Custom Software Development

Since 2006, Soft Service Company has specialized in developing software for wireless technologies. We create reliable solutions for Bluetooth, Wi-Fi, and serial communication, as well as embedded firmware for IoT devices. Our experience covers a wide range of tasks: from simple utilities to complex distributed systems.

Bluetooth

• Application development for Bluetooth Classic and Bluetooth Low Energy (BLE).
• GATT client and server implementation, working with profiles (OBEX, OPP, FTP, RFCOMM).
• Integration with audio devices, volume control and switching.
• Support for non-standard drivers (BlueSoleil, Toshiba) and USB dongles (BLED112).
• Working with BLE beacons, receiving and decoding advertisement packets.

Wi-Fi

• Development of applications for native Wi-Fi and Wi-Fi Direct.
• Creation of access points (SoftAP, Hosted Network), black/white list management.
• Raw Wi-Fi packet capture and analysis (sniffing).
• Network adapter management, reading and changing IP settings.
• Integration with Windows Network List Manager.

Serial Communication

• Working with COM ports, UART, RS232 on Windows and macOS.
• Development of drivers and applications for data exchange with peripheral devices.
• Support for USB virtual COM ports, modems, Bluetooth vCOM.

IoT Firmware (Arduino, ESP32)

• Development and debugging of firmware for Arduino, ESP32, ESP8266.
• Programming sensors, actuators, displays, communication modules.
• Integration with cloud platforms (MQTT, HTTP, WebSockets).
• Creating OTA updates and energy-efficient solutions.

We have completed projects for automation of residential and commercial spaces, including:

• Control of lighting, climate, and curtains.
• Integration with voice assistants (Google Assistant, Amazon Alexa, Yandex Alice, Apple Siri).
• Sensor monitoring (temperature, humidity, motion, door/window opening).
• Development of custom controllers and hubs based on ESP32/Arduino.
• Mobile and desktop applications for smart home management.

• 20+ years of experience in wireless solution development.
• Our own libraries (Wireless Communication Library) — a proven code base.
• Full cycle: from idea and design to implementation and support.
• Flexible cooperation models: fixed price, hourly rate, outsourcing.
• Confidentiality and transfer of all rights to the developed software.

1. Discussion — you describe the problem, we propose solution options.
2. Estimation and plan — we agree on timelines, cost, and stages.
3. Development — we create a prototype, then a full-featured solution.
4. Testing — we verify on real devices and in different environments.
5. Support — we provide updates and improvements after launch.
