xPico® Wi-Fi® SMT Embedded Device Server Datasheet 14
Reflow Profile Guideline
The reflow profile is dependent on many factors including flux selection, solder composition, and
the capability of user's reflow equipment.
USI does not recommend a specific reflow profile but provides the following general guidelines:
♦
The solder composition typically sets the peak temperatures of the profile.
♦
Recommend lead free solder pastes SAC305: Type 4, water soluble or no clean are
acceptable.
♦
Reflow equipment needed at least nine heater zones. Recommend forced air type reflow
oven with Nitrogen.
♦
It is recommended that the peak temperature at the solder joint be within 235°C ~ 245°C
and the maximum component temperature should not exceed 245°C.
♦
It is recommended that time above 217°C for the solder joints is between 40-90s, and
with a minimum of 40s.
♦
Excessive ramp/cooling rates (>3°C/s) should be avoided.
♦
To develop the reflow profile, it is recommended that the user place thermocouples at
various locations on the assembly to confirm that all locations meet the profile
requirements. The critical locations are the solder joints of SiP Module.
♦
When developing the reflow profile, it is recommended that the actual fully loaded
assembly be used to make sure that the total thermal mass is accounted for.
(1) Solder paste alloy: SAC305(Sn96.5/Ag3.0/Cu0.5)(Lead Free solder paste is recommended by USI.)
(2) A-B. Temp.(Pre-heat): 150~200℃; soak time:60~120sec.
(3) C. Peak temp: <245℃
(4) D. Time above 217 ℃: 40~90sec.
(5) Suggestion: Optimal cooling rate is <1℃/sec. from peak to 217 ℃.
(6) Nine heater zones at least for Reflow equipment.
(7) Nitrogen usage is recommended and the oxygen concentration is controlled less than 1500 ppm.
Note: Need to inspect solder joint by X-ray post reflow.
xPico® Wi-Fi® SMT Embedded Device Server Datasheet 15
4: Host Interfaces
The xPico Wi-Fi SMT device server offers a number of industry common interfaces to allow for
easy connectivity to the module. These include UART for asynchronous serial communication,
serial peripheral interface, for synchronous formatted data and USB host interface.
UART
♦
The xPico Wi-Fi SMT device server supports two UART interfaces (UART1, UART2)
♦
Both UARTs support asynchronous data rate up to 921 Kbps, with Odd/Even parity, and
1 & 2 stop bits
♦
Software flow control (XON, XOFF) for both UART1 and UART2
♦
Modem control (DTR, DCD) pins for UART1 only. Enabled by device configuration as
pins are shared with configurable pins (CPs)
♦
Operational mode as a DTE device
♦
UART1 – supports TX, RX, RTS, CTS (hardware flow control)
♦
UART2 – supports TX, RX functions only. Hardware flow control is supported by using
software controlled configurable pins.

Input/Output (GPIO) pins. Certain of the GPIOs are multiplexed with other interface functions
(e.g. SPI). Mapping of these functions to CPs will be driven via configuration and applied at
system initialization.
Each CP can be configured as a general purpose input, general purpose output, microcontroller
peripheral block or a soft function (e.g. modem control). These pins are 3.3V CMOS logic level
and 5V input tolerant. For more information on how to use, configure and manage the utilization
of the available GPIO please refer to the section on Configurable Pins in the xPico Wi-Fi
Embedded Device Server User Guide.
Note: For xPico Wi-Fi 5V tolerant pins, in order to sustain a voltage higher than Vcc+0.3,
the internal pull-up/pull-down resistors must be disabled. Refer to the xPico Integration
Guide for more detail.

10: Software Features
Software Architecture Overview
The following represents the functional block diagram and architecture of the Lantronix xPico Wi-
Fi SMT family of embedded device servers.
The following features are provided with the xPico Wi-Fi SMT device server software.
Soft AP Mode w/ DHCP Server
The xPico Wi-Fi SMT device server has the ability of allowing up to four Wi-Fi clients to connect
to a Soft Access Point in a simple and standard manner. The SoftAP also includes a DNS to
allow access to pages served by the on device web server.
xPico® Wi-Fi® SMT Embedded Device Server Datasheet 33
Simultaneous Client and AP interfaces
The xPico Wi-Fi SMT device server has the ability to operate as Wi-Fi Client and provide a Soft
Access Point mode both at the same time. This allows the device to communicate to a network
access point, while simultaneously allowing up to four other clients to connect to it.
