The firmwares in firmwares use the esp-open-sdk. You may need to customize the main.c files to reflect your WiFi configuration. This is mainly a hardware project and not a software project, so the firmwares are primarily meant to be demos for the hardware features of the watch. Firmwares can be uploaded using esptool and debugging is possible with a serial port terminal like espterm.
