WiFi Connect detects available WiFi networks and opens an access point with a captive portal. Connecting to this access point with a mobile phone or laptop allows new WiFi credentials to be configured. Connect to the opened access point on the device from your mobile phone or laptop. After connecting to the access point from a mobile phone, it will detect the captive portal and open its web page.

Opening any web page will redirect to the captive portal as well. When the network credentials have been entered, WiFi Connect will disable the access point and try to connect to the network. If the connection fails, it will enable the access point for another attempt. If it succeeds, the configuration will be saved by NetworkManager. For a complete list of command line arguments and environment variables check out our command line arguments guide.

This integration is accomplished through the use of two shared files:. Given these results, it is probable that most dongles with Atheros or Ralink chipsets will work. The following dongles are known not to work as the driver is not friendly with access point mode or NetworkManager :.

WiFi Connect is expected to work with all balena. If you're having any problem, please raise an issue on GitHub or contact usand the balena. WiFi Connect is free software, and may be redistributed under the terms specified in the license.With balenaOS 2. All of the network configuration for balenaOS can be done though files in the boot partition of your device.

If you have a freshly downloaded balenaOS. In the boot partition you will find a directory called system-connections. The system-connections directory consists of a set of connection files—one file per connection. The file resin-sample. If you added a WiFi connection from the dashboard when you downloaded your image, you should see its configuration file already created for you under the name resin-wifi. You will notice that there is no file for ethernet, this is because NetworkManager will always set up a default ethernet connection.

If you want a specific configuration for the ethernet connection you will need to create a new connection file for it. Most of the allowed options for these connection files can be found in the NetworkManager settings reference. If you want to add multiple different WiFi credentials, then simply make a copy of resin-wifi or resin-sample. You can also add the autoconnect-priority integer values in each file to define the priority of each connection when the device has multiple WiFi connections it can connect to.

To set WiFi as the default route to the internet, you need to force eth0 to have a low route metric and set the never-default option. Note: Depending on the device, the interface name may not be eth0. To check the correct name, you can run ifconfig from the web terminal found on the device dashboard. The connection file also defines what kind of security the network expects.

If you want to set up a network with more elaborate security requirements, checkout the NetworkManager settings reference page. If you want to connect to an unsecured WiFi network, simply remove the [wifi-security] section. An example for Eduroam network for students and universities is shown in the config below. You'll need to change the listed fields for your educational institution.

Contact your educational institution's IT department for the connection specifics. By default, the WiFi regulatory domain for your device is not set until it is connected to a network. If you need your device to connect at first boot to channels that may be restricted in some countries, you can specify the regulatory domain in the config.

Regulatory domain is set using the country field. As an example, if you are deploying your device in Great Britain and need it to connect to channel 12 or 13, you would set "country":"GB". Setting a static IP is possible by adding a few fields to the [ipv4] section of your connection file.

The Balena HPC cluster can only be accessed from within the campus network, it is not available from external connections. User should start the Xming service on the Windows system before opening a session to view graphical output.

The Balena cluster is a shared research resource available to all researchers in the University. There may be many users logged on at the sametime accessing the filesystem, hundred of jobs my be running on the compute nodes, with a hundred jobs queued up waiting for resources.

The two login nodes are shared among all users of the service. A single user running computational workloads will negatively impact performance and responsiveness for other users.

Instead, submit batch jobs or request interactive sessions on the compute nodes as detailed below. Kinldy refrain from running production workloads on the ITD nodes. This will impact other users having a fair access to the limited resources available on the ITD nodes.

This however does not include a sensor for gas content and so if you use this the air quality readout is derived from humidity and temperature target values. Air quality metrics are not available with these sensors. The sensor provides a reading for Indoor Air Quality IAQ which is a range from 0 to where lower is better, and displays it with a web interface provided by Grafana.

You can get hold of the Bosch BME sensor on a breakout board from a variety of vendors too, all at varying costs.

If you don't want to do any soldering and are happy to sacrifice the air quality reading, you can also use the Sense HATwith the added bonus that you'll get a smiley face showing on the LED matrix! However, if you're buying hardware specifically for this project, get one of the BME options below, don't buy a Sense-HAT just for this! If required, this project supports offsetting of the measured values before they are recorded in the database.

Information on the 1-wire interface is available at pinout. More information about device tree overlays and other advanced boot settings for the Raspberry Pi is available in the BalenaOS docs and BalenaCloud management reference section. Don't forget you'll need a pullup resistor between the Vin and data lines. If no ID is given, the first sensor found will be used. For more information about how to find the ID for 1-wire devices, the Pi Hut guide referenced above, or this Raspberry Pi tutorial are useful.

