The events are usually received in ble_evt_dispatch(). And they are usually forwarded to for example on_ble_central_evt(). If there isn't a case for BLE_GATTC_EVT_READ_RSP, you can add one.

Are You sure that I will receive this event in ble_evt_dispatch()??? Possible I'll receive same event in

void on_ble_central_evt(ble_evt_t * p_ble_evt)

Second there is no in SDK13 define BLE_GATTC_EVT_READ_RSP.

You can get it from the SoftDevice, in ble_evt_dispatch(). It is usually handled like this:

switch (p_ble_evt->header.evt_id)
{
    case BLE_GATTC_EVT_READ_RSP:
        
        break;
    default:
        // No implementation needed.
        break;
}

Thanks. Where can I get a BLE_GATTC_EVT_READ_RSP event? I don't have in my project this define.

Have you tried sd_ble_gattc_read(uint16_t conn_handle, uint16_t handle, uint16_t offset)?

sd_ble_gattc_read(0x0000, 0x0012, 0x0000);

Then you should get a BLE_GATTC_EVT_READ_RSP event with the characteristic value.

See this for MSC.
