[Tinyos-help] [Tinyos-devel] DelugeT2 and MIB600, serialforwarder

[Vincent Borrel]

Basically I stopped trying using deluge T2. I couldn't get past  
injecting an image. Disseminate or disseminate and reprogram couldn't  
be got to effectively do anything useful.

I quit losing my time on that one after 2 all nighters. That's been  
far more than all the time I could spend exchanging motes for my  
project, and I feel like having wasted a lot of time with that superb  
tool.

If someone got the magical procedure to make Deluge T2 work, could  
they please indicate me the correct shaman sequence of sorts ?

OK, rant over, back to work ;).

Vincent.
