    Hello Sony,
    You can start by reviewing how simple_central read the characteristics in simple_peripheral.
    After the connection is formed in case GAP_LINK_ESTABLISHED_EVENT startDiscClock is started that will post the event
    SBC_START_DISCOVERY_EVT and which in turn will start the characteristic discovery (SimpleBLECentral_startDiscovery).

    The discovery process can be reviewed in SimpleBLECentral_processGATTDiscEvent. You can implement read/write directly here after the desired characteristic handle is obtained.

    Then review the case GATT_RW: in SimpleBLECentral_handleKeys to see how to read/write from/to charHdl.
