IEEE 802.15.4-2003 frames
b01: Acknowledges only frames with
version number 0 or 1, i.e. frames
according to IEEE 802.15.4-2003/2006
b10: Acknowledges only frames with
version number 0 or 1 or 2

independent of the FCF frame version
number
Promiscuous Mode or Sniffer
The promiscuous mode is described in IEEE 802.15.4-2006, section 7.5.6.5. This mode
is further illustrated in Figure 5-9. According to IEEE 802.15.4-2006, in promiscuous
mode the MAC sub layer shall pass received frames with correct FCS to the next higher
layer without further processing. This implies that received frames should never be
automatically acknowledged.
In order to support sniffer application and promiscuous mode, only second level filter
rules as defined by IEEE 802.15.4-2006, section 7.5.6.2, are applied to the received
frame.
Table 5-11 shows the RX_AACK configuration registers required to setup a typical
IEEE 802.15.4 compliant device which operates in promiscuous mode.
