| Jun 17, 2016 at 20:13 | comment | added | Snr Srub | Hi, sorry for taking so long to reply, I haven't looked on here in a while. If it's still helpful to say, I didn't change the header file, I use the setBaud function from SparkFunESP8266WiFi.h straight after using begin() | |
| Jun 6, 2016 at 19:23 | comment | added | James T | It looks like I have the same problem. I used the "ESP8266_Shield_Demo_Sparkfun" and often the webpage shows not a proper output ("AT.." commands instead). How did you adapt the baud rate in the "SparkFunESP8266WiFi.h"? Thanks! | |

| Mar 5, 2016 at 18:59 | comment | added | Snr Srub | @JRobert I've checked communication on Wireshark and it looks OK. Every time the client refreshes the webpage it should send a message to the ESP8266 that should be picked up by client.read() I think the problem lies in getting the frame from the ESP8266 to the Arduino, as the system is successfully sending the webpage as requested. | |
| Mar 5, 2016 at 16:54 | comment | added | JRobert | You're welcome. I wasn't convinced that was it, but now it's one less possibility! So now you know that coming out of the while loop, clientline contains two characters, one of which is some kind of whitespace, likely a space, and a '\n' (because the terminal line-feeds). You may need to be debugging the client at this point. Are you sure it is sending what you think it should be? | |
| Mar 5, 2016 at 15:53 | comment | added | Snr Srub | Hi @JRobert, thanks for the advice. I've made those changes, but the serial output is still the same. | |

At for( int i = 0; i <= index; i++), I don't believe you've initialized clientline[index] anywhere, so the final iteration will print an undefined character. I don't know if this is the error, but I think it is an error. You could instead set clientline[index] = 0円; (i.e. NUL-terminate the line), and replace the for-loop with Serial.print(clientline);, letting Serial.print() print the whole string for you.
