(first the summary: need bluetooth ic formp3 or for making cellphone calls ( using sara u201))
Hi,
so I'm working on a project that involves streaming audio (music, ...) throught bluetooth, basically a bluetooth mp3.
The mcu I'm using is an stm32, some bluetooth ic/modules are cyw___,csr___,bm__,cc256__.
The rn 52 and the cc2564 look like could work but the first one looks expensive and for the secons looks like a need a bsd sofftware (can't comercialize it, for the moment I dont care);
The problem is that I don't find any bluetooth ic for this I think I need a bluetooth 5 ic but everytime i find someting it follows this path.
Phone or pc (with their own bluetooth ------>speaker(with the bluetooth ic implemented)
The simplified diagram of the product would be (no audio codecs tc)
stm32 (with the bluetooth ic implemented)----->speaker(with his own bluetooth)
I'm not really good at explaining myself sorry
