We've had a number of people mention that they were not able to get BerryLan to properly setup wifi. 

A possible solution is available from @GWLanger here; http://www.livesectional.com/community/postid/1269/

Here's the heart of his post;

So, I went into the bluetooth settings and edited the timeout for discoverability to 180 seconds.  

sudo nano /etc/bluetooth/main.conf

and editing the 'DiscoverableTimeout = 0' line to 'DiscoverableTimeout = 180' (Also uncomment by deleting the '#' sign.)

Then I restarted the bluetooth service:

sudo systemctl daemon-reload
sudo systemctl restart bluetooth.service

Then I was finally able to use Berrylan to connect to the Pi and use the app to configure the wifi settings.  I rebooted the pi and now it's been pulling the default weather info using the wifi for several minutes without issues.  

This fix has been incorporated and will be released in version number v4.383 and beyond. Also, starting with version v4.382 the issue with the log files has been corrected. Hope this helps and thank you @GWLanger. - Mark
