Hello, I am using the active message abstraction on top of the TKN154 with telosb motes. I am basically testing the unslotted csma procedure, therefore I am using the protocol in a very simple scenario: non-beacon enabled mac, no-coordinator, indirect transmissions between devices (by broadcasting).
In this scenario, all nodes generate and broadcast data packets at certain rate (ranging from 10 pkts/sec up-to 50 pkts/sec). The problem starts after some time, when some nodes are not able to send packets anymore (send fails with EBUSY). It looks that after the last 'successful' AMSend.send , there was no AMSend.sendDone event. I tried to restart the MAC using MLME_RESET.request, it returns SUCCESS, but I never get the MLME_RESET.confirm. Every time I run experiments, the number of nodes that fail is different, and even some times there are no failures at all. I am using AMSenderC and AMReceiveC. When I switch to the normal MAC, everything works fine. Any help?
