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 (for API type)
n
The AC command
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

Transmit Request frame - 0x10
Description
This frame causes the device to send payload data as an RF packet to a specific destination.
For broadcast transmissions, set the 64-bit destination address to 0x000000000000FFFF.
n
For unicast transmissions, set the 64-bit or 16-bit address field to the address of the desired
n
destination node.
If transmitting to a 64-bit destination, set the 16-bit address field to 0xFFFE, otherwise set the
n
64-bit destination address field to 0xFFFFFFFFFFFFFFFF.
Query the NP command to read the maximum number of payload bytes.
n
You can set the broadcast radius from 0 up to NH. If set to 0, the value of NH specifies the broadcast
radius (recommended). This parameter is only used for broadcast transmissions.
You can read the maximum number of payload bytes with the NP command.

Offset
Description
3
0x09
Identifies the data frame for the host to correlate with a
4
subsequent response (0x88). If set to 0, the device does
not send a response.
5-6
Command name: two ASCII characters that identify the AT
command.
7-n
If present, indicates the requested parameter value to set
the given register. If no characters are present, queries
