I think the HC-10 uses BT4.0, or BLE? You need the BLE extension to connect.
Look here for an example: http://appinventor.mit.edu/explore/blogs/karen/2016/08/heart.html or in the BLE section of the FAQ in this forum.

Yes!¡!  is BLE ... and have to do it on arduino nano one or mega... 

so

#include <CurieBle.h>
BLEPeripheral blePeripheral; 

the mobil android is the client and the arduino bluetooth play like role=0 

I m confuse it .

Read the article in mentioned in the link I gave you. The article is here: http://ai2.appinventor.mit.edu/reference/other/IoT.html
The example uses an Arduino 101, which has BLE built-in, but with your HC-10 it should work the same.

The BLE extension for App Inventor can be found here: http://appinventor.mit.edu/extensions/
but you could also take the heart-rate monitor .aia from the example and change it for your purpose.

As for the Client-Server role: usually the phone is the client. It sends a request to the Arduino (server) which serves (returns) the data requested.
It is very similar to what happens on the web: a client, phone or webbrowser sends a request to a server somewhere on the web, and the server sends data back, wich the browser or the phone can display.
