The GainSpan VGA Video Application Development Kit (ADK) is a complete reference design that demonstrates a VGA resolution (640*480) video streaming application based on the GainSpan GS2011MIZ Wi-Fi module and associated embedded and mobile software suite. The Video ADK finds applications in Wi-Fi doorbells, car backup cameras, baby monitors and IP cameras.
The Video ADK includes the video application board, hardware design package, and complete software suite including GainSpan embedded software and mobile reference applications for iOS/Android based smartphones. An evaluation version of the ADK, the Video Application Evaluation Kit (AEK) is also available that includes the application hardware and binary-only software.
The ADK hardware and software provide customers a starting point to build video streaming applications.
Operational Modes and Use Cases
The GainSpan module running the video application operates as a limited access point (Limited AP Mode) or as a client within an existing network infrastructure (Client/Station Mode).
Once the smartphone has established connection with the video ADK board operating in Limited AP mode, the mobile application discovers the video application profile being advertised by the embedded application and selects it to enable streaming of video from the camera to the smartphone. The mobile application features a custom player that plays the video stream from the camera.
In the Client mode, the Video application board connects to an AP as a client. The smartphone, also connected to the same AP, now discovers the Video embedded application profile, and upon selection, starts receiving the video feed from the camera.
Both the Limited AP mode and client/station modes provide mDNS/DNS-SD based discovery methods. The embedded application advertises availability, and clients automatically discover the video profile and connect to it. Discovery allows clients to locate and connect to Video applications without the need to know the URL.
Provisioning of the GainSpan node in Limited AP or Client/Station modes and Over-the-air firmware updates (OTAFU) of the GS2011M module firmware can be done using Provisioning and OTAFU web or mobile applications.
