Hello guys! I’m very new to the IoT world, and I decided to buy an ESP32 LoRa V3. I cleared the Heltec firmware and installed MicroPython. How can I roll back to the factory firmware?
How to Restore Factory Firmware on ESP32 LoRa V3?
The above link is the official codebase where this example is available. The library can be used at this link: Heltec ESP32 Series Quick Start — esp32 latest documentation
But I don’t think it makes sense for you to roll back to it, which is only used to test the basic functionality of the device, and has no specific purpose.
The thing about Arduino/C++ is that you can flash just any sketch to ‘roll back’ - you don’t need the factory firmware.
To switch to MicroPython you must indeed flash the MicroPython interpreter / environment, but to go back you don’t need to do anything but upload whatever you want to upload from Arduino / PlatformIO / whatever. That automatically erases the MicroPython environment.
