[Tinyos-help] max length of message

[Faisal Aslam]

I think the maximum will be 256. It is because according to TEP 111 the 
length field is one byte long. However, in practice you might not be 
able to send packets that long because of RAM constraints.
By default it send packet of payload length 28. You can increase it by 
setting TOSH_DATA_LENGTH at compile time.
I suggest do not change it at runtime but only compile time.
In your application Makefile add CFLAGS += -DTOSH_DATA_LENGTH=110 to 
increase length to 110.

best regards,
Faisal
