AT Command Response frame - 0x88
Description
A device sends this frame in response to an AT Command (0x08) frame and a queued AT command
0x09. Some commands send back multiple frames; for example, the ND command. This command
ends by sending a frame with a status of 0 (OK) and no value. In the particular case of ND, a frame is
received via a remote node in the network and when the process is finished, the AT command
response is received. For details on the behavior of ND, see ND (Network Discovery).
Format
The following table provides the contents of the frame. For details on frame structure, see API frame
specifications.
Framedata
fields Offset Description
Frame type 3 0x88
Frame ID 4
Identifies the data frame for the host to correlate with a subsequent ACK
(0x08 or 0x09). If set to 0, the device does not send a response.
AT
command
5-6 Command name: two ASCIIcharacters that identify the command.
Command
status
7
0 = OK
1 = ERROR
2 = Invalid command
3 = Invalid parameter
Command
data
8-n The register data in hexadecimal format. If the host sets the register, the
device does not return this field.
Example
If you change the BD parameter on a local device with a frame ID of 0x01, and the parameter is valid,
the user receives the following response.
