I'm currently developping a react-native app which need to read Barcode, QrCode and RFID tags.
It need to support various scanner. Currently I'm trying to use a RFD40 premium plus and a RFD85 within the app.
I use the react-native-bluetooth-classic module to.
So far I manage to connect both of the devices to the app.
The issue is that I don't manage to get the data from the scanner. When I perform a RFID scan nothing happen and when I scan a barcode or QrCode the scanner emit 1 bip with a green light then a few seconds later it emit 4 bips with a red light (one light peer bip).
In my code, when I use the method onDataReceived wich should trigger as soon as I scan something nothing happend and when I use the method read and available it seems to have no data.
I someone any idea of why I don't manage to get data and what does these 4 bips means ?
