AT Command Frame - 0x08
Description
Use this frame to query or set command parameters on the local device. This API command applies
changes after running the command. You can query parameter values by sending the AT Command
Frame - 0x08 with no parameter value field (the two-byte AT command is immediately followed by the
frame checksum). 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 AT Command - Queue
Parameter Value frame - 0x09 instead.
When an AT command is queried, a AT Command Response frame - 0x88 response 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 frame.
Format
The following table provides the contents of the frame. For details on frame structure, see API frame
format.
