Li Market and Application

The purpose of using BT578 is to replace the serial cable, but how to replace the user before buying the product should have a clear plan. Here are some typical applications of BT578.
• BT578 from the machine through the DB9 serial port connected to the serial device, and Bluetooth, notebook computers, USB Bluetooth adapters, Bluetooth, tablet PCs or mobile phones and other Bluetooth host device pairing, connection use. This is one of the most common uses of BT578. BT578 wait for the Bluetooth master from the machine only to find, when the main equipment found in the machine after a pairing request from the master device, and the main equipment to enter the correct pword verification from machine matching (BT578 factory default pairing pword is 0000), the pairing is completed, the main equipment will be igned a Bluetooth Bluetooth virtual serial port No. BT578, running on a host device serial communication applications only need to set the virtual serial port, can serial communication with the BT578, and the serial communication with BT578 connected to the serial device.
The BT578 slave and BT578 host are paired. First through the AT command, a BT578 is set to host, then the host and received two serial serial cable connection from the machine, the host power will automatically search from the machine and machine from paired connection. After the connection is successful, the blue light on the host and slave is changed from flash to double flash, and the green light is bright.
The BT578 host connects Bluetooth to use from the device. After the host is powered on, it constantly searches for the surrounding Bluetooth device and tries to pair it up. If the peripheral Bluetooth device responds to the pairing request of BT578 and uses the same pairing pword, it can be paired successfully.
