Using a single AM_ADDR to Communicate to Multiple Slaves?
Original Post: groups (eGroups Msg. ) Date: 2000-09-21
One question occasionally asked is whether it is
possible to assign one AM_ADDR to a couple of (group) of slaves and thus
send one message (i. e. a command) to these devices simultaneously
It is not possible to assign a multiple slave
specific AM_ADDR , the baseband can only assign one AM_ADDR per
slave (otherwise we could have more than seven active slaves per
master).Instead there is a group abstraction in the L2CAP layer which
resolves to a group of CIDs (local Channel identifiers), which in turn
represent a number of BD_ADDRs.
