Are two boards capable of communicating with each other? If so, how would I go about connecting the two boards together?
My goal is to record sensor data on one board and send the data over a long distance to another board that will then produce a response.

Here is a link that describes the modes the 8266 can use for communication. https://github.com/esp8266/Arduino/tree ... sp8266wifi

Re: Feather Huzzah ESP8266 Communication
Thank you.
After reading through the information, it seems like you can only connect the ESP8266 to a computer/phone. Has anyone had any luck connecting it to a second ESP8266?
We are trying to create a device that takes sensor information from one user and transmits the information to a second user in a remote location. Is this is a possibility?
Thanks for the help!

You can program one ESP8266 to run as a Wifi access point and have the other one connect to that. The WAP can talk to devices through TCP/IP while it's also handling the Wifi connection.

Thank you!
Will this work across long distances? Or is this short ranged?

It's a Wifi connection, so the nominal range is about 50m. That tends to be a best-case estimate even for consumer Wifi hubs, but I'd guess you could make a connection work at 20m to 30m in an environment without a lot of other Wifi interference.
