[Tinyos-help] b6LoWPAN - telosb - IPBaseStation - serial_tun - problems

[Leon Steenkamp]

Stephen,

I am not using vmwear so i guess its not that. I fiddled around a bit 
and it looks like it is working now. I changed one or two things so I am 
not sure what exactly solved it (I'll have to investigate a bit more), 
but seems fine now so this is for historical purposes :) . I used a 
'Moteiv tmote sky' as a basestation mote, I swopped that to a 'MAXFOR 
TIP-700CM' in case it was a hardware problem and then for good measure I 
started the serial_tunnel with a "nohup" at the front and a "&"  at the end.
