I have one Arduino and I want to control a Servo motor and other devices. The Servo motor is further away from the Arduino so I want to control it wirelessly. The problem is that I want the Servo to communicate to the Arduino, which in turn communicates to me via wifi, text message, website, etc. I'm guessing I would need two esp8266 chips, one connected to the Servo and one connected to the Arduino. I would also like the other devices to communicate to be via wifi, text message, website as well which are connected to the arduino wired.
Yes, I agree with @Paulo Soares to use 2 Arduinos.
It makes little sense to make the 2nd wireless jump between the 2 Arduinos using a complex packet protocol such as TCP/IP. This project uses 2 Xbee radios. I suspect it is also possible to accomplish this using COTS model airplane radio. This may be talked about here but it is not clear if the hardware talks to existing R/C hardware or to proprietary hardware.
