The BCM20732 does not support the Master/Slave scenario that you've described.
The BCM20736 will support the Master/Slave environment and is supported in the new SDK 2.0.1 available for download here: WICED Smart Docs & Downloads
I am creating a Master/Slave Blog very soon and will update you when it is posted.
Let me know if you have further questions.
Will the 20732A1 support master/slave?
