keil V5 compile error when I called sd_ble_gatts_sys_attr_set for NRF51822

[aileen]

When I call the function sd_ble_gatts_sys_attr_set, the compile error "source\ble.c(142): error: #165: too few arguments in function call" showed in Keil V5. But I found just 3 arguments in this fuction in nRF_Sericalization/1.1.1/application/codecs/s110/middleware/app_mw_ble_gatts.c, how to fix it?

uint32_t sd_ble_gatts_sys_attr_set(uint16_t conn_handle, uint8_t const * const p_sys_attr_data, uint16_t len)

err_code = sd_ble_gatts_sys_attr_set(m_conn_handle, NULL, 0);

You are probably using incompatible softdevice headers. The latest SDK 8.0 did not contain serialization so it doesn't support S110v8.
