BM64 bluetooth module supports the following profiles : A2DP 1.3, AVRCP 1.6, HFP 1.6, HSP 1.2 and SPP 1.2
Using the A2DP I can stream audio output to a speaker as it is for a sink, thus a speaker.
I want to send some information from the uC to the bluetooth module and thus to whatever device is paired with the module probably using SPP.
However, is that possible while still transmitting audio from the paired device to the module?
i get that they are different profiles, but my question if it is possible to send my data over A2DP instead of SPP. even if it was not audio, while handling the software side properly.
