ATTRIBUTE_GETALL
The ATTRIBUTE_GETALL command provides the ability to read out the supported attributes of the device
being queried. The command itself does not report the values of the attributes but rather, the attribute numbers
supported by the device itself. This command was added as an optimization for the host to report the
"discoverable" device attributes.
NOTE The maximum command/response frame is limited to 240 bytes due to the memory constraints of the
devices queried. If the response does not fit in the 240-byte response frame, then it is up to the application
to parse the response and determine where the command should pick up. The command set has
provisions that support this feature.
