[Commotion-dev] Boilerplate Android code pushed

Wed Jan 11 02:44:26 UTC 2012

A little bug report, in case you're interested:

I just downloaded Serval Mesh from the Marketplace on my Droid running CM7.1.  It gets thru "Unpacking the stuff I need", "Checking for root access", and "I think I know how to control your wifi", then says "Skipped check for experimental support since we already support your handset.", and gets stuck on "Test if WiFi control works".  It just seems to try again and again.
