nRF Connect VS Code Extention

[Emre Bayraktar]

I'm having an issue while trying to install the nRF Connect vsCode extension. I assume that extension has auto board detection feature. However, on my computer, this feature does not work as expected. There is another device connected to my computer which opens a couple of virtual com ports. When I enable the nrf extension, it continuously opens and closes these com ports, making them unusable. How can I disable the auto-board-detection feature ?

Hi, 

Sorry for the confusion. I've successfully installed and uploaded code to nrf54L devkit. I'm also doing development on  Quectel's SoC's which connected via USB and creates seven virtual com ports for different purposes. I meant the Quectel's SoC by "another device". 

The problem arises when I plug in the Quectel device while the nRF Connect extention is enabled. Once connected, extention continuously opens and closes the com ports of Quectel SoC. Since its automatically does this open/close behaviour, I've assumed that nRF connect continously search through avaiable com ports to find a nrf board.

When you plugged in Quectel device, was any of Nordic devices connected?
How did you verify opening and closing of the ports of the Quectel SoC by the extension?

Best regards,

Hi, 

The problem continues even if I plug in a Nordic device. I've confirmed the open/close behaviour caused by extention since it only happens when VS Code is open and extention enabled. In this state, I cannot use the Quectel's com ports with any application. When I disable the extention, open/close behaviour immediately stops and com ports became usable.

Hi,

Is this issue reproducible just by running "nrfutil device --hotplug"?

Hi, 

The command returned error. Here is the output:

Hi Emre,

I have noticed that "list" was missing from suggested command. I apologize for this. Correct command is "nrfutil device list --hotplug". Is your issue reproducible using this command?

Best regards,
