This feature describes a new web app that is designed to work with a special toolkit, which enables users to update their stock nodes (SN3) to the latest firmware through an easy-to-use web UI.
...
Contact ORT to check if the portable (offline) Gateway is updated with the latest version.
Make sure to power off any other gateways within the communication range. This is mandatory to force all the nodes to connect to the offline gateway only.
Please make sure the laptop/computer is always ON during the Upgrade.
This toolkit is designed to upgrade 126 SN3s only (63 nodes per power jig) through one gateway at a time.
Offline OTAP process can only support upgrading the sensor nodes to firmware version 186. It is currently unable to support any Wirepas 5 updates.
| Note |
|---|
Please note that the gateway will not be able to distinguish between nodes powered on at the jig or installed in a luminaire. As long as there are nodes powered on and in reception range to form network and can see this gateway they will appear in the node scan. It is always recommended to ensure the number of nodes on the jig match the nodes that appear in the node scan. |
...
The power jig has 7x18 probe pins, which can power 63 SN3s at a time. Make sure you do not connect the mains’ power to the power jig when you are seating SN3s.
...

|---|
Caution: Please pay attention to the correct direction when you are seating the SN3, as in the picture below, and make sure to seat the node gently, just need a little bit pressure, avoid pushing it too hard, otherwise you may break the connectors of the SN3. A good practise would be to start from back line so that you can visually confirm the sensor node red dome and green led blink to indicate that they are powered on. |
This is what it looks like when all SN3s are seated.
...
Another angle is shown below. All 63 SN3s are ready for upgrade, and you can connect the mains’ power to the jig now.

Note: Please place the power jig on a stable bench and avoid moving the nodes during the upgrade process. |
3.1 Instruction to place the Detached Sensor Nodes (DNS) on Power Jig
...
The power jig has 7X18 probe pins, which can power 63 sensor nodes at a time. Seat the connectors to the probe pins as shown below, 9 connectors are seated to the pins, and you can seat up to 63 connectors.
| Info |
|---|
Note: Please do NOT connect the mains’ power to the power jig while you are seating the connectors. |
...
| Info |
|---|
After seating the connectors, you can connect the wires to the connectors. Please pay attention to the correct direction when you are connecting them. The red wire should go for the pin that has two pads nearby, shown with a red circle in the picture below. Make sure the wires are in good contact with the connectors. |
This is what it looks like when some DSN3s are connected. Of course, you can connect more.

HOW TO SCAN NODES | |
Action | Result |
| Node scanning is started and displays the progress indicator and number of nodes found once scanning is completed. The scanning process might take up to 10 minutes. (Figures 13 & 14) |
2. Click on the burger menu in top left corner | Detailed scan information is displayed below which consists of node details (Node ID, PIC and Nordic versions, BLE status) and logs. (Figure 15) |
...
Click on “All” to run a full firmware upgrade (Updater, PIC and Nordic, in that sequence) as shown in Figure 14.
Click on “Nordic Only” if you wish to run a Nordic upgrade only.
If you are upgrading the stock nodes, toggle on the “Reset Nodes to Factory defaults” to reset the nodes to their factory settings when the upgrade process is finished.
| Info |
|---|
Note: Please make sure to disconnect (unplug) all the nodes immediately after the upgrade process is done (no more than 15 minutes) to maintain the validity of the Automated Self-Test Sequence |
...
Wait until the upgrade process is completed. The upgrade process might take around 2 hours to be completed depending on the number of nodes.
Click on the top left corner menu “Advance mode” and then select the “Upgrade Nodes” column to monitor the upgrade status and to view the logs for each node.
The status of the Updater, PIC and Nordic for each selected node will be displayed as a color indicator as shown below,
Yellow - The process is initiatedOrange - Upgrade is in progress
Green - Successful upgrade
Red - Unsuccessful upgrade
Examples can be seen in Figures 19, 20, 21 and 22.
...
The UI allows you to control the BLE scanning for the scanned sensor nodes. Click on the left-hand side menu for the nodes to perform the following functions (Figure 26),
Get BLE status: Displays the information about the current BLE status (Blue means ON, Grey means OFF, a Question mark means the query is under process).
Turn on BLE scanning: turns on BLE scanning of the node manually.
Turn off BLE scanning: turns off BLE scanning of the node manually.
...
| Info |
|---|
Note: The BLE scanning will be automatically turned off for all selected nodes when the upgrade process is started and it will turn back on automatically once the upgrade process is completed. |
