This case study entertainment.showcases Mistrals capability in providing a ZigBee technologybased solution for a Universal Remote Controller. The product is now The Requirementgoing into large volume production by the customer. The customer came up with the concept of providing an easy access to TV programs, and controlling the various IR devices using an iPhone, iPad (or any other device from Apple Inc.) interfaced with wireless access points/routers. Both these devices are very common in any US household. The concept involved development of intermediate devices between the iPhone and the end IR-device. The intermediate devices, called Node and the Hub, are based on ZigBee technology. The customer came up with two ZigBee devices that would address this requirement and approached Mistral to provide the ZigBee based firmware solution for these two intermediate devices. Solution Provided Mistral provided the customer with a ZigBee firmware solution, using the CC2530 ZigBee SoC from TI with Stellaris Microcontroller. The Hub plugs into a Wireless router using Ethernet and communicates to the Node using the ZigBee protocol. The Node emits IR to the endpoint IR-devices. iPhone communicates to the Hub using the UDP protocol. The Hub operates on AC power and the Node is battery operated. The Challenges !
