[Server-devel] Collaboration XO-1 with XS

2012-04-26 Thread David Leeming
I have noticed when using the combination XO-1 build 883 , Sugar 0.94.1 and
XS-0.6 that collaboration for registered XOs connected to the XS network is
unreliable. After doing some collaborating sometimes the populating of the
neighbourhood views becomes unreliable and shared activities are not
displayed on other XOs neighbourhood screens. Also, when hovering over some
XOs which are displayed on neighbourhood view, the name is not shown but
instead a long text stream. This has been attempting to disrupt teacher
training I am conducting but we work around it by for instance using
"discard network history" which seems to help.

 

I am copying to both lists as I am not sure where the problem lies. Any
advice appreciated and apologies if some of this has been covered in past
discussions, if so just a referral would be most appreciated.

Yep, we need to monitor our battery load, depending on the hardware we
could have the power info. I don't know about the FITPC, but we could
set up something quickly.
Or we use an analog input in relation with our electrical power,
define a range in which we should poweroff the board…
The best should be to have a small device, idle quite all the time,
sending a shutdown ip frame to the board when the load is critical
(too low or too high?)

I had applied for one for just this purpose back in mid February and only got 
an automated RT email and nothing else. 
I will send you a separate email with the RT id.
