At Command - Queue Parameter Value Frame - 0X09 - Digi XBee 3 ZigBee User Manual

Frame descriptions

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:
The AT Command (0x08) frame
n
The AC command (as either a 0x08 or 0x09 frame in API mode)
n
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
format.

Parameter value
(BD7 = 115200 baud)
(optional)
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.
