ClarinoxWiFi, our complete WiFi stack solution

Embedded Market Forecasters report; 53.5% of wireless developments for the following 12 months intend to include IEEE802.11a/b/g/i or n standard. In the same report, a performance analysis of Wi-Fi® projects in the past 12 months revealed that 10.7% were cancelled and 39.1% were behind schedule. These figures are testimony to both the popularity of the technology and the extraordinary challenges present in WiFi developments. For over a decade, Clarinox has collaborated with national and international clients to develop breakthrough wireless embedded products. We have used our experience to implement IEEE802.11a/b/g/n, AP, STA, P2P and GO for a range of embedded platforms. You’ve experienced the hard way – let Clarinox make your next embedded WiFi project easier.




ClarinoxWiFi is a developer-friendly WLAN software protocol stack, designed exclusively for the development of embedded wireless LAN applications. The WLAN stack allows users to develop complex applications that support WiFi station mode, accesss point mode or peer to peer mode. The stack handles complex applications utilising both multiple profiles and multiple local Bluetooth® devices, allowing an application to interact with several local Bluetooth devices simultaneously.


The ClarinoxWiFi WLAN protocol stack is contained within the ClarinoxSoftFrame portable framework, allowing users to develop their applications using C/C++ on different hardware and operating system platforms with confidence of compatibility. Combined with the compactness of the protocol stack, this enables use with a number of architectures.

Simple API

The simplicity of the ClarinoxWiFi API greatly reduces application development times. The plain language style also facilitates faster test and debug cycles.

ClarinoxWiFi Features

  • Supports AP, STA and P2P modes
  • Supports multiple simultaneous roles
  • ClarinoxSoftFrame architecture isolates application from lower layers; can be used with any OS and TCP/IP stack
  • Supports a wide range of embedded platforms
  • Enables single and multi-threaded applications
  • Exposes blocking and non-blocking API calls
  • Built-in protocol analysis tool enables faster debugging
  • Extensive driver-level API for management and configuration of wireless links and networks
  • Suitable for applications in infotainment, data transfer, navigation, video streaming and health & medical devices


ClarinoxWiFi Stack

ClarinoxWiFi stack supports many common WiFi modes for embedded hardware such as Aceess Point (AP), Station (STA), Peer-to-Peer and WiFi Protected Setup (WPS). ClarinoxWiFi provides a set to API for initialization and de-initialization of the WLAN stack and another set of API's for performing WLAN management operations, such as scanning for access points, connecting etc. The data traffic is routed through a separate Network stack interface layer. ClarinoxWiFi supports many different TCP/IP stacks, i.e. LWIP, RTCS, NETX, Autosar.

For ensuring secure wireless connectivity the stack supports WPA/WPA2 Personal, WPA/WPA2 Enterprise encryption protocols in station mode operation. It supports encryption protocols WPA/WPA2 Personal for applications using access point mode.

ClarinoxWiFi supports WLAN modules manufactured by Texas Instruments, Marvell and Realtek, i.e WL18xx family, WL12XX family, Mv88w8xxx family and RTL87xx family WLAN modules. The WLAN stack supports both SPI (1 bit SDIO) and SDIO communication interfaces to the WLAN hardware modules, with interface clock speeds as low as 500 kHz for low speed low energy applications using Texas Instruments WL18xx chipsets.

The integrated ClariFi Debugger interface of the ClarinoxWiFi provides useful insights into the operation of the WLAN stack. This includes debug information spanning from low level WLAN module commands all the way upto TCPIP protocol message wireshark views.
