如何添加属性?

Dears,

如何添加属性?

For example, want to send after adding characteristics uuid under HRPS service uuid.

That is, indication, notification, rd, wr are added to below HRPS uuid 0x180D and 0x2a37, 0x2a38, 0x2a39 are used for uuid.
This time, after arbitrary value, 0x2a90 is input and check with BLE utility Smartphone App, can’t find attribute under HRPS uuid.
By the way, changing from 0x2a38 to 0x2a90, which is already defined value and check with BLE utility Smartphone App, we can find out that 0x2a38 is changed to 0x2a90 under HRPS uuid.
It means that attribute defined in DA14580 SDK code can be changed but adding new ones is impossible. Let me know if I missed something.

Lastly, is it problem if input 2 notification attributes under 1 service?

Thx.
Jeffrey
