MM (MAC Mode) Command
<Networking {Addressing}> The MM command is
used to set and read the MAC Mode value. The
MM command disables/enables the use of a Max-
Stream header contained in the 802.15.4 RF
packet. By default (MM = 0), MaxStream Mode is
enabled and the module adds an extra header to
the data portion of the 802.15.4 packet. This
enables the following features:
• ND and DN command support
• Duplicate packet detection when using ACKs
The MM command allows users to turn off the use
of the extra header. Modes 1 and 2 are strict
802.15.4 modes. If the MaxStream header is dis-
abled, ND and DN parameters are also disabled.
Note: When MM > 0, application and CCA failure
retries are not supported.
MY (16-bit Source Address) Command
<Networking {Addressing}> The MY command is
used to set and read the 16-bit source address of
the RF module.
By setting MY to 0xFFFF, the reception of RF pack-
ets having a 16-bit address is disabled. The 64-bit
address is the module’s serial number and is
always enabled.
NB (Parity) Command
<Serial Interfacing> The NB command is used to
select/read the parity settings of the RF module
for UART communications.
