3. CODEGRIP link structure
CODEGRIP Suite can detect multiple CODEGRIP devices. In addition, a
single CODEGRIP device can be operated by multiple software applications.
To avoid any ambiguity, CODEGRIP utilizes the concept of links.
CODEGRIP Suite uses a link to the specific CODEGRIP device, in order to send
commands and receive responses. The link can be created, opened, and
destroyed by the user, employing some specific functions of CODEGRIP Suite.
Based on the link and its state, CODEGRIP Suite can always unambiguously
know which CODEGRIP device to use, and if the specific CODEGRIP device
is currently available. A single CODEGRIP device can have links to multiple
CODEGRIP Suite applications, while CODEGRIP Suite can have a link to only
a single CODEGRIP device at time. Still, it can easily switch the link to any
CODEGRIP device detected during the scanning process.
3.1 Link types
3.2 Link states
Depending on what type of interface is used to establish the link, there are
two types of links available: the USB link, and the WiFi link.
Each link has several different states recognized by the CODEGRIP Suite.
The link is Closed : the CODEGRIP device is not available over the
communication interface (USB or WiFi). Either it is disconnected,
nonresponsive, turned OFF, or otherwise unavailable.
The link is Available : the CODEGRIP device is available over the
communication interface (USB or WiFi). Communication packets can
reach the CODEGRIP device, and it is able to send back the response.
The link is Blocked : this state indicates that the link was blocked because
the specific CODEGRIP device is busy servicing another link.
When CODEGRIP Suite actively uses the link for issuing commands to a
linked CODEGRIP device, other applications linked to the same CODEGRIP
device will have their links in a blocked state. As soon as the task is
complete, those links will revert to the available state.
The indicator showing the current state is visible at the status bar at
the bottom of the Suite. More detailed description about the Shortcut bar
commands find in the Chapter 4.
N O T E USB link is the primary link and it has the highest priority. Some
operations, such as the firmware update, are exclusively used with
the USB link. When the USB link is active, all the WiFi links to that
specific CODEGRIP device will be forced to a closed state.
