CNC lathe does not handle the response of AT command.

Configuration of Serial/IP
Using the virtual COM port of Serial/IP, there is no need to customize legacy serial program.
