Wifi Access
The Gateway supports WiFi Protected Access (WPA) and WiFi Protected Access II (WPA2)
802.11 wireless authentication and encryption standards. Detailed instructions for
configuring wireless access is available www.ursaleo.com/gettingstarted. Only wired or
wireless access is supported. Once configured the Gateway automatically establishes a
connection to the cloud and begins sampling the sensors and transmitting data. Readings
will start appearing in the specified 3D model a few seconds later.
LED debug
UrsaLeo provides an LED debug board that can be used to indicate the status of the
Gateway. The following LED conditions are available
● LED 1 on - system clock has updated time/date from NTP server
● LED 2 on - data is being received from the Thunderboard
● LED 3 on - MQTT link is established withmGoogle Cloud
● LED 4,5,6 are reserved for future use or for developers
● All LEDs off - clean shutdown, power can safely be removed
Thunderboard reset
The Thunderboard stops advertising after 30 seconds (before the Gateway finishes booting
for example). It is good practice to press the small black reset button on the TB2 after
boot-up and at regular intervals.
