Connecting your Gravio Hub to the Network

The Network Setup Process

The first time you plug the Gravio Hub into a power source, it will create a wireless network. Use any device with a browser to connect to that Wifi Network:

Log in using the password graviohub

Now open your browser and enter the URL address http://192.168.100.1:8080 to access the login page:

You can log in with username gravio and password gravio to see the initial setup page:

• Set the password to something you can remember.
• Set the correct time zone. Optionally you can also set an NTP Server. Note that you will have to connect your Gravio Hub to the internet (see below) before it can connect to any NTP server.
• Set the correct Date and Time
• Set a hostname of your choice, using numbers and characters but no special characters or spaces. You will later be able to access your Gravio Hub via http://hostname.local:8080 inside your network later

You need to decide if you wish to connect to the Gravio Hub via Wifi or LAN. We recommend LAN for better reliability. If you want to shift large volumes of data, for example, to process video camera footage, LAN connectivity is a prerequisite.

WAN configuration for Gravio Hub

Gravio Hub2 also supports communication using LTE (LTE mode). You can connect directly to the Internet by inserting a nano SIM of the following carriers into the slot and enabling the WAN settings.

Japan:

Singapore:

To enable the WAN setting, ensure you have set the correct Timezone and Region, then turn on “Use WAN (LTE)” and reboot.

After rebooting, the Gravio Hub2, connects to its wireless network and connect to the IP “192.168.96.1:8080” with wifi router mode enabled to access the Update Manager.
The DHCP server will also be enabled, so the IP address assignment by DHCP will also be enabled at “192.168.96.x”.
When you connect to the “GravioHub-XXXXX” via wifi, an IP address will be assigned automatically.
If you do not use DHCP, please set a fixed IP address at “192.168.96.x/24” for the device connecting to Gravio Hub2.

Then select and set the correct APN appropriate to the SIM card you have entered and reboot again.

You will be automatically connected to the WAN after rebooting, but you can also switch manually by pressing the “Disconnect” and “Connect” buttons. Note, depending on the network quality it may take a while to connect.
When connected to the WAN, network information will be displayed on the current WAN-side IP address.

Note: If the Gravio Hub2 is assigned an IP address as a DHCP client using DHCP in a network environment connected via a wired LAN, and the LTE mode is turned on, the DHCP server on the wired LAN side may conflict with the DHCP server on the Gravio Hub2, so please do not connect to a network environment connected by a wired LAN if there is a DHCP server managing that LAN.

Connecting to Wifi

• Set the Wifi you want your Gravio Hub to connect to and set the correct password. Ensure that these settings are correct as you may lock yourself out of the Gravio Hub, in which case you will have to reset the Wifi settings by long-pressing the reset button next to the USB Type-C plug while plugged in. The Gravio logo light will turn blue to signal that Gravio Hub’s Wifi settings (and Wifi settings only) have been reset to Access Point mode and you can re-connect.

Note: The Gravio Hub is configured to only hold one Wifi settings at any one time. Therefore, if you like to add the Gravio Hub to another network, you will need to reset the Wifi settings by pressing and holding the button while plugged in until the light is lit blue. This will put the Hub back in the Access Point mode, so you can restart the configuration.

Connecting to LAN

• Enable the LAN switch and confirm with the “Apply” button. Note, that if you have both interfaces enabled, please use the LAN setting as this will take precedence.

DHCP and SSH

• Set the DHCP server or alternatively set a static IP. We recommend that you give your Gravio Hub a fixed IP within the network, either via setting a fixed IP or via DHCP tables on your DHCP server. Generally setting the fixed IP in the DHCP server is favoured, but you always have the option to set an IP in Gravio itself, too.
• Enable SSH if you like to access your Gravio Hub via SSH
  

Please note that once you connect your Gravio Hub to a new network, you will connect to the same network and access your hub via http://hostname.local:8080

Your Gravio Hub is now up and running, and you can connect to it using Gravio Studio, which you can download from the Apple, iOS or Windows App Store.

If you cannot connect to the website above, there is a chance that you have switched from Wifi to LAN but try to connect via WiFi or vice versa. Please make sure you are connecting via the right connection. If you locked yourself out of Gravio Hub, please long press the reset button while the Hub is connected to power to reset the Wifi settings to Access Point mode so you can reconnect using the password graviohub and follow the steps above (blue light).

Enabling SSH

The Gravio Hub comes with SSH support. You can enable SSH in the Update Manager under http://hostname.local:8080 in the Gravio Hub Settings tab:

The username is gravio and the password is what you have been setting.

Connecting Bluetooth Devices to your Hub

You can connect Bluetooth devices such as Bluetooth Speakers to your hub to play audio files. To do so, scroll to the Bluetooth section of the Gravio Hub Settings tab and hit the “Scan” button.

Set your device in discovery mode and it will show up on the list of available devices.

Press the “Pair” button and it will be paired:
