nrf connect desktop app blank screen

[gorazd]

I have read the related issues, none of them provided a solution for me. There was one answer which suggested to downgraded libstdc++6 as a solution without giving any specific instructions on how to do that, what version etc.

So, the 'Bluetooth low energy app' is suddenly starting with blank screen after trying to flash the firmware at the start. Other apps work fine (e.g. power profiler).

I am on Ubuntu 22.04.2 LTS 64bit using nrfconnect-4.1.2-x86_64.AppImage, nrf-command-line-tools_10.23.0_amd64.deb

I would like to use the app to perform dfu upgrades. I also tried that with nrfutil (nrfutil 7.1.0 (c86ddc2 2022-11-29)):

nrfutil device program --firmware dfu_mtk_v0.11.3_7b555.zip --serial-number 1050312843

gorazd@gorazd-Victus-by-HP-Laptop-16-e0xxx:~/Programs/nrf-rust/firmware$ nrfutil device program --firmware dfu_mtk_v0.11.3_7b555.zip --serial-number 1050312843

Hi, 

I have asked the developers regarding question 1

Regarding question 2. Do you have https://github.com/NordicSemiconductor/nrf-udev installed?

hi,

number 2 i found the solution on forum (port flag should be explicitly given, snr is not enough):

nrfutil dfu ble -pkg dfu_edh_0.11.4_for_testing_purpose.zip -ic NRF52 -n DfuMTK -p /dev/ttyACM0 -f

Problem 1 still persists.

Thanks for the update. 

Are you able to run BLE app with verbose logging on and share the log? You will find the option in the about tab in the BLE app

Regards

That's what im able to collect with a copy paste. After 2 seconds the blank screen appears:

At some point i was able to get also the following log, but in that case no blank screen appeared, but application still did not go through.

Thanks, do the blank screen happen just after selecting device, or does it happen before?

[gorazd]

just after selecting the device

[runsiv]

Thanks

Could you try to open the app an then disconnect and reconnect the device and then select it and post the logs?

Sorry I forgot to post my replay earlier. Thanks for the logs, I'm awaiting feedback from the developers and will update as soon as they get back to me

Hi, 

The supported version with the app should be

JLink_V7.66a. The developer has also tested with JLink_V7.80c. Can you try if this works for you?
