market and application
Using BT578 purpose is to replace the original serial port cable, but how to replace the user before buying the product should have a clear plan. Here are several kinds of typical BT578 application way.
BT578 from the machine, through the DB9 serial port to the serial port equipment, with bluetooth laptops, USB bluetooth adapter, bluetooth tablet or cell phone and other bluetooth main equipment matching connection to use. This is the most common BT578 one way to use. BT578 from the machine can only wait for the bluetooth device to find, after finding from the machine when the main equipment, from the main equipment matching requests, and input the correct from the machine on the main equipment matching password validation (pairing BT578 the factory default password is 0000), the pairing is completed, the bluetooth master device for a bluetooth virtual serial port number assigned BT578, run on the main equipment of serial port communication applications only need to use the virtual serial port, setting, can with BT578, serial communication and connection with BT578 serial port to a serial port communication equipment.
BT578 from machine and BT578 host used in pairs. First through the AT command, set a BT578 to host, then the host and from the machine from the original serial cable is connected respectively two serial ports, the host will automatically be search from machine and electricity with complete matching connection from the machine. After the connection is successful, the host and the blue indicator light on the flash, flash into double green light is long.
BT578 host connection bluetooth from the equipment. Host after electric will continue to search for bluetooth devices around and try to match, if the surrounding a bluetooth device response BT578 matching counterpart of the request and use the same password, can be matched.
