...found duplicate at Puck.js v1 on 2V16 - magnetometer not recognised...
Search is really not working in forum, and googling was not of much more helpful...
(using 1v14 until 2v17 will be out)
Yes, sorry for the problem.
Since I'm on holiday after today I'd rather not do another firmware release until the new year in case it were to introduce new issues.
I updated a Kickstarter Puck.js w/ most recent FW 2v16 using online Web IDE. Running the default code
complained in the console:
(Definitively not a battery level issue...)
After installing from url 2v00 - the oldest listed on the site for previous versions http://www.espruino.com/Download - above code works.
*) Looks like 2V14 is last one that works... (worked thru 2v06, was on before update, then 2v11, then 2v14: all ok; 2v15 shows same issue as 2v16).
