I would like to create a BT audio streaming device, i.e, bluetooth loudspeaker. This device has a few LEDs and a display. Any Android/iPhone device can connect to it and transmit audio. I also want to add some private GATT characteristics in order to allow those LEDs and display to be changed. I would like to know which are the BT ICs available for that, i.e, BlueNRG, STMWB and so (development kit available?). Thanks!
