Post Codatech RFID read error
I am currently using the Codatech RFID sensor in a school project and using the RobotC Driver Suite. For the most part my program works, however, every so often the program returns an error message about the RFID sensor.

I used this

Code:
          
     CTRFIDsetContinuous(CTRFID);

    if (!CTRFIDreadTransponder(CTRFID, transponderID)) {
         eraseDisplay();
         nxtDisplayTextLine(3, "Error reading");
         nxtDisplayTextLine(4, "from sensor!");
         wait10Msec(5000);
         StopAllTasks();
       }


from the example program found in the driver suite.

The program will last for about 4 or 5 scans before returning the message. Any advice would be appreciated if you need to see my code just let me know and ill be happy to post it.

The sensor is a bit wonky at the best of times, so your program will have to deal with the occasional error. The developer has promised a new firmware for a few years now but no dice.
