Мышь Волшебства Apple часто разъединяется и снова соединяется

У меня была та же проблема, и недавно я попытался отключить eSCO режим в модуле Bluetooth:

echo 1 | sudo tee /sys/module/bluetooth/parameters/disable_esco
sudo /etc/init.d/bluetooth restart
# persist setting
echo "options bluetooth disable_esco=1" | sudo tee /etc/modprobe.d/bluetooth-tweaks.conf

Соединение мыши кажется более стабильным теперь, и я не видел разъединение после тонкой настройки этой установки.

Моя Lenovo W530 ноутбука имеет адаптер Bluetooth Broadcom (внутренне, usb является интерфейсом).

Если у Вас есть адаптер Bluetooth Broadcom, Вам, возможно, придется получить .hex микропрограммный файл от драйвера окон и поместить его в/lib/firmware каталог, чтобы поддерживать все функции Bluetooth. Больше информации в https://bugs.launchpad.net/ubuntu / + источник/Linux / + bug/1065400/comments/11 и https://bugs.launchpad.net/ubuntu / + источник/Linux / + ошибка/1065400.

Используйте hex2hcd для преобразования драйвера окон .hex файл к .hcd: https://github.com/jessesung/hex2hcd

Я нашел Broadcom .hex файлами в этом пакете драйвера окон. Найдите Win7/Win32/bcbtums-win7x86-brcm.inf файл и поиск идентификатора USB Вашего адаптера.

$ lsusb |grep Bluetooth
Bus 001 Device 006: ID 0a5c:21e6 Broadcom Corp. BCM20702 Bluetooth 4.0 [ThinkPad]

поиск RAMUSB<usb product id in upper case>, например, RAMUSB21E6 для моего адаптера. Там Вы найдете .hex имя файла:

[RAMUSB21E6.NTX86.hw.reg]
HKR,,LowerFilters, 0x00010000, "bcbtums"
HKR,,%RAMPatchFileName%,0x00000, "BCM20702A1_001.002.014.1315.1387.hex"
HKR,,%RemoteWakeEnabled%,0x00010001,1
HKR,,%DeviceRemoteWakeSupported%,0x00010001,1

В моем случае файл был Win7/Win32/BCM20702A1_001.002.014.1315.1387.hex

Я затем использовал hex2hcd для преобразования файла в/lib/firmware/fw-0a5c_21e6.hcd (снова, что имя файла содержит идентификаторы USB USB Broadcom адаптер Bluetooth).

Я считаю, что правильным решением является следующая правка в /etc/bluetooth/main.conf:

[General]

# Default adapter name
# Defaults to 'BlueZ X.YZ'
Name = BlueZ

# Default device class. Only the major and minor device class bits are
# considered. Defaults to '0x000000'.
Class = 0x000100

# How long to stay in discoverable mode before going back to non-discoverable
# The value is in seconds. Default is 180, i.e. 3 minutes.
# 0 = disable timer, i.e. stay discoverable forever
DiscoverableTimeout = 0

# Always allow pairing even if there are no agent registered
# Possible values: true, false
# Default: false
AlwaysPairable = false

# How long to stay in pairable mode before going back to non-discoverable
# The value is in seconds. Default is 0.
# 0 = disable timer, i.e. stay pairable forever
PairableTimeout = 0

# Use vendor id source (assigner), vendor, product and version information for
# DID profile support. The values are separated by ":" and assigner, VID, PID
# and version.
# Possible vendor id source values: bluetooth, usb (defaults to usb)
DeviceID = bluetooth:1234:5678:abcd

# Do reverse service discovery for previously unknown devices that connect to
# us. For BR/EDR this option is really only needed for qualification since the
# BITE tester doesn't like us doing reverse SDP for some test cases, for LE
# this disables the GATT client functionally so it can be used in system which
# can only operate as peripheral.
# Defaults to 'true'.
ReverseServiceDiscovery = true

# Enable name resolving after inquiry. Set it to 'false' if you don't need
# remote devices name and want shorter discovery cycle. Defaults to 'true'.
NameResolving = true

# Enable runtime persistency of debug link keys. Default is false which
# makes debug link keys valid only for the duration of the connection
# that they were created for.
DebugKeys = false

# Restricts all controllers to the specified transport. Default value
# is "dual", i.e. both BR/EDR and LE enabled (when supported by the HW).
# Possible values: "dual", "bredr", "le"
ControllerMode = dual

# Enables Multi Profile Specification support. This allows to specify if
# system supports only Multiple Profiles Single Device (MPSD) configuration
# or both Multiple Profiles Single Device (MPSD) and Multiple Profiles Multiple
# Devices (MPMD) configurations.
# Possible values: "off", "single", "multiple"
MultiProfile = off

# Permanently enables the Fast Connectable setting for adapters that
# support it. When enabled other devices can connect faster to us,
# however the tradeoff is increased power consumptions. This feature
# will fully work only on kernel version 4.1 and newer. Defaults to
# 'false'.
FastConnectable = false

# Default privacy setting.
# Enables use of private address.
# Possible values: "off", "device", "network"
# "network" option not supported currently
# Defaults to "off"
Privacy = off

[GATT]
# GATT attribute cache.
# Possible values:
# always: Always cache attributes even for devices not paired, this is
# recommended as it is best for interoperability, with more consistent
# reconnection times and enables proper tracking of notifications for all
# devices.
# yes: Only cache attributes of paired devices.
# no: Never cache attributes
# Default: always
Cache = always

# Minimum required Encryption Key Size for accessing secured characteristics.
# Possible values: 0 and 7-16. 0 means don't care.
# Defaults to 0
KeySize = 0

# Exchange MTU size.
# Possible values: 23-517
# Defaults to 517
ExchangeMTU = 517

[Policy]
#
# The ReconnectUUIDs defines the set of remote services that should try
# to be reconnected to in case of a link loss (link supervision
# timeout). The policy plugin should contain a sane set of values by
# default, but this list can be overridden here. By setting the list to
# empty the reconnection feature gets disabled.
ReconnectUUIDs=00001112-0000-1000-8000-00805f9b34fb,0000111f-0000-1000-8000-00805f9b34fb,0000110a-0000-1000-8000-00805f9b34fb

# ReconnectAttempts define the number of attempts to reconnect after a link
# lost. Setting the value to 0 disables reconnecting feature.
ReconnectAttempts=7

# ReconnectIntervals define the set of intervals in seconds to use in between
# attempts.
# If the number of attempts defined in ReconnectAttempts is bigger than the
# set of intervals the last interval is repeated until the last attempt.
ReconnectIntervals=1,2,4,8,16,32,64

# AutoEnable defines option to enable all controllers when they are found.
# This includes adapters present on start as well as adapters that are plugged
# in later on. Defaults to 'false'.
AutoEnable=false

Это отлично работает для меня.
