No, it doesn't work. I think the problem is that I want to make it without a "true phone" connected to the handsfree. I want my application send a message to my device and the device must sound like a incoming call.
Other problem is that the Funker handsfree device has four buttons (ON-OFF, +, -, MODE), and the event OnData only raises when I push the ON-OFF button, with the message "AT+CKPD=200".
