ESC Connections

AQ ECU allows connecting to one or more ESCs at the same time.  The number connected ESCs is limited only by how many USB ports (and serial adapters for ESC32 v2) are available.  This is especially convenient with the ESC32 v3 on-board USB interface.  For example one could connect to all ESCs on a quad at the same time to quickly upload or compare settings, update firmware, etc.

Note for ESC32 v3 USB connections: The “STM virtual” serial (COM) port will not show up in the list of available ports until the ESC is physically plugged in and the USB driver is loaded (usually signaled by the operating system with an audio and/or visual indicator).  Wait for the driver to load before selecting the port or trying to connect.  If the USB link is later removed, the port will become marked as “INVALID” in the ports selector list (but will not disappear).  Always try to disconnect the link manually (using the Disconnect button) before removing the USB cable, otherwise you may experience errors.

ecu_conn_list_exp Each ESC on a unique port is listed in the ESC Connections window.  Selecting an ESC in the list will load the current connection properties (port, speed, and link status), and make it the active ESC for all ECU functions (configuration, calibration, telemetry, etc).  The [C] or [D] next to each ESC name indicate if the link is currently connected or disconnected.
ecu_conn_active_title Information about the currently active ESC is always shown in the window title underneath the Connection Properties window. In this example image the active ESC is an ESC32 v3 with firmware version 3.2.7.  The link status is shown on the right side as [CONN] or [DISC] for connected and disconnected, respectively.
ecu_conn_btn_connect ecu_conn_btn_disconnect The Connect and Disconnect buttons also serve as visual indicators of the current connection (link) status.
Keyboard shortcut is: CTRL-SHIFT-C (CMD-SHIFT-C on Mac).
ecu_conn_btn_delete This button will remove an ESC connection from the list entirely and make the port available for a new connection.  This is the recommended way to disconnect from an ESC when swapping between different ESCs on the same serial adapter (COM port).
Keyboard shortcut is: CTRL-SHIFT-R (CMD-SHIFT-R on Mac).
ecu_conn_btn_new Add a new ESC connection.  This will deselect any active ESC and allow for a new one to be added.  An unused Port must be available to create a new connection.
Keyboard shortcut is: CTRL-N (CMD-N on Mac).
ecu_conn_btn_rename Rename an ESC.  This button is only available when connected to an ESC32 v3.  A descriptive name may be assigned to each individual ESC to help identify individual units at a glance.  For example they could be named by their position on a MR setup (front left, front right, etc), and/or with their CAN ID.  The assigned name is saved on the local computer only.
Keyboard shortcut is: CTRL-R (CMD-R on Mac).
ecu_conn_btn_collapse This button will collapse or expand the list of connected ESCs.  The collapsed view offers a slightly more compact interface.
Keyboard shortcut is: CTRL-E (CMD-E on Mac).
ecu_conn_status_window This windows shows status messages about the progress and results of various requested ESC operations, such as connection or disconnection, parameter loading or saving, program or ESC errors, and so on. Messages in black are only informational, green indicates success of an operation, orange indicates a warning, and red means some error has occurred.
