How to Update the Modem Firmware

Regardless of the method used to update the modem firmware of your cellular-based Ewon device, the update can last between 5 to 15 minutes.

Caution

A modem firmware update is a critical process.

Make sure your Ewon device does not experience any power interruptions during the upgrade process, which can take up to 15 minutes and which includes a reboot of the Ewon device.

The modem firmware update can be performed locally or through the remote connection.

However, if possible, we recommend doing the modem firmware upgrade when you are locally connected to the Ewon

SD Card Commissioning

FTP Server

The Ewon Cosy and the Ewon Flexy can be updated using an SD card.To do so, you will need to copy the .edf file (based on your model & modem firmware target) to the SD card & insert this SD card into your Ewon device.

You can update the modem firmware of your Ewon device by following the same process as updating the OS firmware of your Ewon device:

  1. Open the modem firmware zip file.

  2. Make sure the file is named as "ewonfwr.edf". If not, rename the .edf file to "ewonfwr.edf".

  3. Copy the “ewonfwr.edf” file on the SD card. You might need to copy the .edf file first on your computer, then on the SD card.

  4. Insert the SD card into the Ewon device.

    1. The USR LED blinks quickly orange (ON/OFF each 200ms).

      This phase indicates the Ewon device is checking the validity of the SD card (e.g. proper format and valid files).

    2. The USR LED blinks slowly orange (ON/OFF each second).

      This phase indicates the Ewon device is copying the file from the SD card to its internal memory.

    3. The USR LED turns steady green.

      The Ewon device is ready to continue the procedure.

  5. Remove the SD card from the Ewon device.

  6. The USR LED switches colors every second, between red and green (this phase can last from 5 to 15 minutes).

    This phase indicates the Ewon device is processing the update file.

  7. Wait for the Ewon device to reboot.

    1. If the reboot occurs quickly after removing the SD card = it is highly probable that the update did not occur (failed or update already performed previously).

    2. If the reboot occurs a while after the SD card removal = it is highly probable that the update succeeded.

  8. Verify the new modem version at Diagnostic > Status > System Info > Info.

The Ewon device embeds an FTP server that you can use to update the modem firmware.

To do so, you need to open an FTP connection with your FTP client to your Ewon device and drop the .edf file (based on your model & modem firmware target).

  1. Open the modem firmware zip file.

  2. Make sure the file is named as "ewonfwr.edf". If not, rename the .edf file to "ewonfwr.edf".

  3. Extract the “ewonfwr.edf” file to your computer.

  4. Open your FTP client. In our case, we use the FileZIlla® software.

  5. Establish a connection to your Ewon with the “Adm” username and password. You can use:

    1. Its LAN IP address if you are connected to the same network your Ewon device is connected to.

    2. Its LAN IP or VPN address if you are connected to your Ewon device through Ecatcher.

  6. Transfer the “ewonfwr.edf” file from your computer to the Ewon device.

  7. Close the FTP connection.

  8. The USR LED switches colors every second, between red and green (this phase can last from 5 to 15 minutes).

    This phase indicates the Ewon device is processing the update file.

  9. Wait for the Ewon to reboot.

    1. If the reboot occurs quickly after closing the FTP connection = It is highly probable that the update did not occur (failed or update already performed previously).

    2. If the reboot occurs a while after closing the FTP connection = It is highly probable that the update succeeded.

  10. Verify the new modem version at Diagnostic > Status > System Info > Info.
