Version Differences for OPN2002 - Opticon Technical Support Portal

:So Unix machines - which is what a Mac essentially is - have their serial ports implemented in a different way, from what you might be used to with a Windows PC. When a serial device is connected to the Mac, and the kernel is able to map a valid kernel driver to it, a POSIX device file is created under /dev/ for that serial port. After that, programs can read and write to this file, which becomes the same thing as reading and writing from a serial port. Windows uses a similar concept with COM (serial) ports, just implemented slightly differently.

:Now, when you connect the OPN2002 to the Mac using Bluetooth VCP (SPP), one of these POSIX device files is created in /dev/. To finish the initial connection, that file must be opened with some program - namely yours. To test this yourself, you can use the Terminal program, and run the 'cat' command against the new file that was created under /dev/ while the pairing process was taking place. After that, the initial pairing should complete successfully.

'''I have the OPN2001 Simulation Application installed on my OPN2002. The OPN2002 seems to behave as an OPN2001 in USB mode, but how do I know if the OPN2002 has stored data or not when using Bluetooth?'''
