It is much easier to develop application programs for the ESP8266 via Arduino IDE (actual version 1.6.12), than with the Espressif programming environment (SDK). That means, if you have after the first WLAN connection a data traffic pause longer than 5 minutes, you to have to resync the connection by sending some dummy characters. There is a 5 minute timeout in the ESP8266 WiFi stack. Now, in case of an Access Point change, it is no longer needed to enter manually the credentials into the ESP8266, if the WiFi Access Point supports WPS. I added to this example a WPS (WiFi Protected Setup) functionality via push button switch, named WiFiTelnetToSerialWPS.ino. There is in the Arduino ESP8266 libraries an example WiFiTelnetToSerial.ino for a Transparent UART to Telnet Server. An other software is a fork of beckdac, ESP8266-bridge, which allows to set the cedentials from the serial side via +++ commands.ģ. A promising software is esp-link, it works reliable since version 2.2.3.Ģ. So I was looking for a better solution.ġ. If your Access Point changes, it is annoying to change the credentials in the Transparent Bridge via programm change. I already used an ESP-01 module in a project as a Serial Transparent Bridge (from beckdac), see ArduinoLabPSU2#WiFi_ESP-01.

Look at for ESP8266 Serial WIFI Wireless Transceive Modul LWIP AP+STA. The main application is a Serial to WiFi Bridge, named AT. Since end of 2014 there is a very interesting WiFi module with application processor, called ESP8266, on the market, at a price of about 3 EUR.
