How to receive and transfer data using custom ble service

Sorry - that wasn't clear.

Steps 6 & 7 of that tutorial describe how to handle stuff coming from the Central;

Step 8 describes sending stuff coming to the Central.

The whole point of BLE is to transfer data between Peripheral & Central - so all of the SDK BLE examples illustrate that in one form or another:

For transferring arbitrary data, take a look at the Nordic UART Service (NUS) - which is, in itself, an example of how to do custom services & characteristics:

Note that none of this is specific to the Central being Android.

I am not asking about the android app development. I am asking about how can I send or receive data through ble connection. I just want an example code.

Android app development is outside the scope of this forum - you will need to study the Android developer documentation, and visit Android developer forums

There are some examples in the Nordic GitHub:
