Software for a ESP8266 based walkie talkie radio (doesn't work very well)
This is a somewhat failed attempt to make a ESP8266 based two-way radio. It fails due to ESP8266 causing a lot of radio noise in the audio signals.
To build the firmware, you need https://github.com/SuperHouse/esp-open-rtos and https://github.com/pfalcon/esp-open-sdk/ installed.
Make sure that esp-open-sdk is in your PATH environment variable.
If needed, edit ESP_OPEN_RTOS_DIR in Makefile.
Then just type make
to build or make flash
to also program the ESP8266.
See http://essentialscrap.com/esptalkie/ for more details, but for basic testing you can connect:
There is a script in tools/listen.py that can act as the other end of the connection, playing back sound using PC speakers.
