Additional Tips
The Polycom HDX system does not provide flow control. If the connection
is lost through restarting the system or other means, you must re-establish
the connection.
The API processes one command at a time.
Polycom does not recommend sending multiple commands
simultaneously without a pause or delay between them.
For commands with a single action and a single response: A delay of
200 milliseconds between commands is usually sufficient. Examples of
these commands include the commands for switching cameras (camera
near 1), sending content (vcbutton play), and checking the status of the
audio mute (mute near get).
For commands with a single action and a more extensive response: The
time required to receive the response, and thus the time between
commands, may be longer than 200 milliseconds. The response length,
which can vary in size, determines the time required to receive the
response. Examples of these commands include the commands for
retrieving the local address book (addrbook all), the global address book
(gaddrbook all), the list of system settings (displayparams), and system
session information (whoami).
When developing your program, always allow enough time for the
response to the requested command to complete before sending another
command.
Do not send any commands while an incoming or outgoing call is being
established.
The API provides feedback status in two ways: registrations or polling.
It is only required that you send registration and notification API
commands once, because the registrations become written into Flash
memory and are retained even upon restarting the system.
