To make conversation with the device, they(paytm) should have provided you the sdk or api, right? Use them to generate on the device and if you don't have then ask their support to get that.

Thank you, Amit Ji!

Yesterday, I had meet with Paytm DQR Team and they have shared some SDKs which will communicate between POS system and DQR display device using serial port communication.
