EUT Control Interface
RS232 HCI commands The EUT control interface provides RS232 HCI commands to the
EUT through a standard RS-232 interface. The interface meets the
requirements of the Bluetooth specification for HCI UART transport
layer. A RS232 cable is supplied.
USB HCI commands The EUT control interface provides USB HCI commands to the EUT
through a standard USB interface. The interface meets the
requirements of the Bluetooth specification section H:2. A USB
cable is supplied.
USB->RS232 HCI
commands
For use with EUTs fitted with USB->RS232 FTDI chips.
2-Wire control For test control of Bluetooth low energy devices the EUT control
interface supports the 2-Wire specification
