Need Arduino code for enabling over-the-air (OTA) firmware updates via Bluetooth Low Energy (BLE) on an ESP32

I am looking for a freelancer who can help me with enabling over-the-air (OTA) firmware updates via Bluetooth Low Energy (BLE) on an ESP32. I do not have an existing codebase for the ESP32, so I will need someone who can create the code from scratch.

The target device for the firmware updates is ESP32. I want to connect the ESP32 through laptop blutooth and transfer the new codes. Therefore, the freelancer should have experience working with ESP32 devices and be familiar with the programming language C++.

Key requirements for this project include:
- Developing code for enabling OTA firmware updates via BLE on an ESP32
- Creating a reliable and secure communication channel between the ESP32 devices
- Implementing error handling and recovery mechanisms in case of failed firmware updates

Ideal skills and experience:
- Strong proficiency in C++ programming language
- Experience with ESP32 development and BLE communication protocols
- Knowledge of firmware update mechanisms and best practices
- Familiarity with IoT devices and embedded systems

If you have the required skills and experience, please submit your proposal for this project.
