A PiconetA FHHS protocolIt comprises of a base band processor, a radio and an antenna . The base-band processor converts the data into signals, the antenna of another blue tooth device, within at least 30 feet distance, receives a transmitted signal in the air.
It uses a frequency hopping spread spectrum technique (FHSS) - which is one of two basic modulation techniques used in spread spectrum signal transmission. Frequencies are switched repeatedly during radio transmission to help reduce unlawful access or other means of telecommunications to cross paths and cause interruption

PIO8 is used to control LED indicating the status. It will blink after power on.PIO9 is used to control LED indicating paring. It will be steady on when paring is successful.PIO11 is used to set this two mode: AT command mode (if the pin is connect to 3.3V) or Automatic binding transparent data mode (if the pin is connect to GND). The AT command mode is used to configure some characteristics of the device (for example the Master, Slave or Loopback modes).*
