UART-CTS#, IUR-IN#, UART-RXD driven to CMOS high level, all UART output lines left open
(2)
connection parameters are setup by the central device when connection is established
(3)
no data to be transmitted, central device sends an empty packet (80 bit) then peripheral device
answers (empty packet: 80 bit)
(4)
these are a typical connection parameters used by an iPhone, iPad or iPad mini device in the
central device role
(5)
UART-inputs connected to GND or VSUP; UART output lines left open
(6)
same current consumption w. internal or external slow clock
(7)
RC oscillator internal to nRF51822, periodically trimmed by S-device
(8)