Service personnel do not need to determine the credentials of the network in which their product
is deployed in order to wireless gain access to the service interface on the product. Device
communication is maintained across both the AP and client interface without interruption.
WLAN Connection Management
Managing connectivity to wireless networks, retrying on lost connections, ensuring IP level
connectivity is maintained, working across re-configurations are all tasks that the WLAN
Connection Manager handles out of the box.
Combined with other features such as WLAN QuickConnect and WLAN Profiles, a robust and full
featured WLAN connection manager reduces connection downtime, enables quicker deployment
and eliminates the complicated state management that has to be implemented on connected
microcontrollers/devices to support such functionality.
WLAN QuickConnect
WLAN QuickConnect allows users to add setup/provision the wireless network configuration for
the WLAN client interface quickly by presenting an intuitive workflow and user interface that is
familiar to Smartphone users. It also simplifies the process of connecting to legacy wireless
networks that use WEP security via the EasyWEP capabilities built into QuickConnect and the
WLAN Connection Manager.
WLAN Profiles
In many scenarios, it is essential to store and connect automatically to one of multiple wireless
networks available. WLAN Profiles makes it easy to configure and store the settings associated
with these multiple networks.
Together with WLAN QuickConnect and the bulk configuration via XML, it makes the provisioning
process very straightforward.
Lantronix Serial to Wi-Fi Tunneling Application
Lantronix offers multiple modes for connected device data acquisition and control. Depending on
the nature of the application running on the connected microcontroller, these modes offer a
flexible and robust out-of-the-box solution that has been deployed across millions of units.
The xPico Wi-Fi SMT device server also support the ability to enable AES encryption of the users
TCP data for both Accept and Connect Tunnel Modes.
xPico® Wi-Fi® SMT Embedded Device Server Datasheet 34
Transparent Tunneling Mode
Legacy applications running on microcontrollers that cannot be modified or where the
requirements for data communication are simple, Transparent Tunnel mode provides a rich set of
configuration options and knobs to manage the connection management, data framing and
transfer process to suit many application protocol requirements.
The various features of transparent tunnel mode are:
♦
Accept Mode (Server mode for incoming connections)
♦
Connect Mode (Client mode for outbound connections)
♦
Triggered Connect Modes
♦
Hostlist Mode* (Multiple virtual serial session connectivitiy)
♦
Disconnect Mode (Session teardown options)
♦
Data Framing/Packetizing Options
♦
Session Establishment and Teardown trigger actions
♦
Choice of TCP, UDP*, TCP-AES, UDP-AES* encapsulation protocol
Modem Emulation Mode
Modem Emulation Mode supports the more traditional AT-command driven interface for
microcontrollers that can support interactive connection control and would like to switch between
control interface and data interface on demand.
It increases the overall state management complexity on the connected microcontroller compared
to Transparent Tunnel mode, but can be helpful where knowledge and usage of AT commands
(even though more complicated) is absolutely necessary
AES Security
The xPico Wi-Fi embedded device server supports the use of 256-bit AES encryption in order to
provide security protection of the User Data. Tunneling Security for TCP AES is enabled for both
Accept and Connect Tunnel configurations.
Application Aware Power Management Framework
The xPico Wi-Fi SMT device server is intended to be used in products that require or are
sensitive to the amount of power they consume, for example battery powered applications.
Consequently the power management framework for the xPico Wi-Fi embedded device server is
intended to provide a framework that users can manage their device power consumption
dependent upon their needs and requirements.
The framework offers application aware power modes that allow the user to choose the method
that meets their needs for a compromise between power consumption and the time to respond,
wake up and reacquire connectivity. It is generally accepted that the lowest power consuming
mode results in a longer response time from the power saving state to being fully active and
connected. The power management framework includes the ability to be managed by using a
dedicated Wake-Up System Pin.
xPico® Wi-Fi® SMT Embedded Device Server Datasheet 35
The Power Management Framework consists of three modes of operation.
