How to use

• Flash the firmware to esp8266
• Connect esp8266 rx/tx/gnd pins to the remote device
• Connect to esp8266 wifi access point named esp8266-XXXXXX and and set it up
• Use socat on local linux machine to create a virtual tty that is connected to esp8266

socat command example below, replace ESP-IP

socat pty,link=/dev/virtual0 tcp:ESP-IP:2217

TODO

• Configurable port, for now it is hardcoded to 2217 in config.hpp
• Configurable baudrate, for now it is hardcoded to 115200 in config.hpp
