產品是不是正常是根據產品的spec定的。但是根據血氧的測量原理，血氧是可以獨立測試。

As the smartwatch measures the blood oxygen level, red light reflected off the subcutaneous tissue or bone is projected onto the body surface. The light is reflected from the subcutaneous tissue or bone and presented to the smartwatch's sensor, which determines the difference between the reflected and emitted light

• 沒錯，軟件裏麵的邏輯出了問題，一個更新就解決的問題。 -dakinglaile- ♂ (0 bytes) () 09/12/2023 postreply 18:39:42
