Ota update in ESP WROOM 32 UE using arduino to ESP-IDF project

Development Tools IDE 1.x
1

hi,
I am trying to OTA update the esp32 working in ARDUINO code to ESP-IDF code. I just used the an GPRS module for downloading the bin file from the server. it receive complete data from the server successfully . I am using update.h library for OTA update. Is the arduino bootloader is compatible with esp idf version 4.4 bootloader

vPortFree(recbuff);

}

void loop()

The code uploaded below can easily change the bootloader from Arduino ide 2.0.5 to IDF VER 4.4. I am using Quectel EC200U-EU module for data downloading.
