## **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._

## _**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.

## _**10: Software Features**_ 

## **Software Architecture Overview** 

The following represents the functional block diagram and architecture of the Lantronix xPico WiFi SMT family of embedded device servers. 

Lantronix Applications and Services Lantronix Enhanced Systern Services 

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_ 

_32_ 

## **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_ 

_33_ 

## **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.

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 WiFi 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.

## **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.