1. Power Up Mode
2. Sleep Mode
3. Standby Mode
Power Up Mode
This is the only mode available if the Access Point is enabled or if none of the other Power
Saving modes are enabled for the WLAN interface. Even in the Fully Active mode, the xPico Wi-
Fi embedded device server provides some form of power savings capability. The xPico Wi-Fi
module supports “ps-poll” capability where a STA makes an initial association with an access
point, it negotiates and informs of its ability of going into a low power mode and what that low
power duration is. The Access Point must be capable of supporting the standard capabilities of
Traffic Indication Map (TIM) and Power Save Poll (ps-poll). The xPico Wi-Fi module automatically
manages this capability in the Fully Active Mode.
Sleep Mode
Sleep mode causes the xPico Wi-Fi device to power down the Wi-Fi radio and system clocks
while preserving the system state. This mode offers a compromise of power versus wake
response time for those applications that need reduced power consumption with a speedy wake
up and connection reacquisition response time.
Standby Mode
Standby mode of operation provides the lowest power consumption. In this mode the xPico Wi-Fi
has the only the RTC operating and the system runtime state is not preserved. This mode has the
longest wake up response time, since the system state has to be reinitialized and connections
reacquired.
Flexible Configuration Management Framework
The xPico Wi-Fi SMT device server provides a unified framework in how the device can be
controlled, configured and managed. For full details refer to the xPico Wi-Fi Embedded Device
Server User Guide.
• XML Import and Export
• Save/Restore configuration on Flash
• Reset to Defaults – Command and Hardware Pin
• OEM Configuration Management
• TLOG Display and Syslog Redirection
Web Page Customization
The xPico Wi-Fi embedded device server includes an embedded Web Server. This Web Server
provides the user a browser based configuration tool. The unit’s configuration is stored in
nonvolatile memory and is retained without power.
The Web Server has the ability to support the use of a custom landing page, which can take precedence
over the default home page. The pages can be modified to suit a customer’s need in regard changing
Logos, Background and Color Scheme, visible menus and options. Custom pages are supported with
data being capable of being sent or received to a connected host device.
xPico® Wi-Fi® SMT Embedded Device Server Datasheet 36
SNTP Client
The xPico Wi-Fi SMT device server provides support for Simple Network Timing Protocol. This
easy to configure integrated Client allows the user to be always be synchronized to Internet time.
Time can be synchronized either by using XML on the serial port or by using WebAPI.
Lantronix Application Toolbox for IoT solutions
Lantronix Application Toolbox for IoT solutions (LATIS) is an architecture that uses application
tools to support a easy to use “Customization by configuration” paradigm. An on device
Application Server facilitates the simple interfacing of network interfaces/Web server to Host
processor/Client with a common database/cache.
LATIS enables the user to create application specific customization of the end user product
without the need to use an SDK or write software.
Custom user Data from a Web Page can be stored and used via the on device FLASH File
system. Changes to data can initiate an interrupt that notifies a connected device to fetch the
updated data.
Serial Multiplexer
As an interface serial ports tend to be used as a dedicated data channel between two points. With
data generally being asynchronous with a simple “character” format that indicates the start and
stop and sometimes error checking. With the xPico Wi-Fi embedded device server there is a
need to establish multiple data channels in order to support multiple applications simultaneously.
This requires the need to create a protocol that supports the differentiation of data.
The xPico Wi-Fi embedded device server provides a “Mux” Line Protocol for the serial Line to
manage and transfer data on multiple connections without requiring custom software on the
device. A host processor that is connected to the device via the serial Line sees a simple
command/response interface. There are no intentional delays required in the normal handshake.
Over-The-Air Updates
xPico Wi-Fi SMT device server provides a robust and secure method for the updating of device
firmware over the internet. This update process uses the existing WLAN configuration and
preserves the user configuration and profiles.
Using the embedded web interface makes the update process simple and is user friendly. For a
more scripted and automated method the same updates can be done via the WebAPI.
Lantronix Query Port
The xPico Wi-Fi embedded device server supports the Lantronix query Port discovery service.
Query Port is a Lantronix proprietary protocol which implements a simple protocol on port 0x7FFE
(30718). This service can be used by the Lantronix network tools such as Device Installer or
ComPort Redirector.
