3G Modem Firmware Updated

A firmware is a software that is embedded into a hardware device.

This firmware controls how your device behaves. You might already be familiar with this type of file as they are needed to update your Ewon devices.

As a complex component, the modem can also need this kind of operation: a modem firmware update.

Why update?

This new modem firmware provides bugs fixing implying instability due to mobile ISP modification of their cellular networks.

If you - or your client(s) - encountered recently 3G stability issues on an Ewon or Ewon PPP Watchdog, then we suggest the upgrade of the modem firmware to this new version.

Compatibles devices

The compatible devices are the following ones:

  • Ewon Flexy embedding a 3G cellular (FLB3202_01) extension card;
  • Ewon Cosy 131 3G model (EC6133D_01).

How to?

To update the modem firmware, 2 different methods exist:

  • Use the SD card commissioning.
  • Use the FTP server of the Ewon.

Regardless of the method used to update the modem firmware of your 3G-based Ewon, the update can last between 5 to 15 minutes.

You must update the modem firmware while the Ewon is already powered on.

SD Card Commissioning

The Ewon Cosy 131 and Ewon Flexy can be updated using an SD card.

To do so, you will need to copy the below .edf file on the SD card and insert this SD card into your Ewon.

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