NRF Connect startup errors, make worse with 2.7.0

[Thomas E.]

Hello,

I've been using NRF Connect on Windows for a 3 or 4 months now. During the startup I get a window that reads

Unable to download latest app info: Unable to download apps list: Unable to download developer.nordicsemi.com/.../nrf91.json. Got status code 404. If you are using a proxy server, you may need to configure it as described on https://github.com/NordicSemiconductor/pc-nrfconnect-core

But I was still able (with 2.62 and 2.60) launch BlueTooth Low energy, but now with 2.7.0 I cannot do that

Cannot read property 'number' of undefined

is the only message I get in an error box. I've updated J-Link to the latest on Segger's site. I am not using a proxy server.

thanks,

thomas

Hi, 

Could you open nRF Connect? What is the version now, v2.6.2 or v2.7.0? 

Click Add/remove apps to install apps or update existing apps.

v2.7.0 needs J-link v6.44e. Please check and update the J-link firmware version.

Or you can uninstall and revert back to stable v2.6.0.  

Best regards,

Amanda

Thank you for your response.

I went into {user}/AppData and removed everything that has *nrf*connect in the name. And was able to perform the installation of 2.7.0 and upgrade the applications.

With removing the evidence, I killed the ability to go back and root cause the issue. I am sure there was a configuration file that had an incorrect or old value.

thank you again,

thomas
