Feature Request: Enable ESP32 Firmware Upgrade via SIM7000G

Overview:
The LilyGO board, integrating ESP32 with SIM7000G, presents a powerful solution for Internet of Things (IoT) projects. However, one key aspect that could enhance its usability is enabling firmware upgrades directly through the SIM7000G module. Currently, users rely on Wi-Fi for Over-The-Air (OTA) updates, which can pose limitations, especially in scenarios where Wi-Fi connectivity isn't available or reliable.

Key Features:

1. SIM7000G Integration:

2. OTA Update Mechanism: Develop a robust Over-The-Air (OTA) update mechanism that utilizes the SIM7000G module to transfer firmware updates securely and efficiently.

3. Configuration Flexibility: Provide users with options to configure firmware upgrade settings through the SIM7000G module, such as frequency of update checks, update file storage location, and update scheduling.

4. Error Handling and Recovery: Implement comprehensive error handling mechanisms to manage interruptions during the firmware upgrade process, ensuring seamless recovery and minimal disruption to device functionality.

5. Security Considerations: Prioritize security measures to protect firmware updates from unauthorized access or tampering during transmission over the cellular network.

6. Documentation and Support: Offer clear and detailed documentation, including step-by-step guides and troubleshooting resources, to assist users in utilizing the SIM7000G module for ESP32 firmware upgrades effectively.
