serial connection with RFID equipment

Thu Sep 12, 2019 8:42 pm

Good afternoon, how are you?

I'm new to pi, and I need your help.

I am developing software that communicates with the serial port of an RFID device, on other systems (win) I was successful, but I would like to use the raspberry.

My question is, when connecting the usb cable to the raspberry port, I go to the /dev folder and the ACM0 file is created.

I checked through usbview and the connected RFID equipment was recognized perfectly, but when making the connection (tmr:///dev/ACM0) nothing happens.

I enabled the serial communication through the central, restarted the pi but was unsuccessful

Does anyone know what may be happening?

Sorry for my English

I don't know if this will work but I'd try using /dev/ttyACM0 for the port name.
