OVC3860 AT Command Application Notes
1 Overview
User can use the UART serial port to communicate with OVC3860 chip, and implement bluetooth h
eadset/handfree and stereo headset functions through sending AT command. The UART serial port
use-s tow signal wires: Tx and Rx, soppurting 1200, 2400, 4800, 9600, 14400, 19200, 38400, 5760
0, 115200, 230400, 460800 and 921600bps baudrate. The default baudrate is 115200bps.
2 The States of Bluetooth Application
These status number is combined with the Indication Strings like “MG”,”MU”,”ML”.
HFP Status Value Description:(MG)
1. Ready (to be connected)
2. Connecting
3. Connected
4. Outgoing Call
5. Incoming Call
6. Ongoing Call
A2DP Status Value Description:(MU)
1. Ready (to be connected)
2. Initializing
3. Signalling Active
4. Connected
5. Streaming
AVRCP Status Value Description:(ML)
1. Ready (to be connected)
2. Connecting
3. Connected
3 AT Command Operations
