This is a library for connect rfid using native module in React Native app
npm install react-native-rfid-connectorThis library helps us listen to the state of Bluetooth and connect it with an RFID reader device. Get data from RFID TAG
$ npm install react-native-rfid-connector --save
or$ yarn add react-native-rfid-connector
If using react-native < 0.60$ react-native link react-native-rfid-connector
javascript
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"}

`List status of
DOTR_EVENT`:
- onConnected
- onDisconnected
- onLinkLost
- onTriggerChaned
- onInventoryEPC
- onReadTagData
- onWriteTagData
- onUploadTagData
- onTagMemoryLocked
- onScanCode
- onScanTriggerChangedIn this document we will focus on
`onReadTagData `. This status will receive when we found any RFIDTAG.Structure response form event listener like this:
`javascript
{
type:"DOTR_EVENT",
status:"onReadTagData",
data:{
tagData:"000",
epc:"100001"
}
}
