- Sun May 08, 2016 3:10 pm #47133 I also purchased two of these boards on ebay.

I'm able to communicate with them using a serial converter connecting to the board. It also turns on the wifi module, as I can see it when I scan for ssids. I can't, however, connect to the built in web server. I've not tried to change any parameters using a serial connection (putty) due to a few concerning things I've read in this thread.

What I'm wanting to do is use the module with a uno board for some basic iot stuff (Blynk, etc).

I've tried various libraries, etc, but no luck getting the arduino to see the wifi shield. I've tried the suggestions within the thread, no luck.

I'm thinking I'm missing something obvious. Can anyone point me to a known-working library? I would think if its 8266 based, that would work for me, but not having any luck. Do I possibly have a config issue with the 8266 shield that would keep it from working with the Uno board?

Thanks in advance for any suggestions.

It definitely does not like being pushed to 115200, and until I can figure out the proper way to adjust the baud rate on the ESP module, I'm kind of stuck.

But I did make progress..once I figured out what was up, it was easy to get the uno talking to the shield.

- Fri May 20, 2016 9:05 pm #47744 Can you tell me what you did to get the Arduino talking to the ESP13. I am stuck. Non of the sample sketches are working.

- Sat May 21, 2016 7:59 am #47762 Can you post/paste your sketches? I'm likely not the guy to give you your answer, but I'll gladly take a look; I'm sure others on here can certainly help.

In my case, since I'm using an Uno with an esp8266 shield, I only have one hardware serial port, and then the second is a soft serial port using the digital i/o pins on the uno. I was not paying attention to what they were doing with the soft serial port and pin connections. Once I got that worked out, I was good to go.
