NRF Connect displays only a white screen after some time.
I can connect to my nrf51DK with the ble or the PPK app, but after some seconds (changes between 1-20) only a white screen is displayed.
If I start the DevTools (ctrl+shift+I) it says "DevTools was disconnected from the page".
I can do a reload (ctrl+r) and everything looks ok, but can't connect to the board. I have to unplug it and connect it again.
What could be the reason for this behaviour? nrfconnect 2.3.0 did not have this issue.
We are not aware of anything, I will report it internally. Let me know if you have any new findings.
Is there anything I can help with debugging? Unfortunately there is no output on the dev-console and also no output on command line.
Additionaly to the white screen problem, it looks like the RTT connection is very unstable. If nrfconnect stays running I usually have to connect to the PPK multiple times until it is working. "Failed to open RTT channel"
If you have a package called "modemmanager" installed,uninstall it. It sees the /dev/ttyACM0 device and tries to send AT commands to it.
If you have the possibility and time you may build nrfconnect-core to get debug in console:
