OTA Update

Updating through the application

info

In order to update your viaSens through the app, please download our free app.

Our mobile app offers a simple and intuitive way to update your viaSens to the latest firmware. The prerequisite for updating it through the application is that the device is provisioned through the application, so if you haven't provisioned your device yet, please refer to the MQTT Mode part of this documentation in order to provision it correctly.

Once we got that out of the way, we can start updating our device.

OTA updates are done on per-network basis, so first we should select the project where the network we want to update is located. Next, click on the network, and then from network settings we can select "Update nodes in this network".

tip

There are multiple hardware versions (or, as we call them, hardware indexes) of viaSens devices available, and they will grow in the future as we add new hardware features. If you have a small number of viaSens devices and you bought them at the same time, you will probably have only one hardware index.

The application will display available firmwares for hardware versions of the devices you have provisioned based on the XML file downloaded from the server. The latest firmware version available for each hardware index will automatically be selected, but if you don't want to update to the latest version, you can select other versions by clicking the "Edit" button.

warning

viaSens devices can't be downgraded through the application.

For example, if one of your devices has firmware version v1.5, and you select v1.3 in the dropdown, only devices that have firmware version older than v1.3 will get updated, and device with version v1.5 will stay at that version.

Once you've selected the appropriate version of the firmware you want to update to, we can go to the next step. Now, you should go ahead and enable hotspot on your device.

While updating the firmware your hotspot name (SSID) and password should always be sauteriot!
