Hi Harrison ,
Thanks for your previous reply.
But when new device come ,first it should be paired ,as it does not know the Channel id of the Master .so for aquiring Channel id ,slave will set it channel id parameters as WIld Card (Assuming the channel id of the master is not known to the slave). For this it will go in the pairing mode and we know for pairing the pairing bit on both the master and slave should be the same.
If the pairing bit of Master and slave do not match then, how the master and slave will be paired/communicate?
