I am looking to develop a small, portable hardware device based on the ESP32 platform. This device will function as a Bluetooth headset receiver enabling connection with a phone, and will also have a 3.5mm output for connecting to headphones with a microphone. Key Features: - Dual functionality: Hands-free calling and audio recording. - Basic audio quality: The device does not require high-end audio processing capabilities. - Up to 4 hours of battery life: The device should be powered by a compact battery pack, delivering sufficient power for short trips or commutes. The device will communicate with a mobile application to receive instructions for recording. It should be capable of detecting phone calls and recording them automatically. After each call, there needs to be a mechanism for transferring the audio files to the app, with filenames incorporating the phone number and timestamp if possible. Skills and Experience: - Proficient in hardware development, particularly with the ESP32 platform. - Prior experience with Bluetooth technology and headset design. - Knowledge in portable battery-powered device design. - Familiarity with mobile app integration for hardware devices. This project is perfect for someone with a knack for creating compact, functional hardware, who can deliver a device that meets these specifications. Eventually I will also need a way to mass produce this device, build an eclosure.

As an experienced Electrical/Electronics Engineer, I have spent over 8 years honing my skills in PCB Design using platforms such as Eagle, Altium, KiCAD and EasyEDA. My expertise also extends significantly into CAD/Housing design, which would be particularly useful when it comes to encasing your device for mass production. Additionally, I'm capable of proficiently working with tools like MATLAB/SIMULINK and Python, which can be extremely handy during the project's development stages. Understanding that this device needs to be small and portable with a short battery life, necessitates having an engineer who understands the intricacies of power optimization. Luckily for you, I have extensive knowledge in developing battery-powered portable devices and I've even worked appreciably with ESP32 in the past. Bluetooth technology and headset design aren't new concepts to me either. Lastly, my familiarity with app integration for hardware devices makes me well-equipped to provide you with a seamless interaction between your device and your mobile application. Consequently, each call will automatically be recorded and transferred to the app with filenames perfectly organized with phone numbers and timestamps. Let's discuss further details – people usually consider my service their one-stop solution shop!
