Before these, an external router (or smartphone as a hotspot) had to be used to create a small ad-hoc network, to which the microcomputer and the client PC had to connect.
Antonio saw this solution as impractical and inefficient. Instead he configured the microcomputer to act as an access point: on powering it exposes an SSID to which any WIFI capable device can connect.
In this way, not only do we eliminate unnecessary intermediate in the network, but also the portability of the system is considerably improved. For example, to capture in an external environment you only need to carry a laptop with charged batteries.
Thanks to Antonio for such a huge boost!
