Upload firmware using TN100 application
When using the TN100 Application, only one board may be updated at a single time. This is
due to the fact that the Gateway is connected by the serial cable to the host PC and each
board has to become a Gateway (only once) just for the time required to download the
firmware.
To upload a new firmware version using the TN100 Application, follow the steps below:
1.
Make sure the Gateway and the TN100 Application are switched on and working.
2. In
the
Sensing and Control
view, right-click
Gateway
and select
Upload firmware

The upload process will start, the Uploading firmware dialog will appear and, meanwhile,
LEDs LD2, LD3, and LD4 will be flashing in sequence indicating correct packet reception. At
the end, the sensor board will restart and LED LD1 will start to blink continuously again.
To upload the firmware to the other board, switch off the one currently connected and unplug
the serial cable. Arrange again the connections and switch on the board to be updated.
Once the node appears as Gateway, perform again the steps listed above. At completion,
both the sensor boards are updated with the new firmware and can be used again.
