This email sent to site_archiver@lists.apple.com Hi All, We are thinking of make an accessory. It is a medical device that must run for 8 hours generating sounds defined by some parameters. In order to change them the patient males a VOIP with the doctor and then the doctor updates them in real time. The patient must ack that the new parameters are ok. Then, the connection finishes and the patient turns off the BT connection. We have discarded audio streaming due to have better battery perfomance. Could i implement SPP and HFP at the same time? If not, is it possible to implement a low level BT programming on the devices mentioned? Thanks!
