This instructable connects the popular BlueSmirf Bluetooth module to the ID12 RFID reader and shows how to make a dust and water resistant (IP55) RFID reader that sends IDs to your PC or mobile phone over Bluetooth radio without an additional micro controller and without an external power source. Created as a prototype for an online swim lap counter system named Rfish, it can be used for any project in need of a self contained, weather proof RFID reader.



Material

Tools

  • Cutter
  • Soldering iron
  • Helping hands

Step 1: Solder headers to the BlueSmirf Bluetooth module

<p>One more question (for the time being): Can I use 1.5v button cells to make this work? Obviously it won't have the life of the AAs but would it work at all? And I don't suppose you know if there's a battery case designed for three 1.5v button cells?</p>
Not sure. Google Bluetooth Low Energy or BLE for something using less energy. There are probably also low power RFID readers, e.g. the one used by Poken.com (a toy to swap contacts, at least they used to do that).
<p>Some of the software links appear to be dead. Where can I obtain the software needed for this?</p>
<p>Should be fixed now. Thanks for letting me know.</p>
<p>This link still appears dead: http://rfish.net/download/SerialUsbBlueSmirfConfig.zip</p>
<p>Maybe a caching issue. Just add www. in front of rfish.net</p>
<p>Is there a program that would allow this to make the phone vibrate when different RFIDs were present? So you could have RFIDs numbered and each one would cause a series of vibrations?</p>
You could use this Android API to vibrate in a pattern: https://developer.android.com/reference/android/os/Vibrator.html
<p>Great article still I wanted to know can we use any other bluetooth module instead of bluesmirf gold bluetooth module</p>
Sure, you can use any other Bluetooth module that provides the Serial Protocol. Cheers, Thomas
<p>hello, </p><p><a href="http://rfish.net/download/SerialUsbBlueSmirfConfig.zip" rel="nofollow">SerialUsbBlueSmirfConfig.zip </a></p><p></p><p>and</p><p></p><p><a href="http://rfish.net/download/Serial.zip" rel="nofollow">Serial.zip</a></p><p>are not working. any help?</p><p></p>
Hi, what exactly did you try and what's error message?
<p>rfish.net website seems to be down..</p>This domain name has been registered with Gandi.net<p>It is currently being parked by the owner</p>
<p>Thanks. Will have a look.</p>
<p>okay great, hope you can get the downloads working again.</p>
<p>the links are still not working. :(</p>
<p>Sorry for the long wait. Should be fixed now. Cheers, Thomas</p>
Thanks for letting me know. Got to fix my domain / hosting. Will take some days, sorry.
<p>hi Tamberg,</p><p>i would like to read the rfid tag and send the tag id via bluetooth to an android phone. this tutorial does not teach how to connect it to phone.also how to configure the rfid reader and bluetooth module.</p>
<p>Hi, the Bluetooth module in this project just forwards whatever the RFID reader module sends to it. Simply connect to the Bluetooth module using the Bluetooth serial profile (SPP). The standard Android Bluetooth library should do the job. Cheers, Thomas</p>
<p>hi,</p><p>I should connect the RFID ID12 <br> and the BLUESMIRF gold Bluetooth module to the ID12 breakout board ad <br>shown in the tutorial. For configuration part i need to connect the <br>bluetooth module to the android phone using bluetooth serial profile and <br> the configuration would be done.</p>
<p>Yes. There's not much to configure with SPP, as far as I remember.</p>
<p>HI,</p><p>I have to actually read RFID tag number of every student who boards the bus which has a RFID reader and send their parents message about the child boarding the bus.i am planning to send the tag number to the phone.</p><p>is there a cheaper RFID and bluetooth module i could use.</p><p>and can you please give the detail about SPP since i have no idea about it.</p>
<p>Sounds like a great project. In the meantime there are some cheaper RFID readers and way cheaper Bluetooth modules. If price is critical, check something like Ali-Express.</p>
<p>can i configure and connect other rfid and bluetooth module in the similar way</p>
<p>Yes. All serial modules work more or less the same.</p>
