In addition, the maximum message payload size (which determines the size of a message_t) is set at compile time by defining TOSH_DATA_LENGTH. The default is 29 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.
