idf.py menuconfig

• Under Component config -> esptic2udp, set the following:
  • UART for receiving TIC frames and TIC baudrate
  • GPIO number for LED heartbeat and LED active state
  • Target UDP host and port
• Under Component config -> simple_network, configure as needed
• Under Component config -> tic2json, set TIC version and adjust options as needed
• Under Component config - > Common ESP-related, it is advised to move the console IO to a different UART than the one used by this app

Build the project and flash it to the board:

idf.py flash

See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.

Tested working on ESP8266 and ESP32.

Use e.g. TIC2UART to connect the TIC output of the meter to the RX pin of your ESP board.
