How to get the service handle using only the attribute handle

[AGhar]

Hi dears,

I am using the BlueNRG-MS library.

I want to update my characteristic before allow the client to read it.

However to use BTSi_UpdateChar I need both the char handle and the service handle, and the callback event only provide me with the char handle.

I looked well in the library documentation and there were no API to provide such.

Thanks in advance
