andrewboyson 0:09f915e6f9f6 27 ==========
andrewboyson 0:09f915e6f9f6 28 Raw character talking to the ESP 8266.
andrewboyson 3:accba7e07a0d 29 Sends strings and data to the ESP.
andrewboyson 0:09f915e6f9f6 30 Receives characters from the ESP and treats the following cases:
andrewboyson 0:09f915e6f9f6 31 '\n' -> sends a completed line
andrewboyson 0:09f915e6f9f6 32 '+IPD,id,len:' -> reads in length bytes to the relevant id's input buffer
andrewboyson 0:09f915e6f9f6 33 '>' -> sends the data to the id specified
andrewboyson 0:09f915e6f9f6 34 otherwise -> adds to the current line
