#14914 I am brand new to the ESP8266 device and this seems like the same problem I am working on.

I have a set of simulators running on teensy 3.1's, that need to take commands and data from a linux process, probably a java udp server, maybe over a socket after I figure the 8266 device out. The simulators send response data back to the server so the server decides what commands to send next.

My original design was to have one controller type device talk to the linux server and then the controller talk to the simulators with some other radio, like a rfm69.

I am absolutely brand new to the esp8266 device, any suggestions would be appreciated.

#16931 I have the same problem.
I tried to run the test.ino

It fails straightaway caused by the call esp.setUart
My esp returns an error because the 00200.9.5 firmware does not know this at command.

I read in the readme that this library was made for AT .18 or .22 version.

But what is this kind of firmware? And where can I download it?
