Connecting
KH Control connects to a MAVLink source over a network link. The connection is shared across all actions and can be configured the Connection tab of any action.
Connection settings
Four connection types are supported. Once the settings are entered, press Connect or Disconnect to open or close a connection. If the connection fails to open double check the settings have been entered correctly and the remote side is active.
| Type | Description |
|---|---|
| WebSocket | Connects to a WebSocket server. |
| TCP | Connects to a TCP server. |
| UDP | Listens for incoming UDP packets on a given port. |
| UDP Client | Sends UDP packets to a address and port. |
Address
The IP address or hostname of the MAVLink source. Not required for UDP, which listens for incoming connections.
Port
The port number of the connection.
Signing key
If your MAVLink setup uses packet signing, enter the signing key here. Leave blank to disable signing. More information on signing can be found in the MAVLink Guide.
Connection action
The Connection action provides dedicated connect and disconnect buttons on the Stream Deck. This is useful for quickly switching connections, without having to open the action settings. The action will feedback if its connection is active.
Connect: global settings
Connects using the settings configured in the Connection tab. Use this for a simple connect button.
| State | Display | Description |
|---|---|---|
| Not connected |  | KH Control is not connected. |
| Connected |  | KH Control is connected using the global settings. |
Connect: custom settings
Connects using connection details configured on the action itself. This allows different buttons to connect to different MAVLink sources. The Display text field labels the button so it is easy to identify on the Stream Deck. The settings are the same as the those for the global connection. Custom text can be added to give a more memorable name to the connection.
| State | Display | Description |
|---|---|---|
| Not connected |  | KH Control is not connected. |
| Connected |  | KH Control is connected to the custom connection. |
TIP
Use multiple Connection actions with custom settings to switch quickly between vehicles or ground station configurations.
