Cordio BLE not supporting max/min connection event length

Hi!,
i tried to make some experiments with my artemis thing board plus boards from sparkfun for measuring the maximum troughput from a central and a peripheral device implemented using cordio stack with WDXC_ENABLED/WDXS_ENABLED, and i found that the min/max connection event lenght parameters specified in the connection specification type struct (corresponding to minCELen/maxCELen in hciConnSpec_t, respectively) are not taking into consideration neither in the connection creation nor the connection parameters update, so only one packet is sent per connection event, and as a consequence, the maximum througput is very poor. Is that corrrect?. Does Cordio support the specification of min/max ce lenght?. I would really appreciate any help or any comment related to other experiments regarding this issue.
