  • device identifier (DEVID);
  • parent piconet controller (PNC) ceasing operations;
  • PNC responsibilities


There are two types of dependent piconets defined in the standard: child and neighbor. The most obvious difference between a child and a neighbor piconet is the device identifier (DEVID) that is used in the parent piconet. The first task in starting a dependent piconet is to associate with the piconet controller (PNC) of the parent piconet. The device (DEV) joins the piconet using the Association Request command and follows the normal association process. The parent and neighbor PNCs can carry on limited communications during the time periods marked “N-P,” although this communication is restricted to the commands necessary to maintain the neighbor piconet. When the parent PNC stops the parent piconet using the shut down procedure, the dependent piconets will need to adjust for the loss of their synchronization. The parent PNC is allowed to force a dependent piconet to cease operations.
