Can the ESP32 in the test circuit hold the firmware and upload it to the main circuit’s ESP32
To upload firmware from one ESP32 to another using UART:
- Connect the ESP32s (TX to RX, RX to TX)
- Use a tool or library to send the firmware binary:
- ESP-IDF:
esptool command-line tool
- Arduino IDE: "Upload using a Programmer" feature, select "ESP32 UART"
- Ensure the receiving ESP32 is in bootloader mode
This should work fine5 replies
