Bootstrapping - u-blox EVK-JODY-W3 User Manual

3.4 Bootstrapping

JODY-W3 supports the following host interface combinations:
• PCIE-UART mode: Commands and data for the Wi-Fi traffic are transferred through the PCIe bus
to the module. The Bluetooth traffic uses the high-speed UART interface.
• SDIO-UART mode: Commands and data for the Wi-Fi traffic is transferred through the SDIO bus
to the module. The Bluetooth traffic uses the high-speed UART interface.
• SDIO-SDIO mode: Commands and data for both the Wi-Fi and Bluetooth traffic is transferred to
the module through the SDIO bus.
DIP switch SW503 is used on the EVB to define the boot mode and the physical interfaces used for
Wi-Fi and Bluetooth communication. Set each switch ON to pull the configuration signal low (GND,
logic level "0"), and OFF to pull it high (logic level "1").
Figure 11: Boot and host interface configuration
Table 8 describes the DIP switch positions for configuring the boot mode and host interface options.

The UART interface for Bluetooth can be accessed either directly through J305, or through the
USB type-C connector J205 and USB-to-UART bridge. For further information about the
Bluetooth UART interface, see also

Driver/firmware support for SDIO-SDIO is currently not productized.
