comment = {Bluetooth Low Energy shares some similarities with Classic Bluetooth. Both use the 2.4GHz spectrum. Basic Rate (BR) and BLE both use GFSK modulation at 1Mbps, but their modulation index is different. Enhanced Data Rate (EDR) uses a completely different modulation than GFSK. Classic Bluetooth has 79 channels compared to LE’s 40 channels. The channels are also spaced differently. Both of these differences make LE and Classic different and incompatible, so they can’t communicate. Dual Mode Radios, like the Texas Instrument's CC256x or Corvo, support LE and Classic by switching their modulation parameters and the channels on which they’re running.},
