Can't connect to nRF52840-DK with Python CHIP Controller

user114952

Hi,

I have an issue in regard to Matter. I would like to commision a device in my network, but I don't know why the Python CHIP Controller returns this error every time I try to talk to the device:

chip-device-ctrl > connect -ble 3840 20202021
Device is assigned with nodeid = 171557

I followed the instructions from this video:

Has anyone encountered this same issue? Thanks!

    Hi

    I used it and it works, also used the "ConnectNetwork" instead of "EnableNetwork". However, when I try to run the "resolve" command (only with nodeid as parameter), it doesn't do anything other than quitting the chip-device-ctrl.... Is there a substitute for the resolve command also?

    Thank you,

    Hi

    I do not think there are any other command doing the same as the resolve command.
    Do you get any error message from the resolve command?

    Just so you know: As an alternative to the Python Chip Controller, you could try the chip-tool for Linux of MacOS.

    This is the output

    Hi

    This error looks like the one in case 84317.

    Try to follow the advise from Charlie in the case; Does it fix your issue?

    Regards,

    Hi

    So first, I checked the poste you shared with me, but it's the same as closing the ble connection and then running the resolve command, right? Which is exactly what I was doing...

    Second, can you please tell me what python version I need to have to be able to run the chip-tool, and also how much free disk space is needed?

    Thank you,
    Mihnea Cristian Marin
