How to add app sources on nRF Connect v3.3.1

[Aijiapeng]

Hi Dears:

   When I downloaded and installed nRF Connect v3.3.1, the following screen appeared.

  I remember when there was a drop-down box to select the BLE component.

  But it is not available now. How can I add app source?

  In addition, my working environment is windows10

Hi,

The app source is already added when you have installed the program so you have been presented with a list of available apps. Are you getting any warning messages when you open nRF connect?

eg message you may get if you are behind a firewall

Yes,i got the same message as you showed when i used nRF Connect v2.1.0.But i got none message when  i used nRF Connect v3.3.1.In addition, I have turned off all firewall related Settings on my computer.

Hi,

To confirm it's not a network issue, please try to see if you can access this URL in your web browser https://raw.githubusercontent.com/NordicSemiconductor/pc-nrfconnect-core/master/apps.json.

Hi，Vidar Berg：

  unfortunately, I accessed through browser to access this web site is not successful, even visit http://raw.githubusercontent.com is not successful.Therefore, I suspected it was my DNS, so I changed my host file in the directory C:\Windows\System32\drivers\etc.I added the following at the end of my host file.

199.232.4.133 raw.githubusercontent.com

Now I can visit https://raw.githubusercontent.com/NordicSemiconductor/pc-nrfconnect-core/master/apps.json for success. And nRF connect is finally working.I have downloaded the BLE module and everything is back to normal.

  Thank you, Vidar Berg!

Thank you for sharing the solution to this. I'm not sure what's preventing the DNS lookup, but I will make sure to relay this information to the team.
