Local AT Command Request - 0x08
Response
frame: Description
Description
This frame type is used to query or set command parameters on the local device. Any parameter that
is set with this frame type will apply the change immediately. If you wish to queue multiple parameter
changes and apply them later, use the
When querying parameter values, this frame behaves identically to
-
0x09: You can query parameter values by sending this frame with a command but no parameter
value field—the two-byte AT command is immediately followed by the frame checksum. When an AT
command is queried, a Description frame is populated with the parameter value that is currently set
on the device. The Frame ID of the 0x88 response is the same one set by the command in the 0x08
request frame.

value and returns the result in the response.
