MY (Source Address) Command
AT Command: ATMY
Binary Command: 0x2A (42 decimal)
Parameter Range: 0 – 0xFFFF
Default Parameter Value: 0xFFFF (Disabled,
DT (Destination Address) parameter serves as
both source and destination address.)
Number of bytes returned: 2
Related Commands: DT (Destination
Address), HP (Hopping Channel), ID (Modem
VID), MK (Address Mask)
<Networking & Security> Set/Read the source
address of the modem.
NB (Parity) Command
AT Command: ATNB
Binary Command: 0x23 (35 decimal)
Parameter Range: 0 – 4
Parameter
Value
Configuration
0
8-bit (no parity or
7-bit (any parity)
1 8-bit even
2 8-bit odd
3 8-bit mark
4 8-bit space
Default Parameter Value: 0
Number of bytes returned: 1
<Serial Interfacing> Select/Read parity settings
for UART communications.
PK (Maximum RF Packet Size) Command
AT Command: ATPK
Binary Command: 0x29 (41 decimal)
Parameter Range: 0 – 0x800 [Bytes]
Default Parameter Value: 0x800*
(2048 decimal)
Number of bytes returned: 2
Related Commands: BR (RF Data Rate) RB
(Packetization Threshold), RO (Packetization
Timeout), WN (Warning Data)
<RF Interfacing> PK Command is used to
set/read the maximum size of RF packets. The
maximum packet size can be used along with
RB/RO to implicitly set the channel dwell time.
If PK is set above 256 and BR is subsequently
changed to 0, then PK will automatically be
lowered to 256 and a warning will be raised (see
BR (RF Data Rate) and WN (Warning Data)
Commands for details).
Changes to this parameter may have a secondary effect on the RB (Packet Control Characters)
Parameter. RB must always be less than or equal to PK. If PK is changed to a value less than the
current value of RB, RB is automatically lowered to be equal to PK.
