nRF Connect, Ubuntu Gnome 17.04, blank window

Ladasky

Hello everyone,

I'm usually on the cutting edge with Ubuntu Linux. I upgrade my development box frequently, because I like the precompiled binaries in the Ubuntu repository. I prefer to use my time building nRF52 apps from source, rather than building Linux apps from source.

I just upgraded to Ubuntu Gnome 17.04. I also have nRF Connect v 1.1.1. I have a PCA10040 board connected to a USB port, to use as a BLE receiver.

I had everything working in 16.04, save for a mysterious, but apparently harmless, JavaScript error message which occurred when I closed nRF Connect (click here if you're interested).

On 17.04, nRF Connect starts up correctly. The Select serial port pull down menu shows my PCA10040 board attached to /dev/tty/ACM0. However, when I select that board, the whole nRF Connect window goes... blank.

Please advise, thanks.

    Database is not ready yet. Storing entries in queue for later storage in DB.

    Finally, when I try to connect to my PCA10040 board with the console log open, I see a popup window that was not visible with the console log closed. It reads:

    DevTools was disconnected from the page. Once page is reloaded, DevTools will automatically reconnect.

    Hope that helps. Thank you!
