I have attached the changes.txt file, follow the instructions mentioned in it to make the respective changes in ESP-IDF. All the details like dir, file name, line number and changes to be made are mentioned in the file.

I have implemented AT+XAPL command. But for this you have to make changes to the ESP32 IDF framework and add functions implementing APPLE command. There is no direct function available that can be used to send custom AT commands.
