Which SDK version are you using, is it SDK v12.x.x? Which function returns NRF_ERROR_NO_MEM? Is it sd_ble_gatts_service_add() or sd_ble_gatts_characteristic_add()?
If it is one of those two functions then you need to increase the size of the GATT table by setting the .attr_tab_size field of ble_enable_params.gatts_enable_params in ble_stack_init(), e.g.
ble_enable_params.gatts_enable_params.attr_tab_size = 0x1000;
Otherwise if will be set equal to SOFTDEVICE_GATTS_ATTR_TAB_SIZE == BLE_GATTS_ATTR_TAB_SIZE_DEFAULT == 0x000 which causes the SoftDevice to use the default GATT table size which is 0x580 bytes for S130 v2.x.x.
