Firmware Update

Overview

The linux system of the miro Edge gateway and the firmware on the integrated miro EdgeCard can be updated by the user. The following sections will guide you through the updated process.

Update in the web interface

  • Download the firmware image from the downloads page.
  • In the web interface, open System->Backup / Flash Firmware and select the image under Flash new firmware image.
  • Keep Keep settings and retain the current configuration selected to keep your configuration.
  • Confirm, and wait about 3 minutes until the gateway has restarted.

Firmware 2.7

The gateway checks the Miromico signature of every image before installing it. Modified or unsigned images are refused; this check cannot be overridden. Firmware older than the installed version is refused as well; contact Miromico support if you need to return to an older version.

You can also install updates over SSH with sysupgrade or through remote management. The same checks apply.

Important

Do not disconnect power while the update is in progress.

Update from 2.6 to 2.7

A gateway with firmware 2.6 can be updated to 2.7 in the web interface as described above, with Keep settings.

Warning

The update from 2.6 to 2.7 changes the underlying operating system. It has been tested with typical configurations, but not with every possible setup. Update a single gateway first and check that it works as expected before you update further gateways. Create a configuration backup before the update, and make sure you have on-site access to the gateway in case it needs a factory reset.

When the settings are kept:

  • The network, LTE and LoRaWAN server settings, the ZeroTier configuration and the password are kept.
  • Gateways that used the LORIOT packet forwarder use the Semtech UDP packet forwarder after the update. Connect them to LORIOT with LoRa Basics™ Station instead, see configuration.
  • The antenna selection no longer exists.
  • The web interface is only available over HTTPS, see accessing the device.
  • The gateway no longer routes traffic between Ethernet and LTE.
