Connecting for HCI/WCI-2 & Logic Capture

To capture UART and logic data at the Bluetooth Host Controller processor interface using a wired connection:

Note: SPI and SDIO capture is currently not available.

  • Connect an HCI Pod to the bottom of the Sodera unit in POD 1 or POD 2.

  • Attach the HCI Flying Lead assembly to the end of the HCI Pod. The connector is keyed to ensure proper installation.

UART Capture Configuration

Successful HCI UART capture requires the following Pod connections.

Required UART Layer Connections
Signal Name Pin Wire Color Comment
TX 2 White Connect to the Device Under Test (DUT) TX pin.
RX 3 White Connect to the DUT RX pin.
VIO LVL 7 Red I/O voltage reference that designates the threshold for a logic level "1".. The VIO LVL minimum voltage is 1.65 Vdc. The supplied voltage needs to be the DUT logic signal level that designates a logic level "1". Some DUTs will have a VIO signal/tap. If a VIO tap is not available, use the DUT rail/power supply (Vcc/Vdd). If an I/O reference tap is a available, use that as the VIO LVL source.
GND 10 Black Either one of these pins can be used to connect the DUT ground to the HCI pod.
GND 11 Black

Logic Event Capture Configuration

Successful logic event capture requires the following Pod connections.

Required Logic Connections
Signal Name Pin Wire Color Comment
DIG 1 8 Green TTL logic input. Connect to the Device Under Test (DUT)
DIG 2 9 Green TTL logic input. Connect to the DUT.
VIO LVL 7 Red I/O voltage reference that designates the threshold for a logic level "1".. The VIO LVL minimum voltage is 1.65 Vdc. The supplied voltage needs to be the DUT logic signal level that designates a logic level "1". Some DUTs will have a VIO signal/tap. If a VIO tap is not available, use the DUT rail/power supply (Vcc/Vdd). If an I/O reference tap is a available, use that as the VIO LVL source.
GND 10 Black Either one of these pins can be used to connect the DUT ground to the HCI pod.
GND 11 Black
