Weather proof, Bluetooth capable RFID reader

Step 2 Configure the BlueSmirf module via USB

Connect the BlueSmirf to the USB to serial adapter as follows (you might use headers to connect female jumper cables to the female connector of the USB to serial adapter):

• VCC to 3.3V
• GND to GND
• TX-O to RX-I
• RX-I to TX-O

Then plug the USB into your PC (the following instructions apply to Windows XP and might differ for other operating systems). The red LED on the BlueSmirf should now blink.

Press "<Windows key>-R" on your keyboard to open the "Run" command line, type "devmgmt.msc" and press "<RETURN>". This opens the Device Manager. Open the node "Ports (COM & LPT)" in the device tree. There should be a node called "USB Serial Port (COM<X>)" e.g. COM17. Write down the COM port number (to talk to the BlueSmirf module over USB we will open a connection to this COM port).

Download SerialUsbBlueSmirfConfig.zip (requires .NET 2.0; source included for educational purpose) and unzip it.

Edit SerialUsbBlueSmirfConfig.bat (right click, "Edit") to match your COM port number and baud rate (default for BlueSmirf Gold is 115200 baud) and save the changes.

Start SerialUsbBlueSmirfConfig.bat and as soon as the program displays your COM port in the command shell, type the following commands (BlueSmirf's response shown in italic):

• $$$<RETURN>
• CMD
• SU,96<RETURN>
• AOK
• ---<RETURN>
• END

When in command mode, the BlueSmirf's red LED starts to flash faster. After leaving command mode, the BlueSmirf Bluetooth module is set to 9600 baud which is necessary to communicate with the ID12 RFID reader.

(Note: If you want to use SerialUsbBlueSmirfConfig.bat again don't forget to change it to 9600.)

I have tried to configure it with a regular usb-serial cable adapter: 

It doesnt works, works only with ftdi usb-serial adapter. Its confirmed in the description of  bluesmirf module in sparkfun website. TTL type only.

Thanks Tamberg, my device is working fine.
