Step 4. At this time, the APP will automatically generate a QR code picture that records the WiFi information. As shown in the figure below, please place this QR code about 20 cm in front of the camera. Waiting for a long beep from the buzzer means that the QR code information has been read, and you can remove the phone at this time. Wait for the buzzer to beep three times in succession.

If the WiFi indicator keeps on, which means the connection is successful, and if it is off, the connection fails.

If the connection fails, please check the QR code information and router signal, and then long press the K1 button again to enter the network configuration mode and reconnect.

3、Precautions

① The WiFi network configuration function of the camera can only be used when the Transbot APP process is started normally.

② If Transbot is currently connected to a WiFi network, and then use the camera WiFi network configuration function, you can also switch the WiFi network normally, but because the IP address needs to be assigned before ROS is started, some functions may be abnormal, please restart Transbot.

If the QR code WiFi information is wrong, it will cause the new WiFi network connection to fail and automatically connect back to the original WiFi network.

③ Please do not have Chinese or special symbols in the WiFi signal, otherwise it may cause abnormal connection.
