The Open Health Assistant document summarizes the work done to advance open source implementations of Continua Health Alliance protocols. It developed a fully functional implementation of Bluetooth profiles for communicating with biomedical devices according to Continua standards. It also implemented the Continua Optimized Data Exchange Protocol and device specialization protocols. The implementation provides an open API for applications to connect to eHealth services and access data from devices like glucose meters and activity trackers. Future work will focus on open interfaces between disease management services, remote devices, and electronic health records.
