RomWebClient?

A Robust HTTP Client Enabling IoT Devices to Communicate Over the Internet?

RomWebClient? toolkit enables your embedded device to fully support HTTP 1.1 for sending and receiving HTTP objects in any format with any Web server.

RomWebClient??Overview

Allegro’s RomWebClient? toolkit allows your engineering team to leverage proven Web technology when creating custom IoT devices. The RomWebClient? toolkit enables embedded engineering teams to build products that send and receive objects to and from any Web server using HTTP with full support for IPv4 and IPv6 operation. For secure communications, RomWebClient? is tightly integrated with Allegro’s RomSTL? TLS toolkit to make full use of TLS v1.3 with FIPS 140-2 and Suite B cryptography. By utilizing RomWebClient? technology your IoT devices can communicate with Cloud-based resources, download configuration files, retrieve software updates, and much more.

 

RomWebClient

RomWebClient?

The RomWebClient? toolkit enables your embedded device to fully support HTTP 1.1 for sending and receiving HTTP objects in any format with any local or cloud based Web server. MIME definitions for all standard MIME object types are provided in addition to allowing support for non-standard MIME types. HTTP objects can be sent or received from memory or an optional file system. Both HTTP direct requests and proxy server requests are supported. For authentication, HTTP Basic and Digest methods are provided and are compliant with RFC 2617. The RomWebClient? toolkit also has built-in support for advanced caching, pipelined requests, proxy authentication, large object data streaming, and HTTP cookies. Delivered as ANSI-C source code the toolkit is built upon a highly portable and field-proven abstraction layer enabling it to work with any OS or TCP/IP stack.

RomXML? and RomXML Plus?

The RomWebClient? toolkit is pre-integrated with Allegro’s RomXML? and RomXML Plus? toolkits allowing manufacturers to easily built advanced device management architectures that require XML, REST, JSON or SOAP-based communications with Cloud-based resources. The RomWebClient? toolkit includes support for integrated retrieval and transmission of XML objects when used in conjunction with the RomXML? and RomXML Plus? toolkits. This allows your design team to create devices that initiate XML-based request/response protocols such as JSON, REST and SOAP making them easier to integrate with enterprise information systems.

RomSTL? – Embedded TLS

Security is always a concern when dealing with devices connected to the internet. RomSTL? addresses the need for advanced security with integrated TLS 1.3 support. With support for a variety of cipher suites (RSA, DHE, RC4, DES, 3DES, AES, SHA, CBC, and MD5) and full integration with Allegro’s FIPS 140-2 validated cryptography and Suite B, your development team can provide compatibility with all standard secure browsers. RomSTL? also offers a built-in certificate authority, certificate import support and Basic and Digest Authentication under TLS. Compliant with IETF standards (RFC 8446 and RFC 5246), RomSTL? provides RomWebClient? with the advanced security functionality to meet your development team needs.

Highly Portable

The Allegro EdgeAgent Suite is highly portable across RTOS and processor families. Delivered in ANSI-C source code all products utilize a field-proven abstraction layer to enable portability with any RTOS, TCP/IP stack, and file system environment. Interface files for leading RTOS environments are provided.
