Hello everyone, Recently, I've just started working on TinyOS (using CC2420 telosB) and I have some questions that need your help as follows:
1/ I want to send a data message from node 1 to node 2 as MACA mechanism (using RTS/CTS/DATA msg). And node 1 should sense whether medium is free or not before sending any message. I used AMSend (AMSenderC) interface to send DATA msg: call AMSend.send(node 2, &pkt, sizeof(data_msg_t)) My question is that AMSend interface can sense medium (as CCA technique) and send RTS/CTS automaticlly before sending Data msg by default? Or there is another interface can do this requirement? 2/ What is the maximum size of package that telosB can support? 3/ I want to calculate the transmission delay (to make time synchronization between 2 nodes) and count power consumption of sensor node. Could you please suggest any solution on this? I'm greatly appreciate any great help! Thank you.
