Environment Variables Reference

The following environment variables can be overridden by developers. The procedure is described in the section on modifying AuterionOS.

Network Configuration

Skynode

Variable	Value	Description
AOS_ZEROTIER_ID	String	ID of your Zerotier network
AP_CONFIGURE_ETHERNET_IP	IP address in the format "10.41.1.1" or "dhcp"	IPv4 address that will be assigned to the Ethernet interface. Can also be set to "dhcp"
AP_CONFIGURE_ETHERNET_IP_PREFIX	Integer between 0 and 32	Amount of prefix bits. For example "=24" would create the subnet 255.255.255.0
RESINCONF_LINK_GCS	String with IPv4 address and port. For example "192.168.144.11:14550"	Forwards all MAVLink telemetry to a specific IPv4 address and UDP port. Useful for when the exact IPv4 address of the ground station is known and pairing cannot be used.
AP_CONFIGURE_ETHERNET_ROUTING	0 or 1	enable routing over ethernet (0=disabled, 1=enabled)
WIFI_DISABLED	0 or 1	If set, the wifi interface will be disabled
LTE_DISABLED	0 or 1	If set, the modem interface will be disabled
NVIDIA_ETH_IP	IP address in the format "172.20.50.50" or not set	Specify IPv4 address of AI Node if connected to Skynode. Required for forwarding AuterionOS updates to AI Node.

AI Node

Variable	Value	Description
AOS_ZEROTIER_ID	String	ID of your Zerotier network
AINODE_ETHERNET_BRIDGE_ENABLE	"1" for enabled	When enabled, the AI node will bridge its two Ethernet interfaces
AINODE_CONFIGURE_ETHERNET_BRIDGE_IP	IP address in the format "172.20.50.50" or not set	Specify IPv4 address for Ethernet bridge. Requires Ethernet bridge to be enabled. If variable is not set it will default to 172.20.50.50
AINODE_CONFIGURE_ETHERNET_BRIDGE_MASK	Integer between 0 and 32 or not set	Amount of prefix bits for bridge network. Requires Ethernet bridge to be enabled. For example "=24" would create the subnet 255.255.255.0. Defaults to "16" when not set.
AINODE_CONFIGURE_ETHERNET0_IP	IP address in the format "172.20.50.50" or not set
AINODE_CONFIGURE_ETHERNET0_IP_PREFIX	Integer between 0 and 32 or not set

Pairing Settings

Variable	Value	Description
PAIRING_MNG_TYPE	"MH", "SILVUS", "ZT" or "DISABLE"	Configure Vehicle Pairing for various types of radios. Disable when using custom data links.

Payload Settings

Variable	Value	Description
PAYLOAD_MANAGER_GCS_LINK_IP	IPv4 address, or first three blocks thereof	IPv4 address of the interface that the GCS will be instructed to use to download camera definition files. Configured automatically when Pairing is used. Default on Skynode is 10.41.1
PAYLOAD_MANAGER_USB_ONLY	1	If set, the payload manager won't save pictures if no USB stick is plugged
PAYLOAD_MANAGER_VIDEO_BITRATE	Integer	Video encoding bitrate in kbps (default 2000)
PAYLOAD_MANAGER_VIDEO_MTU	68-1500	Video MTU size (default 1400)
