3. Advanced Programming
Programming the Module
AT Command Example
Horner provides RADIOSET
Software for programming
the module using AT
Commands.
To install, double‐click the
"RADIOSET.exe" file, then
follow the prompts of the
installation screens.
Binary Command Example
For information about entering and exiting AT and Binary Command Modes, refer to the
Command Mode section [p14].
To Send AT Commands (Using the Terminal tab of the RadioSet Software)
Example: Both of the following examples change the module's destination address to 0x1A0D and
save the new address to non-volatile memory. <CR> stands for "Carriage Return".
Method 1 (One line per command)
Send AT Command
+++
ATDT <Enter>
ATDT1A0D <Enter>
ATWR <Enter>
ATCN <Enter>
Method 2 (Multiple commands on one line)
Send AT Command
+++
ATDT <Enter>
ATDT1A0D,WR,CN <Enter>
Note: In order to use a host PC and the RADIOSET Software Terminal tab to send data to the module,
the PC com port settings must match the following module parameter values: baud, parity & stop
bits.
Use the "PC Settings" tab to configure PC com port settings to match module parameter values.
[Refer to BD (Baud Rate) and NB (Parity) Commands for module parameter values.]
To Send Binary Commands:
Example: Use binary commands to change the WCM802 / WCM900 Module's destination address
to 0x1A0D and save the new address to non-volatile memory.
1.
RT Command must be set to "1" in AT Command Mode to enable binary programming.
2.
Assert CMD (Pin 5 is driven high).
3.
Send Bytes: 00
0D
1A
08
4.
De-assert CMD (Pin 5 is driven low)
Note:
(pin 1) is de-asserted high when commands are being executed. Hardware flow control
must be disabled as
will hold off parameter bytes.
20 JUN 2005
(Enter Binary Command Mode)
(Send DT (Destination Address) Command)
(Least significant byte of parameter bytes)
(Most significant byte of parameter bytes)
(Send WR (Write) Command)
(Exit Binary Command Mode)
System Response
OK <CR> (Enter into Command Mode)
0 <CR> (Read current destination address)
OK <CR> (Change destination address)
OK <CR> (Write to non-volatile memory)
OK <CR> (Exit Command Mode)
System Response
OK <CR> (Enter into Command Mode)
0 <CR> (Read current destination address)
OK <CR> (Execute commands)
