[Tinyos-help] Problems with Tinynode and TinyOS-2.x

[Maxime Muller - s h o c k f i s h /]

Dear Jeremy,

i can reproduce this behavior for payload lengths of 10 and 25, the 
other lengths should be fine.
could you check that on your side?
something like
#include "message.h"
...
if (call AMSend.send(AM_BROADCAST_ADDR, 
&packet,counter%TOSH_DATA_LENGTH) == SUCCESS)
for a quick test.

ill have a look at what's happening for those 2 lengths.

Regards,
maxime
