Connection Management tab

The Connection Management tab lets you configure the default TR50 connection between the gateway and the deviceWISE Cloud . It is also possible obtain the status of the default TR50 connection and several key statistics. This section describes the various components of the Connection Management tab:

  Parameter Description
1 Connection Name This panel will always list the configuration for the TR50 connection namedDefault . The Default TR50 connection is always defined for a gateway. Additional TR50 connections can be defined and configured using the TR50 Connections tab.
2 State Can be Started or Stopped. In order for the TR50 connection to be successfully established between the gateway and the deviceWISE Cloud , the State parameter must be Started and the Status parameter must be Connected.
3 S&F State Can be No profile defined, Forwarding, Storing, Standby, Ready to store, Storing - forced, or Ready to store - force. In order for Store and Forward to be active, a Profile must be defined. Once a Profile is defined, the S&F state will then rely on the State parameter or Toggle Forced Storing button.
4 Status Can be Connected, Connecting, Not connected, Disconnected, Broken, or Reconnecting.
5 Connect Time When the Status is Connected, the date and time that the connection was established. The duration of the connection is also shown.
6 Traffic Sent When the Status is Connected, the amount of data sent from the gateway to the deviceWISE Cloud . The first value is the user data sent. Then the total amount of data sent is displayed, which includes overhead for the TR50 protocol. The total data sent does not include all of the lower level protocol overhead; thus, it cannot be used to approximate the amount of data sent over a cellular connection.
7 Traffic Received When the Status is Connected, the value is the amount of data received from the deviceWISE Cloud . The first value is the user data received. Then the total amount of data received is displayed, which includes overhead for the TR50 protocol. The total data received does not include all of the lower level protocol overhead; thus, it cannot be used to approximate the amount of data received over a cellular connection.
8 Latency The time for a round trip from the gateway over the TR50 connection to the deviceWISE Cloud and back. This time gives an indication of the network response time performance.
9 TR50 Server Address
 		This is the HTTPS endpoint listed on the Management Portal -> Developer -> Applications page. An example value is api.devicewise.com.
10 Connection Type The options are:
  • MQTT - MQTT using TCP port 1883.
  • MQTT with TLS - MQTT encrypted with TLS/SSL using port 8883.
  • MQTT via HTTPS Proxy - Special connection that uses an HTTPS call on port 443 to establish a proxy connection for standard MQTT traffic.  You should use this option if you are behind a firewall and are not able to connect with either of the native methods.
11 Proxy Type If you are connecting through a proxy server, select the appropriate proxy type. The proxy type can be:
  • None
  • SOCKS4(a)
  • SOCKS5
  • HTTP
    Depending on the proxy type, additional input parameter become available for specifying the proxy server address, the user ID, and the password required by the proxy server.
12 Thing Key This is a deviceWISE Cloud wide unique hardware ID for this gateway. The Thing Key selection list options include values that are valid for this gateway, and may include the:
  • MAC address of the gateway's Ethernet port
  • Serial number of the gateway
  • Linux ID for Linux based gateways
  • Linux GUID for Linux based gateways that have dmi support from the BIOS

  • Windows ID for Windows based gateways

  • International Mobile Station Equipment Identity (IMEI) number of the gateway's cellular modem
  • (ICCID) number of the cellular SIM card inserted into the gateway
  • Custom
    The hardware ID must be unique for all gateways connected to the same deviceWISE Cloud . It is used in the deviceWISE Cloud registration process and must match the gateway's definition specified in the Management Portal if the gateway auto-registration function is not used. For more information about adding a gateway in the Management Portal, see Things.
  • Custom ID File
    It is possible to supply hardware ID through a file.

TR50 automatically downloads a license if the node does not have a license. The selected Thing key(hardware ID) is used to generate the license. If custom ID is used, license will be generated using the first hardware ID in the Thing key List. It is possible to change this behavior by specifying a property:
tr50.registration.default_hardwareid_type=#type#
For example: tr50.registration.default_hardwareid_type=Linux GUID
The hardware ID is different from one node to another. All the hardware IDs are listed in the Node Administration panel. The first hardware ID in the list will be used to generate the license.
13 Custom ID Available when the Thing Key option is Custom.
A custom (user entered) Thing Key. The valid characters for a Custom ID are: letters, numbers, "_" (underscore) , and "-" (hyphen).
  Custom ID Type Appears when Thing Key option is Custom ID File.
  • Staging: The file is uploaded to the Staging Browser.
  • System: The file is accessed through an absolute path.
  Custome ID File
  • When Staging is selected, provide the staging path to access the file. For example: /tmp/serialnumber.txt
  • When System is selected, provide the absolute path to access the file. For example: root@learning: ~/.local/share/ssmp.conf
14 Application Token The token (a string) from the Management Portal -> Developer -> Applications page that correlates this gateway to a specific Application (and Organization) in the deviceWISE Cloud .
15 Save Used to save the current values on the TR50 Connection Management tab.
The value of State must be Stopped for the Save button to be active.
16 Start Used to start the TR50 connection.
The value of Status will appear as Connected when the TR50 connection is successfully establish between the gateway and the M2M Service.
The value of Status will appear as Disconnected (along with an error message) when there is a problem establishing the TR50 connection.
The value of State must be Stopped for the Start button to be active.
17 Stop Used to terminate the TR50 connection.
The value of State must be Started for the Stop button to be active.
18 Clear Counters Used to clear the Traffic Sent and Traffic Received values.
19 Toggle Forced Storing Used to force store S&F capable data while the value of Status is Connected, and a Profile is defined.
20 Refresh Used to refresh all values on the TR50 Connection Management tab.

To change parameter values, the TR50 connection must be in a Stopped State. After any parameters have been changed, the current values should be saved using the Save button to retain them. Then the TR50 connection can be started again using the Start button.

Additional TR50 connections are managed using the TR50 Connections tab.
