react-native-rfid-connector v2.0.2

React-native-rfid-connector

This library helps us listen to the state of Bluetooth and connect it with an RFID reader device. Get data from RFID TAG

Getting started

$ npm install react-native-rfid-connector --save or $ yarn add react-native-rfid-connector

Mostly automatic installation

If using react-native < 0.60 $ react-native link react-native-rfid-connector

Usage

import RfidConnector from 'react-native-rfid-connector';

componentDidMount() {
    RfidConnector.getCurrentState().then(this.handleConnection)
  }

  componentWillMount() {
    RfidConnector.addEventListener('change', this.handleConnection);
  }

  componentWillUnmount() {
    RfidConnector.removeEventListener('change', this.handleConnection)
  }

  handleConnection = (resp) => {
    const {type} = resp;
    switch(type){
      case 'BLT_STATE_CHANGE':
        //resp: { type:BLT_STATE_CHANGE, status:"on"}
        this.setState({connectionState:resp.status});

        break;

        case 'BLT_DISCOVERY_STARTED':
          //resp: { type:"BLT_DISCOVERY_STARTED"}
          break;
        case 'BLT_DISCOVERY_DEVICE':
          //resp: { type:"BLT_DISCOVERY_DEVICE", device_info: {device_address: "6C:40:08:AA:F2:0B", device_name: "Hangnta"}}
          const newList = [...this.state.listDevice,resp.device_info];
          this.setState({listDevice:newList})
        break;

      case 'BLT_DISCOVERY_DEVICE_FINISH':
        //resp: { type:"BLT_DISCOVERY_DEVICE_FINISH"}
        break;
        case 'DOTR_EVENT':
        //resp: { type:"DOTR_EVENT",status:"",data: any}
          break;
    }

Start Scan bluetooth devices:

RfidConnector.startScanBlueTooth().then(rsp=>{
            console.log("scan rsp",rsp);
          }).catch(err=>console.log("err",err));

Stop Scan bluetooth devices:

RfidConnector.stopScanBlueTooth().then(rsp=>{
            console.log("stop scan",rsp);
          }).catch(err=>console.log("err",err));

Filter bluetooth devices with prefix name:

RfidConnector.setListFilterBlueToothPrefix(["HQ_UHF_READER","TSS91JJ-","DOTR2100-","DOTR2200-","TSS2100","TSS2200","DOTR3100","DOTR3200","TSS3100","TSS3200"]);

Connect to specific devices address to read tag:

RfidConnector.connectToDevice("device address");

Disconnect to current device:

RfidConnector.disConnectToDevice().then(msg=>console.log(msg)).catch(err=>console.log(err));

List status of DOTR_EVENT:

• onConnected
• onDisconnected
• onLinkLost
• onTriggerChaned
• onInventoryEPC
• onReadTagData
• onWriteTagData
• onUploadTagData
• onTagMemoryLocked
• onScanCode
• onScanTriggerChanged

In this document we will focus on onReadTagData. This status will receive when we found any RFIDTAG.Structure response form event listener like this:

{
type:"DOTR_EVENT",
status:"onReadTagData",
data:{
    tagData:"000",
    epc:"100001"
    }
}
