ESP32 Firmware Development for Custom PCB

Very easy project for me. Have done 100s of industrial applications with ESP32 hardware and firmware. Expert in GSM , OLED interfaces to EAP32. Can finish the firmware in a week.

Hello, I understand that you need an experienced firmware engineer to develop firmware for your custom PCB with an ESP32 MCU. My approach will focus on creating the firmware to manage basic I/O operations, control the OLED display, and implement menu navigation. I’m well-versed in GSM communication, so I can ensure effective SMS handling and compatibility with your hardware peripherals like buttons and SIM modules. Comprehensive documentation and a compiled binary/hex file will be provided for easy upload during assembly. Could you provide details about the specific functionalities you want for the GSM communication, particularly for SMS handling? Thanks, Muhammad Awais

Hi there Matthew B., I'm bidding on your project "ESP32 Firmware Development for Custom PCB". Let's dive in and have a meeting I am expert in this area. please leave a message on my chat so we can discuss the budget and deadline of the project. I have read your project description and i'm confident i can do this project for you perfectly. Regards, Usama ..

Since 2003 I am working in Digital Electronic. So more than 18 years of experience in Electronics. Arduino NANO/UNO/MEGA, ESP32 and Raspberry PI to build a digital device to read sensor data and send it to the web server, motor control, control relay switches and LEDs. More than 5(five) years of experience in Arduino design and build. If you want an excellent and error-free project delivery, then send a message to me, please. Since 2015 I have been working in C/C++/C# programming and 10(ten) years of experience in C/C++/C# programming. Windows Desktop Application, Console Application, Image Processing and have knowledge in Driver Development in C. Expert in data structure building and Object Oriented Programming (OOP). Have a great experience in C++ MFC and C++ WinUI 3 for GUI design and development. Also expert in C/C++ GPU CUDA programming. If you want a good delivery of the project, then send me a message, please.

Hello! I will make ESP32 Firmware for you. Kindly come over chat and plan the project for the same............................

I have solid experience with ESP32 firmware development, GSM communication, and display control. I can write efficient firmware to handle I/O operations, menu navigation, and SMS functions while ensuring seamless hardware integration. Don’t pay or award me the project until I send you a sample confirming your requirements. Let’s get started!

Hi, This project sounds really exciting, and I’d love to help! I have strong experience in embedded systems and ESP32 development, and what’s even better—I’m very comfortable working remotely. I’ve successfully handled multiple embedded projects from afar, using remote debugging tools, cloud-based development environments, and VPN access for secure collaboration. Why I’m a Great Fit: ? ESP32 Firmware Development – I’ll take care of I/O operations, button inputs, OLED display control, and menu navigation. ? GSM Communication – I’ve worked with GSM modules before, so handling SMS and SIM integration will be smooth. ? Remote-Friendly Workflow – I’m used to working with J-Link, OpenOCD, VS Code Remote, and cloud debugging setups, making remote firmware development seamless. ? Easy-to-Update Code – I’ll deliver clean, well-documented firmware with a compiled binary/hex file, so future updates are hassle-free. I love working on embedded projects and making remote collaboration easy. Let’s chat and get this rolling! Looking forward to working together. Best, Bachana

Hello, I can professionally handle the firmware development process required for your ESP32-based custom PCB project. I have extensive experience in embedded systems, hardware integration, and GSM communication—particularly SMS protocols. In previous projects, I have successfully implemented user interfaces including button control, OLED display management, and menu navigation. With strong proficiency in C/C++ programming and experience in delivering production-ready binary/hex files, I can contribute to your project efficiently and reliably. Additionally, I will provide comprehensive documentation to support future firmware updates and ensure long-term maintainability.
