Sourcing Requirements
Smart Ring Hrv Bluetooth I am interested in your smart ring product and would like to ask a few technical questions to; understand the data capabilities; 1. Can the ring export raw data such as heart rate, sleep data, activity data, HRV, and; temperature? If yes, in which formats (CSV, JSON, or others)?; 2. Does the device require a cloud account to access the data, or can all data be stored; and exported locally without using your cloud service?; 3. Do you provide an SDK or API for developers? If yes, could you please share the; documentation or an example of the API/SDK reference?; 4. In your product description, what exactly does “open source” refer to? Is the firmware; open source, or does it mean that the communication protocol or SDK is available?; 5. Does the ring support local Bluetooth Low Energy (BLE) communication so I can; read the sensor data directly with my own application?; 6. Can you provide a single sample unit for testing these features before placing a bulk; order? If so, what is the price and lead time?; 7. Can the device work with a custom application, or is it restricted to your own app?; 8. At what frequency is raw data recorded (for example, heart rate per second, per; minute, or continuous), and can full-resolution sensor data be exported?.
