android - 需要从脉搏血氧计读取 Spo2 和 PRbpm

Question

这是我找到的 JSON。服务 UUID 是:636F6D2E-6A69-7561-6E2E-504F56313100 特征 UUID 是:7274782E-6A69-7561-6E2E-504F56313100 用于从血氧计读取数据，我只有这两个东西，但我不知道我需要发送什么 Hex 来检索 SpO2 和 PRbpm。

ihealthlabs SDK 和文档可在此处获得 https://github.com/iHealthDeviceLabs/iHealthDeviceLabs-Android .并且还提供了免费的示例项目，您可以使用它从其文档中提供的支持列表中检索数据(SpO2 和 PRbpm)
