If you don’t have the time, patience or computer skills to update the driver manually, you can do it automatically with Driver Easy.ĭriver Easy will automatically recognize your system and find the correct drivers for it.
If uninstalling the bluetooth device driver doesn’t work for you, you can try to update the driver. (If you see more than one bluetooth device under this category, uninstall them one by one.)Ĥ) Restart your computer and check to see if the problem is resolved. You can follow these steps to uninstall and reinstall the driver:Ģ) Type devmgmt.msc in the run box and click OK.ģ) Expand category “Bluetooth Radios”, right click on one bluetooth device and select Uninstall. You can uninstall the bluetooth device driver and reinstall it to see if this resolves the problem. The problem can be caused by faulty bluetooth device driver.

Right-click on it and select Properties.Ĥ) Change the “Startup type” to Automatic and click the Start button to start the service.Ħ) Restart your PC for the changes to take effect, and check to see if the problem is resolved.

Follow steps below to check for service status.ġ) On your keyboard, press Win+R (the Windows logo key and the R key) at the same time to invoke the Run box.Ģ) Type services.msc in the run box and click the OK button.ģ) From the Name list, locate Bluetooth Support Service.
The error would occur if the bluetooth support service is not started. Solution 3: Update the Bluetooth Device Drivers Solution 2: Uninstall then Reinstall the Bluetooth Device Drivers Solution 1: Check for Bluetooth Support Service You may not have to try them all just work your way down until you find the one that works for you. We’ve put together four solutions below to fix the error. You can easily fix the error with one of the solutions below. Service Discovery Protocol (SDP)− SDP takes care of service-related queries like device information so as to establish a connection between contending Bluetooth devices.Īpplications Layer − This includes the application profiles that allow the user to interact with the Bluetooth applications.If you run into error Unable to start the Bluetooth stack service, don’t worry. The commonly adopted protocols used in Bluetooth are Point-to-Point Protocol (PPP), Internet Protocol (IP), User Datagram Protocol (UDP), Transmission Control Protocol (TCP), and Wireless Application Protocol (WAP).
WHAT IS BLUETOOTH STACK SERIAL
It provides a serial interface with WAP.Īdopted Protocols − These are the protocols that are adopted from standard models. RFComm − It is short for Radio Frontend Component. Middleware Layer − This includes Radio Frequency Communications (RFComm) protocol, adopted protocols, SDP, and AT commands. L2CAP provides support for both connection-oriented as well as connectionless services. Logical Link Control and Adaptation Protocol (L2CAP) − L2CAP provides adaption between upper layer frame and baseband layer frame format. The other main functions of LMP are device authentication, message encryption, and negotiation of packet sizes. Link Manager Protocol (LMP) − LMP establishes logical links between Bluetooth devices and maintains the links for enabling communications. It defines the addressing scheme, packet frame format, timing, and power control algorithms.ĭata Link Layer − This includes Baseband, Link Manager Protocol (LMP), and Logical Link Control and Adaptation Protocol (L2CAP). It defines air interface, frequency bands, frequency hopping specifications, and modulation techniques.īaseband − This protocol takes the services of radio protocol. Radio − This is a physical layer equivalent protocol that lays down the physical structure and specifications for transmission of radio waves. Physical Layer − This includes Bluetooth radio and Baseband (also in the data link layer. Protocols in the Bluetooth Protocol Architecture The protocols in the Bluetooth standard can be loosely grouped into the physical layer, data link layer, middleware layer, and application layer as shown in the following diagram − The Bluetooth architecture has its own independent model with a stack of protocols, instead of following the standard OSI model or TCP/IP model. Bluetooth network technology connects mobile devices wirelessly over a short-range to form a personal area network (PAN).
