Hello,

If you have not already set up serial over Bluetooth:

> [@Communication over laptop's Bluetooth](https://discourse.processing.org/t/communication-over-laptops-bluetooth/14056):
>
> How can I send & receive data through the laptop’s bluetooth? For example, have an android sketch communicate with a java sketch (running on the laptop) over bluetooth? It’s fairly straightforward how to do the android side (with Ketai library), but how can I implement the PC side? Note: I’m interested in using the laptop’s embedded Bluetooth. Not in any solutions involving 3rd party modules (i.e. arduino + Bluetooth module over Serial).
