I have a jailbroken iPhone running iOS 5.1.1. I am using Xcode 4.3.2, and I am developing an app that will hopefully talk to a Parallax RFID reader. Essentially I want users of the app to be able to login using an RFID card as opposed to inputting their username and pin, but I still have a lot of work to do to get this done.
The app I am developing is being loaded onto the phone via Cydia, so accessing the serial port /dev/tty.iap on the phone shouldn’t be a problem.
I created two files Seiral.h and Serial.c for opening the serial port.
The code for Serial.c is similar to what is found in the devdot tutorial, and I think I am sucessfully opening the serial port because I am getting this message in the console:
Aug 18 19:33:34 3GS KegCop[520]: The serial data is 16
How would I read the RFID badge number being scanned on the Parallax reader?
I am using an Arduino to talk between the iPhone and the RFID reader. When the RFID badge is scanned, it sends the badge number out via the serial out on the Arduino, but I am not sure how I would read the data on the iPhone side of things.
I am currently still working on this solution, but I did manage to find a good serial console app with a tutorial, that will work as a starting point for a foundation for getting the serial communication working within the app I am currently developing.
