Ewon Cosy WIFI
Ewon Flexy with WIFI extension card
ISSUE / QUESTION / SYMPTOM
An Ewon is being shipped to site and needs the WIFI SSID and Password configured before shipping.
POSSIBLE CAUSES / ANSWER
There are two options to resolve this issue.
Use the Talk2m wizard in eCatcher to configure the device. This will generate a configuration file with all the settings needed to configure the Ewon. The file can be placed on an SD card or USB drive and inserted into the Flexy or FTP'd into the root director.
The wizard can be found in eCatcher under the Talk2m connectivity in the Ewon properties.
If the Ewon is already configured WIFI and talk2m you can update the SSID and password from the comcfg. After logging into the Ewon navigate to Setup > System > Storage > Edit COM cfg .
Update the WifiSSID parameter with the new SSID and WifiPSK parameter with the new password. After updating the parameters make sure to save the settings at the top. A Reboot is required for the changes to take effect. The password will be stored encrypted after the reboot.
