4 years ago Let me clarify the QTrobot WIFIs and web interface. As it has been explained in different places (#7) QTrobot has an RPI and one NUC PC.
RPI WIFI is configured as Hotsopt with unique ssid for each robot (e.g. QT100). the web interface is accessible via http://192.168.100.1:8080 NUC WIFI is free and you can use it to connect to the internet either via it's Ubuntu desktop, terminal programs via ssh or using NUC web interface via http://192.168.100.2:8080 The reason that web interface of RPI does not allow you to change its WIFI configuration is intuitive: you cannot access it remotely any more via its hotspot! QTrobot gave you three simple options to connect it to the internet:
Using NUC WIFI Using an external WIFI dongle attached to RPI USB port (back of the robot) Using external Ethernet adapter attached to NUC USB-C port (see the attached picture) Notice: It does not matter which option you use to connect the robot to the internet. The internet will be always shared and routed between RPI and NUC!
Notice: If you connect external WIFI dongle to the RPI 's USB port, you need to reboot the robot and then it will be shown up in the RPI web interface!
Do you have a diagram for the QTrobot network available somewhere?
I think I understand the networking (ethernet-ish/WiFi between RPI and NUC and then separate WiFi on the NUC that shares internet between the two?), but it would be helpful to understand better, especially if we try to do something like connecting a USB-C to ethernet adapter to the robot.
