Bluetooth Device (RFCOMM Protocol TDI) Driver for Windows 10 and 11 – Download & Fix Guide
Jun. 13, 2025 / Updated by Violet to Windows Driver Solutions
The Bluetooth Device (RFCOMM Protocol TDI) driver is a critical component that allows Bluetooth-enabled devices to communicate over the RFCOMM protocol, an emulation of serial ports used for communication between Bluetooth devices. Without this driver, Windows 10 and 11 systems may fail to recognize or communicate properly with devices like wireless headsets, serial adapters, or industrial Bluetooth modules. This comprehensive guide addresses everything you need to know about installing, downloading, updating, and fixing the RFCOMM Protocol TDI driver on both Windows 10 and Windows 11.
What Is the Bluetooth Device (RFCOMM Protocol TDI)?
The RFCOMM (Radio Frequency Communication) Protocol TDI (Transport Driver Interface) is a protocol that mimics serial port communication over Bluetooth. It enables legacy serial-port based applications to interface with modern Bluetooth devices. The Bluetooth Device (RFCOMM Protocol TDI) driver acts as a bridge between your Bluetooth stack and applications that rely on COM port emulation.
Common Issues Related to RFCOMM Protocol TDI Driver
Users commonly encounter the following issues:
“Bluetooth Device (RFCOMM Protocol TDI) driver is missing” in Device Manager
“Bluetooth not working” after a Windows update
Yellow exclamation mark next to the RFCOMM driver in Device Manager
Inability to pair serial Bluetooth devices
Code 28 errors indicating missing drivers
How to Fix Bluetooth Device (RFCOMM Protocol TDI) Driver Issues on Windows 10 and 11
1. Automatically Update RFCOMM Protocol TDI Driver with Driver Talent
When facing Bluetooth issues, the fastest and most reliable solution is to use an automated driver updater. Driver Talent offers a smart, user-friendly way to detect missing or outdated drivers and update them with a single click.
Steps:
Download and install Driver Talent from the official website.
Launch the application and click "Scan" to detect driver issues.
Find Bluetooth Device (RFCOMM Protocol TDI) in the list.
Click "Repair" or "Update" to install the correct driver.
Restart your computer to apply changes.
Driver Talent also backs up your existing drivers, so you can roll back if needed. This is ideal for users who lack the technical expertise to manually handle driver installations.
2. Manually Update the RFCOMM Protocol TDI Driver via Device Manager
Device Manager connects to Microsoft’s driver library and attempts to find the best match for your hardware. While not always the most up-to-date, it can resolve compatibility problems with minimal user intervention.
Steps:
Press Windows + X and choose Device Manager.
Expand the Bluetooth section.
Right-click on Bluetooth Device (RFCOMM Protocol TDI) and select Update driver.
Choose “Search automatically for updated driver software.”
Let Windows find and install the best available driver.
If this method doesn’t yield results, proceed with a manual download from the manufacturer’s website.
3. Download Bluetooth Device (RFCOMM Protocol TDI) Driver from Manufacturer Website
Manufacturers like Intel, Broadcom, Realtek, and PC brands like Dell, HP, Lenovo, and ASUS often publish Bluetooth drivers optimized for their systems. These are sometimes newer or more stable than what Windows Update provides.
Steps for Windows 10 and 11 Downloads:
Go to your PC or laptop manufacturer’s support page.
Enter your device model number.
Filter the drivers list by Operating System (Windows 10 or 11).
Look for drivers labeled Bluetooth, RFCOMM, or Serial Port over Bluetooth.
Download and install the package.
Reboot your computer to apply changes.
This method is particularly effective when your PC was pre-installed with a proprietary Bluetooth stack.
4. Reinstall RFCOMM Protocol TDI Driver
If you're dealing with driver corruption or faulty installation, simply reinstalling the driver can resolve the issue. This is a safe and straightforward fix that often works when other methods fail.
Steps:
Open Device Manager.
Find and right-click on Bluetooth Device (RFCOMM Protocol TDI).
Select Uninstall device.
Confirm the action and reboot your PC.
Allow Windows to reinstall the driver automatically.
If Windows doesn’t reinstall it, use Driver Talent to restore or update it quickly.
5. Enable Hidden Devices and Add Legacy Hardware in Device Manager
Sometimes, the RFCOMM driver is installed but hidden or disabled, especially after major system updates. Enabling hidden devices and manually adding legacy hardware can help bring it back.
Steps:
Open Device Manager.
Click View > Show hidden devices.
Check under Bluetooth or Ports (COM & LPT) for the RFCOMM entry.
If not found, go to Action > Add legacy hardware.
Follow the wizard to manually install Bluetooth Device (RFCOMM Protocol TDI).
This method is especially useful for users managing older hardware or external Bluetooth adapters.
6. Install Microsoft Bluetooth Enumerator
The Microsoft Bluetooth Enumerator is often a prerequisite for the RFCOMM Protocol TDI driver to work correctly. If your Bluetooth adapter doesn’t support enumeration natively, adding this can solve your connection issues.
Steps:
Open Device Manager.
Click Action > Add legacy hardware.
Select Install the hardware that I manually select from a list (Advanced).
Choose Bluetooth > Microsoft Bluetooth Enumerator.
Install and reboot your PC.
Once installed, retry pairing your Bluetooth device or check the COM port assignments.
How to Confirm the Driver Is Installed Correctly
After completing any method:
Go to Device Manager.
Confirm Bluetooth Device (RFCOMM Protocol TDI) appears under Bluetooth.
Ensure there are no yellow warnings or error codes.
Check Ports (COM & LPT) to verify a COM port is assigned.
Test by pairing a Bluetooth serial device (like an adapter or modem).
Conclusion
The Bluetooth Device (RFCOMM Protocol TDI) driver is crucial for seamless communication between your system and many Bluetooth-enabled devices. Whether you’re dealing with connection drops, pairing failures, or unrecognized devices, fixing this driver ensures proper operation and system stability on Windows 10 and Windows 11.
While manual methods exist, they can be time-consuming and complex. That’s why we strongly recommend using Driver Talent—a professional-grade driver manager that handles all your driver needs with a single click.
