How to change the Bluetooth device icon for BT1036 module?

Sang

Hello，I just bought a BT1036 module. When I connect it to my phone or PC, it shows a default Bluetooth icon. Is it possible to change this to something else, like a headset or a printer? How can I do that?

Hi Sang,

Yes, absolutely! You can change the icon that appears on your host devices (phone/PC) by modifying the Class of Device (CoD) parameter of your BT1036 module.

The CoD tells the host device what kind of device it is, and the OS then assigns an appropriate icon.
How to change it:
Use the AT+COD command followed by the 6-digit hexadecimal code for your desired device class.
Examples:

// Set Device Class (COD)
AT+COD=001F00    // Generic Bluetooth device
AT+COD=240404    // Headset device
AT+COD=040680    // Printer device

After sending the command, restart the module or toggle its power. The new icon should appear on your phone's or PC's Bluetooth list upon the next connection.

Finding more CoD codes:
The CoD can be defined for many device types. For a more comprehensive list of codes, you can visit this third-party website:

We hope this helps! Let us know if you have any other questions.

FAE_Gavin It works! I sent the AT+COD=240404 command as you suggested, and the icon on my phone immediately changed to the headset style. Perfect!
