AT Command - Queue Parameter Value frame - 0x09
Description
This frame allows you to query or set device parameters. In contrast to the AT Command (0x08)
frame, this frame sets new parameter values and does not apply them until you issue either:
n The AT Command (0x08) frame
n The AC command (as either a 0x08 or 0x09 frame in API mode)
When querying parameter values, the 0x09 frame behaves identically to the 0x08 frame; the response
for this command is also an AT Command Response frame (0x88).
Format
The following table provides the contents of the frame. For details on frame structure, see API frame
format.
Frame data fields Offset Description
Frame type 3 0x09
Frame ID 4
Identifies the data frame for the host to correlate with a
subsequent response. If set to 0, the device does not send
a response.
AT command
5-6 Command name: two ASCII characters that identify the AT
command.
Parametervalue
(BD7 = 115200 baud)
(optional)
7-n If present, indicates the requested parameter value to set
the given register. If no characters are present, queries
the register.
Example
The following example sends a command to change the baud rate (BD) to 115200 baud, but does not
apply the changes immediately. The device continues to operate at the previous baud rate until you
apply the changes.
Note In this example, you could send the parameter as a zero-padded 2-byte or 4-byte value.
