Hi,

Connection Parameter Request (on the link layer) as a peripheral is not supported by the SoftDevice controller. This is an old feature from Bluetooth 4.1 but there has not been much interest for it. A peripheral can still do connection parameter update requests on the GAP layer, which is how connection parameter updates are normally initiated from the peripheral side.

Thanks. Do you know how to enable these features of SoftDevice controller?

Hi,

This will not work. This list of Kconfigs is not indended to be user configurable, and in any case, only specifies what the SoftDevice controller supports. Adding the BT_CTLR_CONN_PARAM_REQ_SUPPORT config here will not make it support the specific feature, but it will make it look like it supports it. (Also, where you should normally add other configurations, is in project specific configurations, and not in the Kconfig files themselves).
