TiWi-C-W Development with Serial-to-WiFi API

This online guide is intended to provide helpful documentation, videos, and tutorials for developers utilizing the TiWi-C-W Development Kit featuring Serial-to-WiFi (#450-0164)

What is Serial-to-WiFi?

LSR is excited to introduce Serial-to-WiFi, a serial communications API that jump-starts your WiFi integration when utilizing our latest generation certified embedded WiFi module, the TiWi-C-W. Serial-to-WiFi accelerates your IoT development by providing a simple, easy-to-learn approach to enable socket-based WiFi communications through serial commands from your existing design's microcontroller.

Serial-to-WiFi is a powerful API created to free up more of your development time by dramatically simplifying the work of adding a TCP or UDP socket connection to your embedded product. More than just a simple network processor, Serial-to-WiFi provides a connection management layer within the TiWi-C-W module that intelligently manages the WiFi and socket interfaces. This means that your design's host microcontroller doesn't need to run a TCP/IP stack or any other network management software; it can simply send a 'Socket Open' command and begin communicating!

With TiWi-C-W, you have a certified module that simplifies your path to creating your IoT product. Pairing it with the innovative Serial-to-WiFi API and tools means it's never been easier, or faster, to develop a robust WiFi application in YOUR product.

PC Host for Serial-to-WiFi

Serial-to-WiFi provides a UART-based serial communication schema based on JSON-RPC. This human-readable, structured, request/response approach takes virtually all of the complexity that comes with a traditional AT command set approach. This minimizes the learning curve even for developers who may be new to Wi-Fi.

To quickly learn and explore this schema, the PC Host for Serial-to-WiFi desktop application empowers you to exercise every command in the API, with your PC laptop acting as the host controlling your TiWi-C-W Development board. So from this application you can directly instruct the Wi-Fi module to perform a particular action such as scanning for Wi-Fi networks, joining a Wi-Fi network, opening a socket connection, etc. This gives you a real-time view of the serial data sent over UART between your product's micro and the TiWi-C-W module, without investing a single minute of time up front developing firmware for your MCU.
