Windows 10: bluetooth advertisements throttled

Discus and support bluetooth advertisements throttled in Windows 10 Drivers and Hardware to solve the problem; I have a Lenovo P52 with OS Build 19042.630 where I run a custom application that receives Bluetooth advertisements from a proprietary device....

  1. bluetooth advertisements throttled


    I have a Lenovo P52 with OS Build 19042.630 where I run a custom application that receives Bluetooth advertisements from a proprietary device. Something has changed in recent months such that the rate at which the application receives advertisements drops dramatically while I'm using the laptop. After exactly 10 minutes of inactivity, the application starts receiving advertisements at the higher rate.


    This is captured in the attached image where the red/ blue dots represent advertisements received from two devices.


    The same application running on a gen 1 Surface Book with the same OS build does not behave this way: The application consistently receives advertisements at the normal higher rate.

    So there is almost certainly some Windows setting somewhere that is causing the OS to throttle the rate at which it delivers advertisements to applications while the Lenovo is in active use.


    Can someone please tell me what that setting is?


    One difference between the laptops is the BLE driver:


    Lenovo: IntelR Wireless BluetoothR; DriverVersion=21.110.0.3
    Surface: Marvell AVASTAR Bluetooth Radio Adapter; DriverVersion=15.68.17018.116


    Thanks.


    Dev.

    Bluetooth in windows 10

    My computer specs are as listed in the profile. I think all of you guys are correct. I don't have built-in Bluetooth in mobo.

    I contacted skull candy headphones and thy have told me if I do not have built-in Bluetooth, I would need a dongle which supports at least a2dp. I do not know what the heck that means. I have a feeling I would need more than a cheap dongle.

    Anyone suggest some a2dp adapters. I searched but don't know what a2dp is so couldn't make a decision

    Bluetooth Technology Gets Faster With Bluetooth 3.0

    From its annual All Hands Meeting in Tokyo this week, the Bluetooth SIG formally adopted Bluetooth Core Specification Version 3.0 + High Speed (HS), or Bluetooth 3.0. This latest iteration of the popular short-range wireless technology fulfills the consumers' need for speed while providing the same wireless Bluetooth experience – faster. Manufacturers of consumer electronics and home entertainment devices can now build their products to send large amounts of video, music and photos between devices wirelessly at speeds consumers expect.
    Bluetooth 3.0 gets its speed from the 802.11 radio protocol. The inclusion of the 802.11 Protocol Adaptation Layer (PAL) provides increased throughput of data transfers at the approximate rate of 24 Mbps. In addition, mobile devices including Bluetooth 3.0 + HS will realize increased power savings due to enhanced power control built in.


    "Like Ricky Bobby in Talladega Nights, this latest version was 'born to go fast,' said Mike's Blog, Ph.D., executive director of the Bluetooth SIG. "Utilizing the 802.11 radio was a natural choice as it provides efficiencies for both our members and consumers – members get more function out of the two radios they are already including in devices, and consumers with Bluetooth 3.0 + HS products will get faster exchange of information without changing how they connect. We are excited to expand the possibilities of the PAN."

    This newest version of Bluetooth technology builds on the inherent qualities of the current 2.1 + EDR version, including Simple Secure Pairing and built-in, automatic security. And as with all versions of theBluetooth specification, v3.0 + HS provides developers, manufacturers and consumers with the benefit of backwards compatibility, enabling both the expansion and enhancement of this technology with every new specification release. Once products reach the market, the easiest way for consumers to learn which devices are compatible with other Bluetooth enabled devices is to visit the Bluetooth Gadget Guide.

    Applications
    With the availability of Bluetooth version 3.0 + HS, consumers can expect to move large data files of videos, music and photos between their own devices and the trusted devices of others, without the need for cables and wires. Some applications consumers will experience include:
    • Wirelessly bulk synchronize music libraries between PC and music player or phone
    • Bulk download photos to a printer or PC
    • Send video files from camera or phone to computer or television
    Availability

    The Bluetooth SIG's formal adoption of the specification is only the first step in the product lifecycle. News out today from wireless chip manufacturers and Bluetooth SIG member companies Atheros, Broadcom and CSR shows the second step – getting silicon solutions to device manufacturers – is already underway. End products for consumers are expected to be in the market in 9 to 12 months.

    Technical Specifications
    This new specification release includes several major enhancements (learn more here - page requires member login):
    • Generic Alternate MAC/PHY (AMP)
    • 802.11 Protocol Adaptation Layer (PAL)
    • Generic Test Methodology
    • Enhanced Power Control
    • Unicast Connectionless Data
