FTP Interface

The FTP interface can be used for:

  • Updating the Software
  • Updating the configuration *
  • Support

* NOTE: Multiples configuration's updates can be done simultaneously : (Thoses will be done in this order)
1. License update
2. Device update
3. Output update

If the license's check is KO, the product will not start.

Setup FTP client

Connect to µWiotys using a FTP client (ex:filezilla)

  • Host: $UWIOTYS_IP_ADDRESS
  • Port: 2222
  • Protocol: SFTP (SSH File Transfer Protocol)

Warning, the answer time of µWiotys' FTP can be very long, especially on fixed IP. If necessary, you should extend your FTP Client timeout to 60 seconds, see Application Example

Contact Wi6labs support team for user/password

End device configuration

LoraWan device provisioning on µWiotys can be done by FTP transfer. First, create the configuration file with proper parameters and format then connect to µWiotys with FTP and copy the configuration file into the proper directory.

Configuration file

File name

The name of the devices configuration file can be: devices_update.json or devices_update_XXXXXXXX.json

“XXXXXXXX” is the hardware serial number of the board (8 digits, upper case), it can be found on the web interface in the Overview ⇒ Information menu.

One or many devices can be add or deleted with the same update file. You can use µWiotys Online support interface to help create your update file.

Upload configuration

Upload the configuration file

Once connected to FTP server, copy the devices configuration file into the directory: /uwiotys/update_config/

You need to reboot to process the device update, you can reboot the gateway by two ways:

  • With ftp :

    • Create a file named "reboot" in directory "/update/".
    • A file XXXXXXXX_reboot_processed_yy is created once command processed.
    • Command reboot is processed if XXXXXXXX_reboot_processed_yy does not exist and each time the command file is edited.
  • With Kerlink gateway button:

    • iFemToCell: Press the reset button located on the side of the gateway.
    • iStation: Press once (and only once) the On/Off button.

Warning: an electric reboot can corrupt the update process

After a few seconds the LEDs stop blinking, wait another minute then it's possible to reconnect to the FTP. The status file will created in: /uwiotys/update_config/

  • If the update failed, you will find information into the file: devices_updates_$DATE_ERROR.log
  • If the update success, the file the devices configuration file is deleted and you will find the file: devices_updates_$DATE_SUCCESS.log

Current configuration

The devices current configuration of µWiotys is available in the directory: /uwiotys/current_config/

The file format is the same as the devices configuration file, it can be used to remove device for µWiotys config by simply changing "state" from "active" to "remove" for one or several devices and then follow the regular update procedure.

Output configuration

Configuration file

File name

The name of the output configuration file can be: output_update.json or output_update_XXXXXXXX.json

“XXXXXXXX” is the hardware serial number of the board (8 digits, upper case), it can be found on web interface in the Overview ⇒ Information menu.

Warning: an electric reboot can corrupt the update process

To test the HTTP configuration, µwiotys will send a test request with information about the Gateway (EUI, IP and MAC) and wait for a 200 OK response.

{
    "EUI": "7076FF0056050190",
    "IP": "192.168.100.143",
    "MAC": "70:76:ff:03:02:e1"
}

After a few seconds the LEDs stop blinking, wait another minute then reconnect you to the FTP. The status of the output configuration update can be found in /uwiotys/log/uwiotys_functionnal.log

Current configuration

The output current configuration of µWiotys is available in the directory: /uwiotys/current_config/

License Configuration

Configuration file

Where to get the license

See with Wi6labs if not already provided with the product.

File name

The license's file's name look like : license_XXXXXXXX.json. With "XXXXXXXX" as the hardware serial number.

Upload configuration

Upload the license

To give or update a license, the license's file has to be put in the following folder using FTP : /uwiotys/update_config/
After that step, a reboot is needed to take this license into account. You can reboot by two ways:

  • With ftp :

    • Create a file named "reboot" in directory "/update/".
    • A file XXXXXXXX_reboot_processed_yy is created once command processed.
    • Command reboot is processed if XXXXXXXX_reboot_processed_yy does not exist and each time the command file is edited.
  • With Kerlink gateway button:

    • iFemToCell: Press the reset button located on the side of the gateway.
    • iStation: Press once (and only once) the On/Off button.
