我正在尝试从这个小传感器https://www.aliexpress.com/item/temperature-sensor-and-humidity-sensor-HTS221/32953862359.html?spm=a2g0s.9042311.0.0.e3534c4dT9GRz3读取温度
There are 4 GattServices available
GattService 00001800-0000-1000-8000-00805f9b34fb - Generic Access
here are characteristics:
00002a00-0000-1000-8000-00805f9b34fb Device Name
00002a01-0000-1000-8000-00805f9b34fb Appearance

no characteristics
GattService 0000180a-0000-1000-8000-00805f9b34fb - Device Information
here is characteristic:

GattService 6e400000-b5a3-f393-e0a9-e50e24dcca9e - ???
看起来HTS221默认没有发送数据，我应该怎么做才能读取温度？