<p>can u provide me with more detailed information on bluetooth serial profile or any source from where i can understand it.</p>
<p>Just remembered they also call it RFCOMM. See https://en.wikipedia.org/wiki/List_of_Bluetooth_protocols#RFCOMM and for Android https://developer.android.com/reference/android/bluetooth/BluetoothSocket.html</p>
<p>Oops, here's a shortened version of the Android link: http://goo.gl/Wlq1yI</p>
<p>I loved this article and its step by step tutorial about making water proof RFID tag. I would like to make this &lt;a href=&quot;http://trakaid.com/wp-content/uploads/2014/01/tk2013-03-dc-on-metal-rfid-asset-tag.pdf&quot;&gt;TRAKAID On-Metal RFID Asset Tag&lt;/a&gt;.. </p>
<p>great little tutorial, curious if you ever tried this with a 125khz ACTIVE rfid tag?</p><p>Curious what kind of increased rage it would have....if you know, I'd appreciate the info</p>
<p>Hi Skeet103, never had access to an active 125khz tag. Nice idea, though. Cheers, tamberg</p>
Oh I have a number of ID20 and ID12 chips floating about my office each with pins 7 and 1 connected (setting to ASCII). The Bluesmirf is set to 9600 Baud. <br> <br>Thanks, F.
All I know about the ID12 is what's written here. Maybe your BlueSmirf has some settings that cause the problem, as it was probably not in the default state. Try to go through the setup steps of this Instructable, maybe with another baud rate. And check the baud rate in your code, too.
Hey there I know its been a while since you made this project but quick question. When I connect to a PC and scan a card im getting &quot;☺☻&hearts;&clubs;4F&quot; random characters as its trying to show ASCII of data thats just not there. Now I checked the .cs file and I couldnt see that you were changing the bits into any form of data, just writeln them. <br> <br>- The chip is set to ASCII mode. <br>- The reason I ask is I have coded something for android which does output characters but not the unique card ID normally just 002000000 or the like so im trying to find if its my code thats not correct or if its something to do with my circuit. (Had some problems way back when I connected the chip via a wire to the phone with power and it not sending the data correctly). <br> <br> <br>Thanks, F.
Hi, which chip are you referring to? Maybe the baud rate is not set correctly?
Hi, I know this is an old pot but just wondering if you can remember roughly how much this cost, and the distance that it would work at asI know most RDIF systems are quite short in terms of reading distance.
Hi, the parts are all linked on the first page. There are cheaper Bluetooth modules on Ebay, around 10$ if I remember correctly. The reading distance is very short (you have to touch the reader) which indeed is quite a disadvantage for most applications. Regards, <br>Thomas
Greeting, Just FYI, I tried to download your SerialUSBbluesmirf.zip and it turned out like this <br /> <br />403 Forbidden <br /> <br />Code: AccessDenied <br />Message: Access Denied <br />RequestId: 4AB03E36B05CC9D4 <br />HostId: NrN3vGkopox3PnzYj8nNCefc2JJsDFAStAOS1hnyi2StP+4hlPj19AvQdTs0yzSf <br />
Fixed! Thank you very much. Regards, tamberg
Hello, i would like to buy 1 premade. <br>Can you do this? <br>How much cost and ship to Florida, USA. <br> <br>Thank you
Hi, thanks for the request! I sent you a private message.
Hi,<br>Is it possible to do the same thing with a wifi module instead of Bluetooth?<br>Thanks.
LIMAMIN, that could work. There should be Wifi modules supporting serial communication (UART). However the setup would probably be different and the system might require more power. Also, I'm not sure if there's any interference between RFID and Wifi, but probably not. Cheers, tamberg
The download link for Serial.zip is broken <br>... http://rfish.net/download/Serial.zip<br>it says &quot;Forbidden&quot; (error code 403)<br>
Fixed, thanks.
Did you write the software yourself?
Hi jeffjeffwong,<br><br>yes, I did. That said, there's very little software included here. For a real application you'd probably need some extra code.<br><br>Cheers,<br>tamberg
I would like to know if this RFID reader has been tested on and whether it is known to work with a Mac?<br>Cheers,<br>Stephen in Montr&eacute;al
