SEN0486 barcode set up
![userHead](https://dfimg.dfrobot.com/dfPortrait2.png)
How would I set up the SEN0486 to scan a barcode, I can't find any resources online.
Same here.
Both sample codes not working for me on my esp32
no recognition from the qr code scanner

Hi
Can you post your code, compilation error (if it happened), and output (serial or I2C) here?
Hello,
thanks for the quick response.
no compiling error - both example codes work in pio.
Use Pin 16 and 17 for TX/RX on a ESP32 Lora 1.3
#define FPSerial Serial1 //also with HardwareSerial
…
Serial1.begin(9600, SERIAL_8N1, /*rx =*/16, /*tx =*/17);
and for I2C 21 and 22.
No output on any interface.
Should be indication light work without pinning the rx/tx pin?
Because on a 3.3v power supply the led is breathing but no indication of recorgnize code.

@Raj.Kunwor any update on that?
Have the same issue with a esp32. UART and I2C not showing up and the led just breathing.
Any further assistance ?

What board are you using? Please note that the wiring of the sensor needs to correspond to that of the selector switch.

No…they are not working. My device just changes colors and never reads any barcode of any type.

Are the sample codes not working?
