3 CONNECTING THE BRIDGE TO A WI-FI NETWORK
2. Choosing a Wi-Fi access point.
Although the Wi-Fi Bridge has a powerful radio, it conforms to international standards for EMI emissions,
which limit the maximum radio power that can be used. That being said, the maximum recommended distance
between the Wi-Fi Bridge and the Wi-Fi access point it will connect to is 50 meters on an unobstructed area.
Walls and other large metal barriers will reduce the Wi-Fi range. Ideally, the Wi-Fi Bridge should be placed on
top of the oven.
IMPORTANT: In order to use the Temperature Logging function and to evaluate its License status,
the Wi-Fi Bridge must have access to a Network Time Server (ntp) on the internet. If the device is
not allowed to connect to “ntp://us.pool.ntp.org” or “ ntp://ntp1.aliyun.com ” (Chinese builds)
another time server on the local network must be provided by the DHCP server.
3. Connecting to a Wi-Fi Access Point for the first time.
To configure the Wi-Fi Bridge to connect to an Access point, the following procedure should be used:
If there is no Access Point name pre-programmed on the Wi-Fi Bridge, or if it cannot connect to a previously
configured Access Point, the bridge enters Wi-Fi Setup mode: It starts its own Access point and activates its
bright Red LED light. The installer should use a PC or cell phone and connect it to the Wi-Fi
bridge’s Access
Point, with SSID “ WBV-nnnn ”. The value of ‘nnnn’ can be found on a sticker placed on the Wi-Fi Bridge itself.
After connecting to the Bridge’s Access Point, open a web-browser and navigate to http://192.168.4.1 . A
configuration web page will be displayed. Click “Configure Wi-Fi ” to see a list of detected Wi-Fi networks.
Select the correct one for your installation and enter the Wi-Fi password. Click “Save” . The Bridge turns its
Access point OFF, reboots and try to connect to the new Access point. If connection fails, the bridge resets and
re-enable its Internal AP. If connection is successful, the Bridge will light itself Yellow and then Green.
