The radio used on the telosb is limited to total byte count of 128 bytes. The length field in an Active Message message is 8 bits so is limited to 256 bytes.
There are other limitations in the system due to available memory and other things but I haven't quantified them. TinyOS uses a static allocation scheme for most things. Dynamic allocation is available but isn't used as much because it opens the door to wild pointers and such. The best thing to do is to try out what you need and see if it works. eric On Fri, May 28, 2010 at 10:13 AM, chikh omar <[email protected]> wrote: > what is the size maximum of message send in tinyos? > > > *********************************************** > Omar Cheikhrouhou > **Engineer & Researcher @SENS Lab (Software Engineering and Network > Security) > Higher Institute of Technological Studies - Address : Mahdia's road Km 2.5 > Sfax.
