int_ua, hello!
I ran charge21.sh (size 5840, md5sum d90c20072f9056dc2147e50427fbc0db) with i2cset taken from meegocharge.tar (from the same page). That gave 'right' answers from bq27200.sh (und - - power adaptor warm ) (did not try with USB yet, and do not know about precompiled i2c-tools - hopefully will work; And maybe - who knows - there are some other ready tools to access hardware in that sensors-package...)
