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

Description
Start Delimiter
Indicates the start of an API frame.
Length
Number of bytes between the length and checksum.
Frame type
Queue Local AT Command Request - 0x09
Frame ID
Identifies the data frame for the host to correlate with a
subsequent response.
If set to0, the device will not emit a response frame.
AT command
The two ASCII characters that identify the AT Command.
If present, indicates the requested parameter value to set the
value
given register at a later time.
(optional)
If no characters are present, it queries the current parameter
value and returns the result in the response.
Checksum
0xFF minus the 8-bit sum of bytes from offset 3 to this byte
(between length and checksum).
