Luckily, here is a buildroot project customized for raspberrypi. serial port communication with peripheral devices.fully customizing capabilities on kernel and user applications.My desired raspberrypi image should meet: Raspberrypi provides several images for downloading, but they are too large and exceeds my needs. I bought a raspberrypi to try some interseting ideas on. And I finally found that the connman package caused the conflict. I struggled a lot with the interfaces file due to the dhcp always failed to work.

Having tested the network run ok, I updated the /etc/network/interfaces file so that network would be setup automatically. So I can setup the network with commands below:
Qt5 serial port config raspberry pi password#
My wifi router, which is configured with dhcp server enabled, doesn't required password to connect. I enabled wireless tools in buildroot config, which provides tools such as iwlist, iwconfig. But in my case, I use a small system image built with built from builtroot with only command line interface, I have to setup manually. There is GUI based connection manager if you're using raspbian system image. The next step is to configure the dongle so that it can connect to my wifi router. So it just worked after I plugged it to raspberrypi. This dongle uses RTL8188CUS chipset, which has built-in support on the raspberrypi linux kernel. The raspberrypi has two usb ports, so I bought a usb wifi dongle to get rid of network cable.
