We are seeking a reliable OEM/ODM partner for our smart wearable project. Our primary focus is on developing a smart band (without display) and a smart ring that can efficiently capture raw analog signal data from sensors. These devices should be capable of interfacing with a mobile app via Bluetooth, enabling seamless data transmission for user analysis. Additionally, we would appreciate solutions that include an open-source SDK, allowing us to customize the firmware to align with our specific requirements. We are particularly interested in flexibility and scalability in your offerings, as these features are essential for our product development. Please share your capabilities and any relevant experience in this domain.
