Hello, I am trying to build a wireless sensor controller where the sensors are distributed and a central device is able to read the status of every node. My knowledge about wireless networks is novice at best. I was looking into zigbee and then got hold of TI's CC2500 development tool. I ran the demo but the distance from the sensor to the pc was too short for my application. I was abl...
