We are building an IOT product (hardware) which would handshake with an android / windows runtime (application) via BLE, WiFi, USB (one of them at a time). After connecting with one or more devices, the runtime would send requests to these nodes retrieving data from a database. It would also display data based on the response received from the nodes. The response from nodes would also be uploaded to a cloud for future reference. More details of the project would be discussed separately with the right freelancers.
