Try something like this:

Char data[100];
uint16_t Length = Sizeof(data);
For (uint16_t I=0, I<100, I++)
{
  Data[i] = timestamp_data;
}
Ble_nus_data_send(&m_nus, &data, &Length, m_conn_handle);

I can't really help further

i don't understand your code . please explain for my content above code

Yes; I just posted this elsewhere and it might be helpful; note your "size of (data)" is an address of a variable containing the number of bytes - see the Nordic code describing ble_nus_data_send() for more details:

uint32_t StoredPacketTransmit(BlePacketFormat_t *pPacketToTransmit, uint16_t PacketLength)
{
    uint32_t err_code = SOMETHING_BAD;
    // Define the structure to identify the Nordic UART Service
    ble_nus_t * p_m_nus = get_mNUS();
    if (pPacketToTransmit && PacketLength && p_m_nus)
    {
        err_code = ble_nus_data_send(p_m_nus, pPacketToTransmit, &PacketLength);
        if (err_code == NRF_SUCCESS)
        {
            // Packet sent, allow next packet to be built when sufficent SAADC samples available
        }
        else
        {
            // Packet not sent, next packet build is disallowed until current packet is sent
            mDelayedPacketCount++;
        }
    }
    // Allow caller to see if packet actually went out
    return err_code;
}
