What does the Arduino do with the command from NodeJS? Does it read it and discard it if there's nothing to do? Or do the commands build up in the serial buffer?
The arduino will analyze if its a valid command, if so will try to read the UID of the RFID card and send back on the serial port, if no card, no data will be sent.
You may be running out of memory. Your PC likely has a lot more memory than the 1 GB Raspberry Pi. Maybe check the output of the "free" command periodically.
I will check that as well!!
