If my understanding of what you are doing is correct and you want to send packets of length TOSH_DATA_LENGTH, then the actual call to 'send' has to falsely state that the length of the packet payload is TOSH_DATA_LENGTH. (eg: call Send.send(ADDRESS, TOSH_DATA_LENGTH, &buf) as opposed to call Send.send(ADDRESS, sizeof(type_in_payload_t), &buf) )
Just setting the variable somewhere simply sets the maximum that a packet can be, (ie: to save ram if you have a pool of statically allocated TOS_Msg structs). Changing the value is AM.h will have no more effect than setting it in a Makefile as the definition of this is " #ifndef ". Alan On 19/04/07, Munaretto, Daniele <[EMAIL PROTECTED]> wrote:
Try changing the length in the AM.h file. It should be fine.

In order to change the massage packet size, I added CFLAGS += -DTOSH_DATA_LENGTH=64 to Makelocal After that, I want to know actually whether its size is 64 or not. I used tiniViz. When I debug using tiniViz, I can see '[4] Sent Message <BaseTOSMsg> [addr ] and so on. However, Length is always expressed 0xc. I used surge application for multihop routing. Help me!!!! This method is right?????? _______________________________________________ Tinyos-help mailing list Tinyos-help@Millennium.Berkeley.EDU https://mail.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
