I have ESP32 and SIM800L module. I want to take a image and send it over MQTT. Because of this, I have this code:

GPT4 said that It might be caused by the pin selection which mine is 14 15. I tried with 13 14 via SoftwareSerial it didnt worked again. Other forums have the same question with different problems which is not answering my problem. So, I am out of ideas. Any idea might be useful.Guru Meditation Error: Core 1 panic'ed (LoadProhibited).