Versions of balenaSense after v1. Configure the following environment variables within the balenaCloud dashboard to enable the feed to the InfluxDB Cloud 2. Configure the following environment variables within the balenaCloud dashboard to enable a feed to an external InfluxDB instance:.

The default hostname is the first seven characters of the unique device UUID, available on the dashboard. Note that if you change the hostname, the topic will still use the first seven characters of the device UUID. This will then be passed to the output database along with the measurements, allowing you to filter and plot metrics from each device individually. A full guide covering the initial setup of this project is available on our blog. We published an additional blog covering the setup of a fleet of balenaSense devices to feed to a central database on our blog here.

Python Shell.Multiple container applications are supported, beginning with balenaOS v2. To run multiple containers, you will need to create or upgrade to a starter or microservices type application and include a docker-compose.

You can reference the multicontainer documentation for more details on the supported configurations. Note: If you do not see an option to choose a starter or microservices application type, a multicontainer compatible OS version has not yet been released for the selected device type. If you are running a Docker-in-Docker setup, which builds a single application container on the balena servers but has a docker-compose. Then when you run Docker Compose in your container, you can use the -f flag with the new file name: docker-compose -f dind-compose.

It is possible to have devices of different types in the same application, as long as the devices share the same architecture. However, you could not have any Intel NUC devices as part of the same application, as those devices have x processors. Regardless of type, all devices in your application will get the same container images.

This means that if you have mixed device types you'll need to use an architecture-specific base image in your Dockerfilerather than one based on device type. You can then easily push project-B to your application by just doing git push balena master -f.

The extra -f on the command forces the push and resets the git history on the git remote on balena's backend. You should now have project-B running on all the devices in the application fleet.

Note that once you have successfully switched to project-B you no longer need to add the -f on every push, for more info check out the docs on forced git pushes. On the device we have a writable data partition that uses all the free space remaining after reserving the required amount for the host os. In order for a balena device to get outside of the local network and connect to the balena API, there are a few core network requirements.

Each of these should work with outward only and inward once outward connection established firewall settings. If your application uses a single container, it will be run in privileged mode by default and will have access to hardware in the same way as a vanilla Linux system.

It's actually pretty easy. Have a look at the network setup section of our documentation. In general, most network configurations can be achieved by changing the NetworkManager configuration file.When you push updates, the terminal session is automatically closed.

To restart the terminal session, simply close the terminal session and restart it once the update is complete. In some cases social logins can be disrupted or completely borked by Adblocker or browser extensions such as BrowserShark.

Line endings differ between windows and the unix-y world they used to be different again for mac but not for many yearswhich can result in issues.

To resolve this, you will need to configure git to auto convert line endings. If your device keeps dropping offline, it may be worth switching to 5GHz band wifi dongle, as we have seen cases where 2. The qemu: Unsupported syscall: is a warning that the getrandom 2 system call is not implemented by our emulation layer, qemu. It can be safely ignored.

The Raspberry Pi 2 requires an OS download specific to its architecture. If a Balena ASCII logo appears with a prompt to check your dashboard, then you are likely experiencing connectivity issues. Check ethernet cables are connected properly and that provided WiFi credentials are correct and try again, also let us known that the LED notification didn't show for you.

If you are presented with a 'recovery login' prompt this usually indicates an issue with the SD card itself or corruption of data on the SD card, and is likely caused by one of the following If you are having issues with your RPI3 connecting to your wifi, make sure to check that the 2. This is either because it is not connected to the network or because the network ports which balena relies on are blocked in some way.

If you have a screen attached to your Raspberry Pi and notice that there is a small flashing colorful square in the top right of the screen, it could be the case that your power supply or USB cable is not suitable. Additionally, if the onboard PWR LED is flashing intermittently, this too could indicate issues with the power supply.

Connectivity If a Balena ASCII logo appears with a prompt to check your dashboard, then you are likely experiencing connectivity issues. SD Card Corruption If you are presented with a 'recovery login' prompt this usually indicates an issue with the SD card itself or corruption of data on the SD card, and is likely caused by one of the following:- You've copied data onto the card but disconnected it from your computer without properly ejecting it - some data may have not finished being copied yet and thus the card is corrupted - reformat your SD card and copy files over to it and try again.

The SD card itself is faulty - older SD cards, especially ones which have been used a lot and thus may also be physically worn at the pins can be unreliable, resulting in data corruption.
