• Core Specification (10.3 MB pdf) of the Bluetooth System, Version 1.1, February 22 2001, copied from bluetooth.com
• Profile Specification (4.3 MB pdf), part 2 of above
• Specs. Overview
  • Frequency: 2.402-2.4835 GHz, divided in 79 1MHz-channels (23 in France, starting at 2.454)
  • Transmission power: 1-100 mW, range ~10m
  • channel hopping combats interference and fading
    • using pseudo-random hopping pattern (one of 10)
    • slot length = 625µs => 1600 hops/s
    • packets span 1-5 slots, usually only 1
  • Packets
    • In bits:
• All characteristics described in detail in their respective layer of the protocol stack
• Subsets of the protocol stack are grouped according to applications in profiles.
