TruPort Serial
TruPort Serial, a robust serial to Wi-Fi and serial to Ethernet application that supports the
transparent transport of hundreds of serial protocols over the network. TruPort Serial is very
suitable for use in network co-processor mode based applications requiring 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 Socket
Connect your device microcontroller to multiple services and communicate directly with mobile
devices and cloud services at the same time via TruPort Socket. The simple API for TruPort
Socket is available via the UART, SPI Slave, 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 host microcontroller.
Access TCP, UDP, TLS, HTTP, SMTP channels and communicate with external services
through these channels without implementing these protocol stacks within your microcontroller.
Ethernet to Wi-Fi Bridge
For devices with microcontrollers that include a network stack and also have Ethernet
connectivity available, the gateway module software provides wireless connectivity to these
devices via the Ethernet to Wi-Fi Bridge mode. Ethernet connected host devices can be
accessed remotely via the Wi-Fi Client interface or via the Wi-Fi Soft AP interface. 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.
Concurrent Soft AP and Client Mode
In addition to supporting the standard Soft AP only mode, Client only mode, xPico 200 series
also supports concurrent Soft AP and Client mode.
In this mode, clients can create a direct connection to the Soft AP interface of the gateway,
while the Client interface is connected to the Enterprise Wi-Fi network.
This enables OEM service and support teams to setup a direct connection to their machines to
diagnose, troubleshoot and service them via mobile devices without requiring access to the
customer's Wi-Fi network.
