BEEPER and LED Configurations Tutorial

RFID SDK for MAUI

Applicable devices : Handheld Readers

Overview

This Tutorial provides a walk-through of the steps to perform LED configuration MAUI RFID SDK

Create the Project

  • Start by creating a new project in Visual Studio. For help, see the Create Project.
  • Refer Hello RFID to prepare basic setup to work with RFID Reader and then follow this guide

Details

Application can use SetLedBlinkEnable to blink host device LED and BeeperVolume to BEEP In the host device for each tag read event

Beeper volume can be controlled with four volume levels

  1. BEEPER_VOLUME.HIGH_BEEP
  2. BEEPER_VOLUME.MEDIUM_BEEP
  3. BEEPER_VOLUME.LOW_BEEP
  4. BEEPER_VOLUME.QUIET_BEEP

Beeper Volume Settings Compatibility for Devices
BEEPER_VOLUME HandHeld Readers Mobile Computers
BEEPER_VOLUME.HIGH_BEEP ✔ ✔
BEEPER_VOLUME.MEDIUM_BEEP ✔ ✖
BEEPER_VOLUME.LOW_BEEP ✔ ✖
BEEPER_VOLUME.QUIET_BEEP ✔ ✔

Setting it up for enabling the LED

SDK supports setting host LED indication using following API 


    
    /* Disbale Led */
    rfidReader.Config.SetLedBlinkEnable(false);

    /* Enable device Led */
    rfidReader.Config.SetLedBlinkEnable(true);

Setting it up for enabling the Beeper

SDK supports setting host Beeper indication using following API 


    /* Disbale beeper */
    rfidReader.Config.BeeperVolume = BEEPER_VOLUME.QUIET_BEEP;
    
    /* Enable device beeper */
    rfidReader.Config.BeeperVolume = BEEPER_VOLUME.HIGH_BEEP;

Only for RFD40/90 readers volume control can be set using the following:


int sledBeeperVolume = 2;
BEEPER_VOLUME sledBeeper = BEEPER_VOLUME.HIGH_BEEP;
sledBeeperVolume.VolumeControl = sledBeeperVolume;
rfidReader.Config.BeeperVolume = sledBeeper

Volume control value can be given from 0 - 15 for LOW, MEDIUM and HIGH. Value 0 is for backward compatibility (legacy support). Fine tuning of volume happens from 1 to 15.

NOTE: User has to make sure supported firmware is used for this feature to work.
