Application examples for BT580 serial Bluetooth adapter

admin

Communicate with Android mobile phone and send remote AT command

1. please download a APP named "ATBlue" from this URL: http://www.irxon.com/download/ATBlue-EN.rar
After extracting the compressed file and installation on a Android mobile phone, tap "ATBlue" icon to run the APP.In Android 6.0 and higher version, a coarse location permission is needed in Bluetooth searching.
When you run "ATBlue" for the first time, please give the APP location permission, select "While Using" or "Allow".




2. In "ATBlue" APP, tap "SCAN" to search nearby Bluetooth devices, tap "BT580" in the found devices list to connect.




3. A Bluetooth link between Android mobile phone and BT580 adapter will be established (the blue LED turns steadily on).
Type remote testing AT command "AT+BT" at the bottom of screen, then tap "SEND", if the adapter returns a message "OK" in upper screen, it means the testing AT command was run successfully, you can proceed with more AT commands.




4. BT580 Serial Bluetooth adapter is usually connected to a serial device by serial port, and then communicates with a mobile phone via Bluetooth.
The default serial settings of the BT580 are 9600,N,8,1, if this settings is different from serial settings of the device, you can change BT580 serial settings by send AT command, make BT580 adapter and the device have same serial settings.
Let's take serial baud rate as an example, we need to change BT580's serial baud rate to 115200bps.
Send to the adapter the Inquiring Baud Rate command "AT+BAUDRATE=?".
The return message say the serial baud rate is "3".
Look up BT580's User Guides, the code "3" means the current serial baud rate of BT580 adapter is 9600bps.




5. According to User Guides, the code of 115200bps is "7".
Send Changing Baud Rate command "AT+BAUDRATE=7", the return message say the serial baud rate is set to 115200.



6. You must send command "AT+RESTART" to restart the adapter for new baud rate to take effect.  
Restarting the adapter will cause the Bluetooth connection "disconnected".



After restarting, the BT580's serial port will work at baud rate of 115200bps.

For more AT commands, please refer to BT580 User Guides: http://www.irxon.com/english/580/BT580_EN.pdf
