When I receive a messagge using interface Receive with tinyos 2.1 I use the event event message_t * Receive.receive(message_t *msg, void *payload, uint8_t len) to save or elaborate what I have received using void *payload but what happen when I receive a new message ? The previous void*payload is rewrite . If I save the pointer void*payload as void *pay=payload and I use that (pay) I think that I don't have the problem of rewrite of the pointer but payload is a pointer and so it points to the same position ?so when I receive a message I must save the pointer pyload but it is better to save the contents of the pointer because that content is rewrite everytime a message is received ? Any suggestion is important for me. Thank in advance
