4.2. BT Overview
SC20 module supports BT4.1 (BR/EDR+BLE) specification, as well as GFSK, 8-DPSK, π/4-DQPSK
modulation modes.
Maximally support up to 7 wireless connections.
Maximally support up to 3.5 piconets at the same time.
Support one SCO (Synchronous Connection Oriented) or eSCO connection.
The BR/EDR channel bandwidth is 1MHz, and can accommodate 79 channels. The BLE channel
bandwidth is 2MHz, and can accommodate 40 channels.
