I have a project that needs to integrate with a 2D barcode reader using either Bluetooth or having the barcode scanner connected via USB. I've searched for BLE barcode scanners but they are hard to find - I found just two that seem usable.
I've searched the Net but cannot find anything specific. Can anyone advise on the feasibility of using a 2D barcode reader with Arduino and BLE? There is not much I can find on Youtube for this. The MCU simply needs to get the number scanned by the barcode reader.
I purchased an HM-10 which I have connected to an Arduino Mega. The HM-10 is working and I can receive data sent from an Android app, but I don't know how to use the HM-10 for connecting to a device like a BLE barcode scanner.
Also it seems like the HM-10 acts like a Bluetooth client where other devices (like an Android phone or tablet) can "connect" to it. But I think I need it the other way around - ie. use the HM-10 to scan for devices and connect to the reader.
