I have deleted your 2 replies to another similar topic. Please do not add your questions to the end of other people's topics. @pert has already pointed out the forum guide to you, please read it. You are more likely to get a useful answer if you follow the guide. At the moment you have an image of code instead of actual code and, without a schematic, no one knows how you have connected whatever it is you have. Also needed, at the very least, details of what you have, such as the Arduino board you are using and details of this 'GM65' you have.
Thank you.
Please post a link to the scanner datasheet.
Which controller is used?
Schematics please.....
If you put: Serial.println("Gm65 has data."); inside the if(GM65.available()) you will be able to tell if ANY characters arrive from the GM65.
Did you scan the QR Code in the datasheet that enables serial output?
i tried including a string message inside but nothing turned up, let me try scanning QR code in the data sheet... Your input is much appreciated
wow it actually worked thank you so much @johnwasser .. You just saved my GPA... Thank you
Always good to read the manual.
