I forgot to mention, I am using CORE. So in this case CORE will be sending the location events. I feel like a total newbie, though how can I debug or diagnose what's occurring under the hood? For example, I see the equations rxP ower = txP ower + txAntennaGain + rxAntennaGain pathloss AND rxSensitivity = 174 + noiseF igure + 10 log(bandW idth) though how can I actually view these values to help me judge how to tweak the configuration paramters?
