Please take a look at this discussion: http://community.broadcom.com/message/1953#1953
"There is a patch file available on the Murata portal for the SN8200. Please register with your EVK registration code at www.murata-ws.com."
Usually module suppliers provide "platform files" these will patch into our SDK.
Perhaps you could use the rar file to update your SDK and you may find here: http://www.murata-ws.com./software/SN820x-WICED-2.4.0-patch-02.rar
Even the patch file is for version 2.4.0 but it should work for 2.4.1 as well.
Hope it helps.
