That link leads to several possibilities, so still not sure what to do. However, upgraded to the another firmware and I'm now able to connect to wifi, but still not able to create a node.

Using this firmware:
00200.9.5(b1)
compiled @ Dec 25 2014 21:40:28
AI-THINKER Dec 25 2014

Getting this information from serial:
Response timeout
hwReset
E_CWMODE
Send cmd:AT+CWMODE=1

Any ideas?

Check the serial speed. I changed mine from 115200 to 9600 and had good results. (in the arduino example)

Also do you have any other nodes added to the server? If so I would make sure that the child id in the arduino program is not the same as any others.
Look for #define CHILD_ID_******* and change the number to something different than other sensors. I only had two sensors on when I had issues so I numbered them 3 and 4. After that the server added N0S3 and N0S4.

I have run into this and it will not add the sensor, it will show that the server is getting the signla in debug though.

Response timeout can also mean that Arduino did not receive response from ESP8266. Is wiring correct?

This link is to firmware:
drive.google.com/folderview?id=0B_ctPy0p...vSkJmNU0&usp=sharing

and select 0.952 support Smartlink. I will prepare tutorial, because it's big mess with firmware versions. It's very important to use correct firmware or EasyIoTESP8266 lib will not work correctly.

I will experiment with various serial speeds.
I have no other nodes, trying to get my first node up.

I will check my wiring again. I will check that link for firmware
