1.9 Data communication interfaces
TOBY-L2 and MPCI-L2 series modules provide the following serial communication interface:
USB interface: High-Speed USB 2.0 compliant interface available for the communication with an external host
application processor, for AT commands, data communication, FW upgrade by means of the FOAT feature,
FW upgrade by means of the u-blox EasyFlash tool and for diagnostic purpose (see section 1.9.1 for functional
description)
TOBY-L2 series modules additionally provide the following serial communication interfaces:
UART interface: asynchronous serial interface available for the communication with an external host
application processor, for AT commands, data communication, FW upgrade by means of the FOAT feature
(see section 1.9.2 for functional description)
DDC interface: I
2
C bus compatible interface available for the communication with external I
2
C devices as an
audio codec (see section 1.9.3 for functional description)
SDIO interface: Secure Digital Input Output interface available for the communication with an external u-blox
Wi-Fi module (see section 1.9.4 for functional description)
1.9.1 Universal Serial Bus (USB)
1.9.1.1 USB features
TOBY-L2 and MPCI-L2 series modules include a High-Speed USB 2.0 compliant interface with maximum data rate
of 480 Mb/s, representing the main interface for transferring high speed data with a host application processor:
the USB interface is available for AT commands, data communication, FW upgrade by means of the FOAT feature,
FW upgrade by means of the u-blox EasyFlash tool and for diagnostic purpose.
The module itself acts as a USB device and can be connected to a USB host such as a Personal Computer or an
embedded application microprocessor equipped with compatible drivers.
The USB_D+ / USB_D- lines carry the USB serial bus data and signaling, providing all the functionalities for the
bus attachment, configuration, enumeration, suspension or remote wakeup according to the Universal Serial Bus
Revision 2.0 specification [7].
The VUSB_DET functionality is not supported by all the TOBY-L2 modules product versions: the pin should
be left unconnected or it should not be driven high by any external device, because a high logic level applied
to the pin will represent a module switch-on event (additional to the ones listed in section 1.6.1) and will
prevent reaching the minimum possible consumption with power saving enabled.
The VUSB_DET pin is not available on MPCI-L2 series modules.
The USB interface is controlled and operated with:
AT commands according to 3GPP TS 27.007 [9], 3GPP TS 27.005 [10], 3GPP TS 27.010 [11]
u-blox AT commands
For the complete list of supported AT commands and their syntax see u-blox AT Commands Manual [3].
