Can you provide some other App download url, for people from China. To download the APP.
In China , people cannot visit google service.
You can download the nRFToolbox app and other app here. You can compile and get the .apk file.
However the nRFConnect app is not available (yet).
EDIT: I was wrong, the nRFConnect apk is available here. It's the same for other app, click on release and you can find .apk
