Arduino ESP8266 tcp server receives gibberish

[HarryJenkins]

Hi,

I'm trying to set up a wireless TCP server, using an Elegoo Arduino Uno (equivalent to the SparkFun RedBoard) and a SparkFun ESP8266 shield. I pieced together the code from the examples that came with the ESP8266 and some other stuff I found on the Web (danger, Will Robinson!). It mostly works, except for the really important part.
