The device is a smart sensor with the ability to acquire and store: Breathing, motion, Ambient light and Temperature. It has the ability to interface to a smart device via Bluetooth in order to receive commands to start and stop acquisition and also to forward the stored data. It is also able to send notifications to the smart device when certain environmental and internal events occur.

• Developed the secondary bootloader code with upgrade options
• Developed the JSON RPC handler to process the received request
• Developed a sample iPhone Application to test the application

eLoopback CFP module is designed in CFP module form factor and it can be accommodated in standard CFP host cage. It is designed for looping back the incoming 1 Gbps lanes to provide test feature for other CFP modules. It uses a Microcontroller for implementing MDIO slave interface (Clause 45, defined for CFP Specification) and dummy loads to dissipate certain amount of power in according to CFP specification.

• Developing and customizing low-level driver for MDIO to communicate with the host
• Developing and customizing low-level driver for I2C to read the data from EEPROM
• Functional testing of MDIO Driver to communicate between the host and the module
• Board Bring up of complete system
