App crash or get disconnected after 6-7 tickets
"react-native": "0.70.6",
"react-native-esc-pos-printer": "^2.3.0",
This is my code
componentWillUnmount() {
if (this.unsubscriber) {
this.unsubscriber()
}
}
async monitorPrinter() {
try {
console.log('Start monitoring ...');
this.setState({ loading: true })
await EscPosPrinter.init({
target: this.state.printer.target,
seriesName: getPrinterSeriesByName(this.state.printer.name),
});
}
catch (error) {
console.log(error)
}
this.unsubscriber = EscPosPrinter.addPrinterStatusListener((status) => {
this.setState({ status: status, loading: false })
if (status.connection === 'DISCONNECT') {
this.context.setAppState(`No device connected`)
this.setState({ status: null })
}
})
if (this.state.status === null) {
EscPosPrinter.startMonitorPrinter(5)
.then(() => console.log('Start monitor success!'))
.catch((e) => this.setState({ error: e.message, loading: false }))
}
}
scanPrinter = () => {
this.setState({ loading: true, error: null })
EscPosPrinter.discover()
.then((printers) => {
if (printers.length === 0) {
this.setState({ loading: false, error: 'No printers found. Please try again.' })
}
if (printers[0]) {
this.setState({ printer: printers[0], loading: false })
this.context.setAppState(`Successfully connected to ${printers[0].name}`)
this.context.setPrinter(printers[0])
console.log('Connected');
this.monitorPrinter()
} else {
this.setState({ loading: false, error: 'No printers found. Please try again.' })
}
})
.catch(console.log);
}
