Hi all Sometimes, I have to cancel a packet transmission at MAC layer and in this case, I want to send the packet to the routing layer again and store it in a queue to sending it later. I've been trying to make that at mcps_data_request method of p802_15_4mac.cc, just at the moment when the node should switch on the TX. The poblem is that my code isn't correct (I really don't know what to do) and I have an segmentation fault. Hence, I'd like to know how to implement this.
Thanks a lot
David
