Software Features
xPico 200 software stack provides the essential IoT connectivity infrastructure for building
secure connected products. Device Manufacturers can offload this complexity from their
application microcontroller when interfacing with the module in Hosted Mode or use the
module as the wireless microcontroller in Host-less or Standalone Mode.
Hosted Microcontroller Mode
The module completely offloads all Wi-Fi and secure network connectivity requirements for
attached microcontrollers thereby reducing device firmware complexity while accelerating
OEM’s time to introduce and support secure connected products in the market. The host
interfaces available for connecting to the microcontroller are UART, USB, SPI and Ethernet.
Figure 2-2 Hosted Microcontroller Mode
Wireless Microcontroller Mode
In addition to these interfaces, xPico 200 series also offers additional interface such as I2C,
GPIOs and SDIO along with their control lines to support integration with other peripherals and
use as a wireless microcontroller in standalone mode. With the provided SDK, device
manufacturers can leverage not only network and wireless stacks, but also the complete
application framework that includes the configuration management system, reliable remote
OTA firmware upgrades, automated connection management features described below.

TruPort Serial
Robust serial to Wi-Fi and serial to Ethernet application that supports transparent transport of
hundreds of serial protocols over the network. TruPort Serial is very suitable for hosted
microcontroller applications with very little to no programming and development effort.
Key capabilities included are:
Support RS232 serial and USB (CDC Serial and CDC ACM Device Classes)
Advanced connectivity modes and configuration knobs to tune the connection parameters
for a specific protocol without requiring custom software programming
Automatic and Manual connect modes
Inbound (Accept Mode) and Outbound (Connect Mode) connections
Modem emulation mode enables connecting to different servers using a standard AT
command set
AES (128-bit, 192-bit, 256-bit) Encrypted session and TLS session modes for secure
tunneling
TruPort Offload
Connect your device microcontroller to multiple services and communicate directly with mobile
devices and cloud services at the same time via TruPort Offload. The simple API for TruPort
Offload is available via the UART or USB interface operating in CDC ACM mode.
Seamlessly switch between data mode and module management mode (CLI access) for total
control and data channel access from your device application microcontroller.
Access TCP, UDP, TLS, HTTP, SMTP channels and communicate with external services
through these channels without implementing these protocol stacks within your microcontroller.
xPico® 200 Series Wi-Fi® IoT Gateway module Data Sheet 11
TruPort Security
Device Manufacturers are exposed to new security risks that emerge with having connected
products. They also have to navigate the engineering complexity of providing integrated security
within their connected devices. Lantronix TruPort Security provides an integrated device security
framework that lets device manufacturers build this into their connected products from the start of
their design cycle instead of as an after-thought or bolted on component.
TruPort Security enables building secure connected products quickly and easily with a full range
of features including:
Secure Boot – run only signed software on device
Secure Connectivity – Enterprise Wi-Fi Security, Data-at-rest and Data-in-motion
authentication and encryption
Encrypted Storage – stored configuration and device data securely
Fine Grained Port Access Control – Prevent back-doors with fine grained control over
network ports
Root of Trust and Device Identity – Certificate Management, Secure Key Storage, OEM
Keys
Ethernet to Wi-Fi Client Bridge
For devices with microcontrollers that include a network stack and also have Ethernet
connectivity available, the Gateway module module software provides wireless connectivity to
these devices via the Ethernet to Wi-Fi Client Bridge mode. In this mode, the Wi-Fi stack is
fully offloaded and managed via the configuration interface. This mode is most suitable for
networked microcontrollers that do not have the resources to integrate wireless device drivers
and add-on the complexity of managing the wireless stack.
Enterprise Wi-Fi Security
Centralized control of security policies and ability to permit and revoke access rights and
scaling to support the large number of devices deployed within the enterprise are primary
considerations that Enterprise Wi-Fi Security addresses. With support for 802.1X, 802.11i and
EAP authentication methods along with support PKI support and X.509 certificate
management, connectivity to the enterprise network is handled via configuration and without
any integration, testing and certification of supplicant and authenticator software.
Wi-Fi Connection Profiles
Connect to multiple wireless networks autonomously by configuring the network parameters
once and then letting the module automatically select the best network to connect to or set
policies for connecting to specific networks. Wi-Fi connection profiles eliminate the need to
manage the state of connection management from the device microcontroller or writing this via
the SDK in wireless microcontroller mode.
Configuration and Management Interface
Access the module configuration and management engine via the microcontroller or via the
network. Command Line Interface (CLI) mode offers a text based interactive interface versus
writing an elaborate driver interface for the AT command and control interface on the device
microcontroller. XML and Web API offer the ability to program the module configuration via the
Over-The-Air (OTA) or Network interface. For more details on the usage of these management
interfaces, please refer to the xPico 200 Command Reference Guide.
xPico® 200 Series Wi-Fi® IoT Gateway module Data Sheet 12
Reliable OTA Firmware Upgrade
As device requirements evolve and new product features are provided, device manufacturers
can leverage the reliable OTA firmware upgrade capabilities to prevent “system bricks”. OTA
firmware upgrade always ensures there is at-least one known version of firmware available in
the event an upgrade operation does not succeed. It operates over the connected network and
does not require placing the module into specific operational modes into order to trigger the
update. Updates can be performed remotely and securely using the included Secure Boot
features.
xPico® 200 Series Wi-Fi® IoT Gateway module Data Sheet 13
3: Host Interfaces
The xPico 200 module offers a number of common interfaces to allow for easy connectivity to
the module. These include 10/100Mbps Ethernet MAC with RMII, UART for asynchronous
serial communication, serial peripheral interface for synchronous formatted data, and USB
host interface.
Ethernet
The xPico 200 module has an integrated 10/100Mbps Ethernet MAC and with an RMII
interface. External PHY, magnetics and RJ45 are required for connection to a standard
Ethernet network. See the xPico 200 Enterprise Wi-Fi IoT Module Integration Guide available
