Notes
(1)
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) 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 nRF52832, periodically trimmed by S-device
(8)
TX power as set by AT command
(9)
Effective Data throughput lower due to flow control in older FW versions

lower current consumption S
