Hi all,
How can a sensor node receive packets from another sensor node using Xmesh
(Crossbow) and TinyOS1? I read the material and I just saw the upstream
transmission mode using sink nodes, but I want a communication between
sensor nodes (source and destination). I changed the source
BASE_STATION_ADDRESS for the specific NODE_ADDRESS (ex: 1), but the code
doesnt work.
Thanks in advance.
