I am working on a project in which we need to develop an interface device that connects various medical sensor devices to Series 40 and Series 60 Nokia phones (and similar), and other "feature phones" (i.e. non-"smart" phones). The project aim is to keep things low-cost, as the target audience is emerging countries, and specifically primary health clinics in rural villages. We are considering the RPi as an option for the interface device, as it appears to meet most if not all requirements. The idea is: the interface device will receive data (most likely as packets of strings) from the medical sensors, perform additional computations on these data packets, and then relay them to the phone. The interface device requires the ability to connect to as many different types of "feature" phones as possible - including smart phones in the near future. The focus initially will be "feature phones". The sensors will connect to the interface device via USB, and present itself to it as a "CDC device" (although this is not yet set in stone). Any pointers and tips would be much appreciated!
Please help
I didn't find the right solution from the internet.
