Hi all,  Where can I find information about the scheduler in TinyOS1.1-x? How it works, queue size.. priorities..? I've been working with some Mica2's (and the dot's) in doing some ADC's measurementes and sending them off as quickly as possible. The problem is: apparently my motes are hanging because my scheduler is not able to dequeue tasks from the stack in enough time than new ones arrive.THis overflows the task queue and it freeezes completely. I found the following link which explains  what may be hapenning in my case as well, whose patch was submitted (this is exaclty the point where I am working with):http://mail.millennium.berkeley.edu/pipermail/tinyos-commits/2004-August/004891.html However if I follow his fix, it may decrease my bandwidth.. (which is exaclty the one that I want to pump up now!).Cheers,Edgar Charry
