In Field Commissioning

In Field Commissioning#

It may sometimes be desirable to update a charger’s provisioned settings. The various supported commissioning methods are explained below.

Switch from LTE or Ethernet to Wi-Fi TLS#

Ethernet only applies for amina M

It is possible to switch the charger’s network interface from LTE or Ethernet to Wi-Fi TLS.

Notes:

  • This method can only be used if the charger is provisioned to use LTE or Ethernet

  • A Wi-Fi AP must be reachable from the charger’s location

  • The change is only persisted if the charger is able to establish a connection to the CSMS endpoint using Wi-Fi TLS. If no connection was made and the charger reboots it will revert back to using LTE/Ethernet

  • If persisted it is not possible to switch back to LTE

Instructions#

Switch from LTE or Ethernet to Wi-Fi TLS#

  • Ensure the charger is disconnected from power

  • Take note of the charger’s current rotary switch position (e.g. take a photo)

  • Set the charger’s current rotary switch to position 0

  • Connect the charger to power (you will see LED rapidly blinking white)

  • Wait for 30 seconds to allow the charger finish initializing itself

  • Hold any NFC card against the charger for at least 5 seconds

  • Ensure the charger has switched to using Wi-Fi (the LED should be rapidly be blinking purple)

  • Scan for Wi-Fi APs on your phone/computer until a Wi-Fi AP with SSID equal to the charger’s serial number appears

Access the Wi-Fi Module’s Captive Portal#

  • Connect your phone/computer to the Wi-Fi AP hosted by the charger

  • Open a web browser and go to: 192.168.88.1/connect

  • Enter the new SSID & password for your AP

  • Click the Submit button

  • Wait for 30 seconds to allow the charger to reconfigure itself and connect to the new Wi-Fi AP

Finalising commissioning#

  • Ensure the charger has connected to the new Wi-Fi AP (the LED should rapidly be blinking white)

  • Disconnected the charger from power

  • Set the current rotary switch to its original position (e.g. refer to the photo you took earlier)

  • Connect the charger to power

Commissioning Wi-Fi AP Credentials Using the Wi-Fi Captive Portal#

It is possible to commission the charger’s Wi-Fi AP credentials (SSID and password) by utilizing the Wi-Fi module’s built-in captive portal.

Notes:

  • This method can only be used if the charger is provisioned to use Wi-Fi

Instructions#

Bringing up the Charger’s Wi-Fi Access Point#

  • Ensure the charger is disconnected from power

  • Take note of the charger’s current rotary switch position (e.g. take a photo)

  • Set the charger’s current rotary switch to position 0

  • Connect the charger to power (you will see LED blinking white)

  • Wait for 30 seconds to allow the charger finish initializing itself

  • Hold any NFC card against the charger for at least 5 seconds

  • Scan for Wi-Fi APs on your phone/computer until a Wi-Fi AP with SSID equal to the charger’s serial number appears

Access the Wi-Fi Module’s Captive Portal#

  • Connect your phone/computer to the Wi-Fi AP hosted by the charger

  • Open a web browser and go to: 192.168.88.1/connect

  • Enter the new SSID & password for your AP

  • Click the Submit button

  • Wait for 30 seconds to allow the charger to reconfigure itself and connect to the new Wi-Fi AP

Finalising commissioning#

  • Ensure the charger has connected to the new Wi-Fi AP (the LED should rapidly be blinking white)

  • Disconnected the charger from power

  • Set the current rotary switch to its original position (e.g. refer to the photo you took earlier)

  • Connect the charger to power

Switching from LTE or Wifi to Ethernet#

This is only applicable to amina M

It is possible to switch the chargers network interface from LTE or WiFi TLS to Ethernet. Notes:

  • It is not currently possible to switch back to LTE from Ethernet.

Prerequisites#

  • The charger must be provisioned for TLS.

    • LTE and Ethernet only supports TLS

    • WiFi supports both TLS and plain websocket.

    • If the csms-url is prefixed with wss, the charger is provisioned for TLS

    • If the csms-url is prefixed with ws, the charger is provisioned for plain websocket

Instructions#

  • Ensure the charger is disconnected from power

  • Plug in an ethernet cable to the chargers ethernet port.

    • For a transition to take place, the cable must also be connected on the other side to a device capable of negotiating an ethernet link. (The device on the other side of the ethernet cable must be powered on)

  • Take note of the charger’s current rotary switch position (e.g. take a photo)

  • Set the charger’s current rotary switch to position 0

  • Connect the charger to power (you will see LED rapidly blinking white)

  • Wait for 30 seconds to allow the charger finish initializing itself

The charger is now using ethernet.
