Tips:
Q: Why there are 2 bars in most of the results?
A: That is because of the non-monotonic feature of LC frequency settings. Referring to the LC_count result above, each time the coarse increments, the actually LC frequency drops, resulting two bars on two adjacent coarse settings.
Q: Why there sometimes is another bar of outliers?
A: This is because of the abnormal behaviors of CC2538 chip that it receives frames from other channel rather than the one it listens to. By checking the signal strength of each frames received by OpenMote, the bar outliers responds to frames with low RSSI value (<-85dbm), while the other bars responds frames with RSSI value >-50dbm.
