ESP8266 Community Forum

- Sun Dec 27, 2015 2:52 pm #37262 Hi guys, I am a newbie with ESP8266 and having a lot of difficulty with it. I bought 2 ESP8266 to add to two of my Arduino Uno projects so that I could get WIFI capabilities rather than getting an ethernet / wifi shield.

I am demoing on an empty board to get it working then the aim is to add the working code to my existing projects so that I can send and receive MQTT messages but have a hit a massive roadblock and running out of time I have to have the prototypes working in the next couple of days and do not have enough time to purchase a shield as the delivery will not get here in time.

So far I have failed with all online examples of getting connected to my network but if I upload blank sketch and send AT+RST via serial monitor it appears to be working ok as far as I can see.

Code: Select allAT+RST


OK

However when I try any of the sketches I cannot connect to my network, please can someone offer assistance.

Thanks in advance.

- Tue Dec 29, 2015 12:17 am #37362 What did you do? I'm exactly trying to get an existing project to work with the ESP8266. I can send AT commands when I upload a blank sketch, but if I upload something else I get no response. What was your next step to solve it? Thanks.
