Overview

Radio

  • 2 modulation mode: 1. Basic Rate with GFSK (Gaussian Frequency Shift Keying); 2. Enhanced Data Rate with PSK(π/4-DQPSK and 8DPSK)
  • Power control is optional. Devices with power control capability optimizes the output power in a physical link with LMP commands (see Link Manager Protocol). It is done by measuring RSSI and reporting back if the transmission power shall be increased or decreased if possible.
