But it would be easy to extend, to read and write to any RS232 device, and then say send the results over wi-fi.

This code just reads whatever it gets on the RS232 port, and prints it to the USB serial port.
#ESP8266 SERIAL PORT WIFI HOW TO#
Accept incomming connections and transmit/receive raw serial data using the TX/RX on the ESP8266 without any other control information in it. Skeleton code to show how to communicate from a Huzzah Feather ESP8266 to an RS232 port using a MAX3232 Board. Connect as a client to my wifi access point "Wireless" The client can make HTTP GET requests to the server to. So, it can connect to the ESP8266 server wireless network.

You can also configure a fixed IP address in Arduino. So, other Wi-Fi devices can connect to that network ( SSID: ESP8266-Access-Point, Password: 123456789). Bittle will print out the IP address assigned by DHCP through the serial port after connecting to the WiFi successfully.
#ESP8266 SERIAL PORT WIFI SOFTWARE#
Then it sends every received line of data trough software serial port to ESP8266. Arduino listens for serial port communication on its hardware serial port. So in short, I need to create custom firmware to perform the following: The ESP8266 server creates its own wireless network ( ESP8266 Soft-Access Point ). This tutorial shows how to connect Arduino to the TX line (of a router, RPI) and display serial data on smartphone over WiFi. I am trying to figure out how to make custom firmware that will not require any AT commands to perform the serial bridging functions so that the application on my computer can connect directly to the physical serial port of the device but that the actual serial data would be transmitted and received over a wifi connection that was established by the ESP8266. I have an application which would normally connect to the physical serial port of a device.
