How do I connect a TCP/IP (Ethernet) QR‑code scanner to Mendix and store the scanned data?
0
I need to integrate an industrial QR‑code scanner that communicates over TCP/IP (Ethernet) with my Mendix app. The goal is to capture each scanned QR code and write it directly to a Mendix entity. I’ve gathered a list of the communication protocols the scanner supports (TCP/IP,, HTTP POST, , etc.), but I’m not sure which approach is the most practical—or how to wire it up inside Mendix. Has anyone connected a networked scanner like this before? I’d love advice or examples on: Choosing the best protocol for Mendix. Creating the listener/service in Mendix to receive the data. Persisting the QR string to a database entity. Handling multiple scans per second and connection errors. Any pointers, sample microflows, or marketplace modules you can recommend would be greatly appreciated! Thanks in advance.

Hello Chandani,
In the past i have worked on an application where we used MQTT, we used the following module to receive/process the messages https://marketplace.mendix.com/link/component/119508.
