Mobile and Embedded

I enabled "USB debugging" and "Wi-Fi debugging". But how does the "Set up Wi-Fi" button work? I tried to press it, but when I disconnect the USB cable, the connection is lost. [image: 506f63f0-b6b1-4ac2-9c01-e9e0efdab9fe.png] I tried the commands from the post above but it doesn't work: E:>adb devices List of devices attached 099284036J008264 device 192.168.1.65:5555 offline E:>adb tcpip 5555 error: more than one device/emulator E:>adb connect 192.168.1.65:5555 cannot connect to 192.168.1.65:5555: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

@sanket_1989 said in QT 5.15 - ToradexIMX8mp: While running the application in different screen its cant adept the screen size runtime Are you using layouts? "it is open in new window instead of in QGraphics view" - show your code and also tell us what OS and window manager is running on your board.

@Nekk I meet the same situation on Yocto Kirkstone for iMX8.

I caused the problem myself: Check for details Not sure if anything I learned applies to you.

@esnosy said in Unable to debug Android App (Windows + Qt Creator 12 + LLDB): EDIT: I take it back Does that mean, you are still struggling?

@jsulm Thank you for your confirmation. AI, whether it's GPT-3.5 or 4.0, cannot distinguish whether it is referring to Qt 5 or Qt 6, which is really frustrating!

Anyone has any idea?

Never mind.. This is, apparently, the same issue as https://forum.qt.io/topic/143745/qtvirtualkeyboard-fails-on-embedded-buildroot-5-15-8. Switching from GCC 11 to GCC 10 "fixes" the issue.

@aashishqt You're welcome to enable eglfs, in your local.conf add DISTRO_FEATURES_remove = "X11 wayland" then in qtbase_%.bbappend add PACKAGECONFIG_append = " eglfs" qtbase_%.bbappend is found in meta-qt5 under recipes-qt, qt5 folder.

@Kaijun said in yocto build on qtxmlpatterns failed on Qt5.11: When I built qtxmlpatterns with yocto for arm, it failed with following messages, has anyone experienced this issue?

@Tahar it is likely, yes.

Hi, To complement WikiManiac's answer, I have recently re-discovered pyqtdeploy. Although there is documentation online about pyqtdeploy, it is hard to figure out specific steps to set up the tool. I have decided to update the documentation and upgrade a bit the tool on my side first. If you wish to convert your PyQt5 apps into Android apps, follow the in-depth tutorial on https://github.com/achille-martin/pyqt-crom. There is no official support for PyQt6 in my repo yet though. So please start with PyQt5 to build prototypes and I am expected to add support for PyQt6 later.

Update : i changed os from Raspbian Bookworm to Ubuntu 23.10 and i can display Webpage without any error! Conclusion: bookworm was the cause and not wayland

I found the solution. Add android.permission.POST_NOTIFICATIONS to AndroidManifest.xml. This is a requirement as of Android 13.

@ansh1234 said in I have a problem in building a file: E:sdkndk21.3.6528147/toolchains/llvm/prebuilt/windows-x86_64/bin/clang++ Is this path valid (if you add missing slashes)?
