I was testing a system based on some devices connected to a WiFi network. There are 3 devices that make part of the system: A raspberry Pi, an ESP32 and a laptop PC. The raspi acts as a Apache server and the ESP32s send requests for it. I use the laptop PC on the same network in order to see the data via a webpage.
During the test I could not connect to the network using my laptop, neither the raspberry Pi, but the ESP32s connected via DHCP ok.
Since I have little to no knowledge about WiFi networks (I work solely as a firmware developer for the system), I got really curious about the fact.
The manager of the operation told me I would be able to use a tablet to connect to the network.
Why is that?
Is there any kind of WiFi network that only allows mobile devices to connect? I did not try with my phone (shame on me =/)
