I'm doing tcc, the project is to create a java desktop application and make it communicate with an android application. As this communication will be in a room for example, always in the same environment, I thought of using Bluetooth. I did a test with BlueCove in java, however you need to install the bluetooh driver in the machine. My question is as follows, if the application is to run on different operating systems or the same system but with different versions how to handle the problem of installing the bluetooh driver? If the machine is old and does not have a plate to accept the bluetooh. How far would it be feasible to use it? Thanks.
