My connecting my usb wireless scanner with raspberry pi zero w then try to display data on nodered. However, the data i get is as shown in the picture. How can i convert it to readable number or string?
What did you scan to get that value?
No what actual barcode did you scan? What was its value. Do you have a photo of the barcode?
Also, show us the value as it arrives ( before it is processed by any other nodes)
Ps, in your screen shot, buffer parser is not connected.
If you want accurate help, accurate & complete info is necessary.
