Do you have the UART setup for the correct baud rate etc ?

Four signals are provide for UART function. TXD and RXD transmit data between
AUBTM-20 and the host. NRTS and NCTS provides the RS232 hardware flow control
mechanism. All UART pins are CMOS logic with signal levels of 0V to VDD.

Do you understand hardware flow control ?

Hi,

I bought an aubtm23 chip and I want to use it to act as a bluetooth transmitter, i.e. to receive sound from microphone port and send it via bluetooth to a bluetooth speaker or handsfree. It is act as a bluetooth handsfree by default. May you please guide me to make it?
