BoltGATE 20-31

The BoltGATE 20-31 is a modular edge gateway that can be extended in physical capabilities by plugging add-on devices like the Eurotech BoltAIR.
The plugging of additional components can require few changes to the ESF component configuration that will be described in the following paragraphs.

GPS Configuration

For the BTGATE-20-31-21, the GPS device USB address is 1-7. When a BTAIR-20-31-11 is plugged to the main board, the reference for the ESF Position Service needs to be updated to /dev/ttyACM1 to let ESF read the position values.

🚧

The internal and BTAIR-20-31-11 modem provide additional GPS devices. In standard gateway SKUs the antenna for these GPS devices are not connected, even if ESF can manage them. So, they must not be enabled using the ESF UI to avoid undesired behaviors.

Ethernet Configuration

The default configuration of the Ethernet interfaces for a BTGATE-20-31-21 is the following:

Interface Name

Gateway Label

Status

eno1

ETH2

Enabled for LAN - Static address 172.16.0.1 with DHCP server

enp2s0

ETH1

Enabled for WAN - DHCP Client

enp5s0

ETH0

Enabled for LAN - DHCP Client

When a BTAIR-20-31-11 is plugged to the BoltGATE, the ethernet setup is as follows:

Interface Name

Gateway Label

Status

eno1

ETH2

Enabled for LAN - Static address 172.16.0.1 with DHCP server

enp2s0

ETH1

Enabled for WAN - DHCP Client

enp13s0

ETH0

Disabled

Wireless Configuration

For the BTGATE-20-31-21 and BTGATE-20-31-31 the integrated wireless interface is named wlp1s0
By default, the interface is disabled.

When a BTAIR-20-31-11 is plugged to a BoltGATE 20-31, a new interface named wlp6s0 will be available. It is disabled by default in ESF.

Modem Support

ESF completely supports both the BoltGATE 20-31 internal modem and the BTAIR-20-31-11 modem.

Journald persistence

EL 20.1.0 uses in RAM journal
EL 30.0.0 uses persisted journal

Clock Service

Chrony-advanced option in the clock service configuration can be selected and used only in EL 30.0.0 images.
