Automatic Wi-Fi ALIGN Corrections

The WIFIALIGNAUTOMATION command is provided to simplify configuration of a pair of NovAtel Wi-Fi enabled receivers, one acting as an ALIGN Base and one acting as an ALIGN Rover.

The ALIGN Rover, acting as a Wi-Fi Client, connects to the specified Wi-Fi Access Point and configures it as the ALIGN Base. Use the WIFIALIGNAUTOMATION command to configure.

WIFIALIGNAUTOMATION <enable_disable> <base_networkid> <icom_port> <data_rate> <send_heading> <interface_mode>

Where:

  • enable_disable turns the feature on or off

  • base_networkid is the network ID associated with the SSID of the ALIGN Base as previously configured using the WIFINETCONFIG command.

  • icom_port is the ICOM port to be used for ALIGN corrections on both the Rover and the Base. It is assumed that the Base's ICOM port is configured with its factory default settings.

  • data_rate is as defined in the ALIGNAUTOMATION command.

  • interface_mode is as defined in the ALIGNAUTOMATION command.

The term passkey and password are the same.

If this feature is enabled and the SAVECONFIG command issued, when the Client is searching for an Access Point (either after startup or if the connection is lost), it will connect to the Access Point specified by <base_networkid> even if another Access Point with a preferred network_id (as entered by the WIFINETCONFIG command) is in range.

If interface_mode is omitted, it is assumed that the ALIGN Base Access Point is already configured to transmit the desired corrections over the specified ICOM port.

Note that up to four rovers can be associated to the same Base, each using a different ICOM port.

Example:

Enable Wi-Fi ALIGN corrections using receiver SM7-NMND17190003B as the Base.

Using a serial port connected to the Client, enter the following commands:

WIFINETCONFIG 1 ENABLE SM7-NMND17190003B SM7_PWD

WIFIALIGNAUTOMATION ENABLE 1 ICOM5 20 ON NOVATELX

SAVECONFIG

Internally, the SMART7 client does the following:

  • switches to Concurrent mode if currently configured as an Access Point or Client

  • scans for available Access Points until SM7-NMND17190003B is detected

  • connects to the SM7-NMND17190003B Access Point

  • configures itself as follows:

ICOMCONFIG ICOM5 TCP 192.168.19.1:3005

INTERFACEMODE ICOM5 NOVATEL NOVATEL ON

  • sends the following commands over ICOM5 to the Base:

UNLOGALL ICOM5 TRUE

MOVINGBASESTATION ENABLE

LOG ICOM5 NOVATELXOBS ONTIME .05

LOG ICOM5 NOVATELXREF ONTIME .05

INTERFACEMODE ICOM5 NOVATEL NOVATELX

  • configures itself as follows:

INTERFACEMODE ICOM5 NOVATELX NOVATEL OFF

LOG ICOM5 HEADINGEXTB ONNEW
