Inhalio is a global technology company pioneering Digital Scent Technology, transforming fragrance from a passive sensory element into a smart, connected, software-controlled experience.
The problem
As Inhalio expanded across multiple markets and product lines, from personal Bluetooth devices to automotive and large-scale ambient systems, the platform faced several technical challenges:
- Supporting multiple hardware product lines with different control patterns and capabilities.
- Ensuring stable Bluetooth and IoT communication across diverse environments.
- Designing a scalable backend architecture capable of handling device data, user behavior, and future analytics.
- Delivering a seamless end-to-end user experience, from device onboarding to scent scheduling and cartridge management.
- Maintaining clear integration boundaries between firmware, mobile apps, and cloud services to support long-term scalability.
What we built
CoderPush worked closely with Inhalio to design and implement a robust, modular software architecture spanning device, mobile, and backend layers.
Key contributions included:
- System-level software design: Defined the overall architecture connecting embedded firmware, mobile applications, and cloud services.
- Embedded & BLE communication design: Designed Bluetooth Low Energy (BLE) connection patterns supporting pairing, session handling, and command abstraction across multiple device types.
- Mobile application development support: Implemented core user flows such as device onboarding, setup, and cartridge recognition to ensure a smooth, intuitive experience.
- Backend architecture & API design: Built scalable APIs to manage users, devices, cartridge metadata, and future platform expansion.
- Clear integration boundaries: Established well-defined interfaces between firmware, app, and backend teams to enable faster iteration and parallel development.
This approach allowed Inhalio to maintain consistency while scaling across products such as Aromini BT, AromaDream, Ambience, and automotive scent systems.
