what's the value of PARAMETER_SIZE_IN_BYTES ?
that is: 32
I found something new. The idea is this:
- connect to the servers hotspot
- Send your MAC address to the hotspot
- Receive the network name and password
- Send the last chars of both the network name and password
- If a match with data from the hotspot, send back "OKE"
But when I use a program called Packet Sender to send the data.
You can see that is works. But after I get the network name and password
and I send the last chars of both, the ESP crashes.
But if I just send the last chars of both, without doing the others steps, it works fine, see pic below:
