I am taking part in a project as part of a challenge and I'm in charge of the embedded systems part, this is my first time working on a project of this scale. I am looking for a way to wirelessly send in real time audio recorded from arduino microphone and the information retrieved from the temperature and the heart rate sensor to a server for it to be treated by a data scientist (he says he needs in in .wav format). Any hardware suggestions and useful link and advice on the steps to take for this kind of project? do any of you have an idea on how to transmit that kind of information I am only used to serial communication (the back-end developer tells me I have to send JSON queries to communicate with the database). Thank you very much!
