Allow more than one connection in WiFiSPIServer #14

Open JiriBilek opened 5 years ago

JiriBilek commented 5 years ago

The WiFiSPIServer class allows only one incoming connection, although ESP8266 has no such limitation (in fact, there is obviously an limitation but is higher than one) . The limit is forced by the _sock array that serves as binding information between master and slave. Discussed in #13

Strange, many internet sources say the ESP8266 can make 4 (or 5) connections at a time. I have just tested 32 concurrent TCPIP connections coming from 3 distinct IP addresses (not having more computers here).

I have read 8 maximum concurrent, but also that this is configurable :-)

I did more tests - 16 concurrent clients running fine. https://gist.github.com/JiriBilek/7bdde1863a3340ad58cbebbcc080583e
