How to Perform Firmware Update on ESP32 Using T-SIM7600X

[rajmehta28599]

I am looking for a detailed guide on how to update the firmware of an ESP32 microcontroller using a T-SIM7600X module. Specifically, I need information on:

1. Required hardware and software tools for the firmware update process.
2. Steps to configure the T-SIM7600X for use with the ESP32.
3. Methods to upload the firmware to the ESP32 via the T-SIM7600X module.
4. Troubleshooting common issues encountered during the firmware update.
5. Best practices for ensuring a smooth and secure firmware update process.

Any examples, code snippets, or links to comprehensive tutorials would be greatly appreciated.

i don't understand you whant the defautl code or a new code? firmware in a microcotroler its like a program, and usually you said firmware for back code

I hope you're familiar with the ESP32 OTA update feature, which allows for OTA updates over Wi-Fi.

That same thing I want to perform using T-SIM7600X. without ESP32 Wi-Fi.

I appreciate your response.

Thank you

I understand the process, but initially, you must work with AT commands to download data from a server, then copy the information to EEPROM, followed by an OTA update. I’m uncertain if the available RAM will suffice for the data download. If time permits, this project seems intriguing.
