The description in KW41Z datasheet:
Bluetooth v4.2 Low Energy compliant 1 Mbps GFSK modulation supporting up to 2 simultaneous connections in hardware.
What does this mean?
It means when KW41Z is a central role, it just can connect to 2 peripherals simultaneously, right?
If KW41Z is a peripheral role, could it connect to 2 other device(central or peripheral) simultaneously?
