We're going to synthesize some audio and want to transmit over Bluetooth from our embedded device to a Bluetooth headset. Also need to do SPP output. We can provide audio output over I2S or just serial.
BC127 module can do this but is obsolete. Many modules can only act as slave for audio, and I'm defeated by vendor websites with lots of pretty photos and singing and dancing, but no clarity on what their products can do...
Anybody able to recommend a module that can do this (with external antenna) ???
Thanks!
