* IRremoteESP8266: IRGCTCPServer - send Global Cache-formatted codes via TCP.
|
|
* An IR emitter must be connected to GPIO pin 4.

* Example command - Samsung TV power toggle: 38000,1,1,170,170,20,63,20,63,20,63,20,20,20,20,20,20,20,20,20,20,20,63,20,63,20,63,20,20,20,20,20,20,20,20,20,20,20,20,20,63,20,20,20,20,20,20,20,20,20,20,20,20,20,63,20,20,20,63,20,63,20,63,20,63,20,63,20,63,20,1798\r\n

|
|
*
|
|
* How to use this program:
|
|
* 1) Update "kSsid" and "kPassword" below for your WIFI network.
|
|
* 2) Compile and upload the sketch to your ESP8266 module.
|
|
* 3) (Optional) Use the serial connection to confirm it started and get the
|
|
* IP address.
|
|
* 4) From a client machine, connect to port 4998 on the ESP8266, using
|
|
* 'telnet', 'nc' (netcat), 'putty' or similar command, etc.
|
|
* You may need to install one.
|
|
* Unix/OSX:
|
|
* Start a shell. Then type:
|
|
* telnet <esp8266deviceIPaddress> 4998
|
|
* Windows:
|
|
* Start a new CMD window, then type:
|
|
* telnet <esp8266deviceIPaddress> 4998
|
|
*
|
|
* 5) Enter a Global Cache-formatted code, starting at the frequency,
|
|
* and then a return/enter at the end. No spaces. e.g.:
|
|
*
|
|
* 38000,1,1,170,170,20,63,20,63,20,63,20,20,20,20,20,20,20,20,20,20,20,63,20,63,20,63,20,20,20,20,20,20,20,20,20,20,20,20,20,63,20,20,20,20,20,20,20,20,20,20,20,20,20,63,20,20,20,63,20,63,20,63,20,63,20,63,20,63,20,1798
|
|
*
|
|
* To exit the 'telnet' command:
|
|
* press <control> + <]> at the same time, then press 'q', and then <return>.
|
|
* or:
|
|
* <control> + <d> might work.
|
|
*
|
|
* This program will display the ESP's IP address on the serial console, or you
|
|
* can check your wifi router for it's address.
