Function Upgrade: Security,Double Serial,Multifunction

Internal Structure of ti wifi module

The above is function structure chart of C322 firmware V2.0.Blue part is for original function, orange for new features of V2.0.
New features of firmware V2.0 includes double serial,three links, PC1 Encrypt, SSL encryption submission, http and Websocket communication mode.

Double Serial,Three Links

Double Serial Three Links

C322 has double serials and three network links.
UART 0 supports two network links and one link supports TCP Server;UART 1 supports one network link.
Application Example:
1.Communication with two servers:two UARTs connect with two different servers and receive different commands for the servers
2.Data backup and remote debugging:serial data sent to the two servers by using two network links of UART 0
3.TCP Server and TCP Client can work at the same time

Security of Communication Data

Security of Communication Data of ti wifi module

Firmware V2.0 has two encryption communication methods:
PC1 Encrypt:wifi module receives data,encrypts the data with PC1 Encrypt and sends the data to server;
SSL Client:use SSL Client to submit data to server

Data Submitted to Web Server Directly

Data Submitted to Web Server Directly

Httpd client function of C322 firmware V2.0 supports direct data interaction with web server.If send serial data to module according to some format, data will be submitted to web server like apache,IIS and tomcat in the way of Http. General web programmer can process database storage by using PHP and ASP.

Built-in Webpage with Custom Extensions

Built-in Webpage

C322 built-in webpage supports user-defined functions.
C322 supports function of Ethernet to serial, which adopts HTML5 Websocket technology. Combined with custom webapge function, User can design built-in webpage to realize webpage control and data acquisition according to project requirement.

Test Report:Reliable Transmission,Lowest Power

After go into sleep mode,C322 will go through three stages:
average current of 3.5ma in sleep mode;¡ after data sent to wifi module,wifi module wakes up quickly and begins to send data;â‘¢ if no data sent to wifi module within 10s, wifi module will enter sleep mode again.

Data sending test:

Test Report of ti wifi module
network termination sends 34000 bytes at a time and serial receives 34000 bytes;
network termination data wakes up wifi module and transmits to serial without data loss.
