Picture of Weather proof, Bluetooth capable RFID reader
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.

hello,

SerialUsbBlueSmirfConfig.zip

and

Serial.zip

are not working. any help?

tamberg (author)  lekirst2 months ago
Hi, what exactly did you try and what's error message?
lekirst tamberg2 months ago

rfish.net website seems to be down..

This domain name has been registered with Gandi.net

It is currently being parked by the owner

tamberg (author)  lekirst2 months ago

Thanks. Will have a look.

lekirst tamberg2 months ago

okay great, hope you can get the downloads working again.

lekirst lekirst1 month ago

the links are still not working. :(

tamberg (author)  lekirst1 month ago

Sorry for the long wait. Should be fixed now. Cheers, Thomas

tamberg (author)  lekirst1 month ago
Thanks for letting me know. Got to fix my domain / hosting. Will take some days, sorry.

hi Tamberg,

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.

tamberg (author)  shruti.kamtekar4 months ago

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

hi,

I should connect the RFID ID12
and the BLUESMIRF gold Bluetooth module to the ID12 breakout board ad
shown in the tutorial. For configuration part i need to connect the
bluetooth module to the android phone using bluetooth serial profile and
the configuration would be done.

tamberg (author)  shruti.kamtekar4 months ago

Yes. There's not much to configure with SPP, as far as I remember.

HI,

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.

is there a cheaper RFID and bluetooth module i could use.

and can you please give the detail about SPP since i have no idea about it.

tamberg (author)  shruti.kamtekar4 months ago

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.

can i configure and connect other rfid and bluetooth module in the similar way

tamberg (author)  shruti.kamtekar4 months ago

Yes. All serial modules work more or less the same.

can u provide me with more detailed information on bluetooth serial profile or any source from where i can understand it.

tamberg (author)  shruti.kamtekar4 months ago

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

I loved this article and its step by step tutorial about making water proof RFID tag. I would like to make this <a href="http://trakaid.com/wp-content/uploads/2014/01/tk2013-03-dc-on-metal-rfid-asset-tag.pdf">TRAKAID On-Metal RFID Asset Tag</a>..

great little tutorial, curious if you ever tried this with a 125khz ACTIVE rfid tag?

Curious what kind of increased rage it would have....if you know, I'd appreciate the info

tamberg (author)  skeet10310 months ago

Hi Skeet103, never had access to an active 125khz tag. Nice idea, though. Cheers, tamberg

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.

Thanks, F.
tamberg (author)  fsaffery1 year ago
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.
fsaffery1 year ago
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 "☺☻♥♣4F" 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.

- The chip is set to ASCII mode.
- 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).


Thanks, F.
tamberg (author)  fsaffery1 year ago
Hi, which chip are you referring to? Maybe the baud rate is not set correctly?
nadjibfoley2 years ago
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.
tamberg (author)  nadjibfoley2 years ago
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,
Thomas
Greeting, Just FYI, I tried to download your SerialUSBbluesmirf.zip and it turned out like this

Fixed! Thank you very much. Regards, tamberg
Hello, i would like to buy 1 premade.
Can you do this?
How much cost and ship to Florida, USA.

Thank you
tamberg (author)  itismycountry2 years ago
Hi, thanks for the request! I sent you a private message.

Hi,
Is it possible to do the same thing with a wifi module instead of Bluetooth?
Thanks.
tamberg (author)  LIMAMIN3 years ago
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
... http://rfish.net/download/Serial.zip
it says "Forbidden" (error code 403)
tamberg (author)  acti3 years ago
Fixed, thanks.
Did you write the software yourself?
tamberg (author)  jeffjeffwong3 years ago
Hi jeffjeffwong,

yes, I did. That said, there's very little software included here. For a real application you'd probably need some extra code.

Cheers,
tamberg

I would like to know if this RFID reader has been tested on and whether it is known to work with a Mac?
Cheers,
Stephen in Montréal
tamberg (author)  sghantous4 years ago
Hi sghantous, the reader communicates via Bluetooth and should work with a Mac, but I never actually tested it. The .NET test program probably needs Mono and some additional tweaking to run on a Mac. Cheers, tamberg
