[Tinyos-help] Maximum packet data length

[João Paulo Amaro da Costa Luz Carneiro]

Hi,
Thanks for the link.
After some tests I could determine the following:

- The maximum message size I could have was 106Bytes (my message  
structure has 5 nx_uint16_t fields and one array of 48 nx_uint16_t).
- The message is only sent if DTOSH_DATA_LENGTH is set to a value  
between 114 and 242.
- If 243  <= DTOSH_DATA_LENGTH <= 347 send signals success, but  
senddone never occurs
- if 347 < DTOSH_DATA_LENGTH both send and senddone fail.

Can someone please explain me these results I'm experiencing?

regards,

Joao
