What is OTA programming in ESP32? The OTA programming allows updating/uploading a new program to ESP32 using Wi-Fi instead of requiring the user to connect the ESP32 to a computer via USB to perform the update. OTA functionality is extremely useful in case of no physical access to the ESP module. It helps reduce the amount of time spent for updating each ESP module at the time of maintenance.
This firmware allows not only to have a cheap bridge between Wifi and serial, but also to have a web UI to configure wifi, to monitor 3D printer and even control it, and to make things easy, UI is fully customizable without reflashing FW.
Note: Using the Sigfox radio without the external antenna can lead to damage of the device and is therefore not recommended. Please note: Pycom modules are powered by the new and feature-packed Espressif ESP32 chip. As a result, the firmware is evolving constantly as the ESP32 IDF matures. Regular firmware updates are therefore provided.
