Transform your little ESP8266 into a light weight and simple to use Communcation-Over-UDP system...

Features

• Chat with other ESP8266's over UDP
• Use serial as UI for the communication with other ESP8266's (Want to know how? Type help in your serial monitor)
• Host your own custom WiFi network for communication with other ESP8266's
• Connect to existing WiFi networks for communication with other ESP8266's
• Use Port-Forwarding for communication over WAN (Internet)
• Get the current signal strength (RSSI) from the connection to your network

Installation

You can easily use the pre-compiled binary file of CHOW and just flash it onto your ESP8266, or compile it yourself with the Arduino IDE.

Installation with binary file:

1. Download the latest binary file of CHOW
2. Flash it on your ESP8266 with the baud rate of 115200. I recommend using esptool.py

esptool.py --chip esp8266 -p <port ex.: /dev/cu.usbserial-14130> -b 115200 write_flash -z 0x00000 </path/to/CHOW.bin>

3. Unplug the microcontroller. Plug it back into your computer.
4. Open the serial monitor and type the command help

Installation with Arduino IDE:

1. Download the latest arduino sketch of CHOW
2. Download the SimpleCLI Library from @spacehuhn
3. Unzip the downloaded SimpleCLI Library and rename the resulting folder to SimpleCLI
4. Paste the folder in your arduino library folder (usually located somewhere at documents/Arduino/libraries).
5. Now you can open the downloaded arduino sketch in your Arduino IDE and upload it to your ESP8266

Working on...

• Encryption for secure UDP-Packets
• Message Broadcast for sending one message to multiple microcontrollers
