ESP32 Master update firmware to ESP32 Slave by using .bin file in SPIFFS

[tienpm]

Hi everyone, I have 2 ESP32 , ESP32 1 is master and ESP32 2 is slave. I want to let the ESP32 master use .bin file in SPIFFS to update firmware for the ESP32 slave (may be via serial). If anyone has sample code for this, please let me know. Thank you very much.
