S02
– Preferred PAN ID
Description
The 802.15.4 PAN ID.
Operations
R/W LOCAL
R/W REMOTE
Becomes effective
When Joining or establishing a PAN
Notes
Two networks operating on the same
channel with the same PAN ID, but a
different EPID are detected to be in conflict
with each other. PAN ID conflicts are
detected by the stack and resolved by one of
the networks dynamically changing its PAN
ID.
The preferred PID does not affect the
AT+JPAN command
Storage
Non-Volatile
Parameters
<PID>
Where <PID> represents a 16-bit hexadecimal
number
Range
0000
– FFFF
When establishing a PAN the coordinator will pick
a random PAN ID if S02 is set to 0000. If set to
any value between 0001 and FFFF this number will
be used as PAN ID instead, unless trying to use a
PAN ID which already exists on the same channel.
In this case a random PAN ID will be used instead.
When joining only a PAN with the ID stored in S02
will be joined unless S02 is set to 0000. In this
case the next best PAN which allows joining is
joined.
Factory Default
0000
SW release
R300
S03
– Preferred Extended PAN ID
Description
The extended PAN ID.
Operations
R/W LOCAL
R/W REMOTE
Becomes effective
When Joining or establishing a PAN
Note
The EPID is used for PAN ID conflict
detection. It is therefore recommended to
use a random EPID at all times.
The preferred EPID does not affect the
AT+JPAN command
Storage
Non-Volatile
Parameters
<EPID>
Where <EPID> represents a 64-bit hexadecimal
number
Range
0000000000000000
– FFFFFFFFFFFFFFFF
When establishing a PAN the coordinator will pick
a random EPID if S03 is set to all 0‟s. If set to any
other value this number will be used as EPID
instead.
When joining only a PAN with the EPID stored in
S03 will
be joined unless S03 is set to all 0‟s. In
this case the next best PAN which allows joining is
joined.
Factory Default
