Работа с WeDo 2.0 (арт. 45300) под управлением Windows 7.

Важно знать, что для работы WeDo 2.0 необходима поддержка технологии связи Bluetooth с низким энергопотреблением (Bluetooth Low Energy (сокращённо — BLE)). Устройства под управлением Windows 7 обычно выпускаются без поддержки технологии BLE. BLE следует рассматривать как отдельную технологию, отличную от более широко известной технологии связи Bluetooth. Единственное устройство с технологией BLE, поддерживаемое Windows 7, — рекомендуемый к использованию внешний адаптер Bluegiga Bluetooth Low Energy модели BLED112. Никакое другое оборудование BLE для WeDo 2.0 в среде Windows 7 не поддерживается.
Как настроить работу WeDo 2.0 в системе под управлением Windows 7:
Шаг1. Подключите донгл USB BLE () в любой USB порт вашего ПК. Рекомендуется сделать это перед тем, как запускать установщик ПО WeDo 2.0.
Шаг2. Донгл определится системой, как Generic BLE Device. Это абсолютно нормально. В отдельных случаях может определиться полное название устройства.
Шаг3. Запустите установку ПО WeDo 2.0. Следуйте инструкциям программы установки, пока на экране не появиться просьба перезагрузить компьютер. Если система попросит вас подтвердить установку драйверов от стороннего производителя, вам требуется подтвердить это.
Шаг4. Установка драйвера может осуществляться несколькими способами:

— PnPutil
Утилита Microsoft PnP, интегрированная в Windows.- DPinst
Мастер установки драйверов, входит в состав утилиты по работе с драйверами Windows.
Во время установки ПО WeDo 2.0.Мы рекомендуем перезагрузить компьютер после установки ПО и драйвера донгла BLE.

Шаг5. Запустите ПО WeDo 2.0 после перезагрузки ПК, теперь вы можете подключить СмартХаб WeDo 2.0.

BLED112 Bluetooth Low Energy Dongle

At WWDC last year I went to a pretty interesting Core Bluetooth 101 session (link requires an Apple Developer account) that covered the Bluetooth Low Energy capabilities of iOS. Prior to the session, I had no idea that newer iOS devices can communicate with other devices and systems via Bluetooth LE without requiring an MFI license from Apple. The iPhone 4S, iPad 3 and all newer devices ship with a Bluetooth 4.0 radio that supports BLE.

Since then, I’ve been mulling over some ideas for projects with Arduino or Raspberry Pi communicating with iOS so I bought a Bluegiga BLED112 Bluetooth “integrated stack” dongle for $35 from The BLED112 is pretty small and feels a little fragile — its also a tight fit in most USB slots that I tried so I use mine by connecting it to an old Apple Keyboard USB extension cord. You can get similar small USB extension cords on Monoprice for less than a dollar and I’d recommend it as you will have to reboot the dongle during development (lots of plugging and unplugging).

My dongle shipped with a “thermometer” profile built in and was running v1.0.3 of the Bluegiga API (BGAPI). A quick dig around the Bluegiga forum (free registration required) and I upgraded to the latest “beta 2” build v1.1.0 which offers improved speed and stability.

Installing the BLED112 drivers in Windows

Although the BLED112 acts as a serial port when connected to Mac / Linux etc. it will require you to install drivers to interact with the dongle on Windows if you want to upgrade the firmware or install your own BLE GATT profile. I followed the following process on a Windows XP VMWare instance on my Mac to get the tools up and running:

Download the Bluetooth Smart v.1.1.0 beta 2 Software Development Kit from Bluegiga and unzip the SDK to your C: drive — it will create a directory structure starting at C:\ble\
Connect the BLED112 dongle to your USB port
Windows will detect the new hardware and will prompt to install drivers — the regular dongle drivers are here: C:\ble\windrv\
Once installed, the dongle will appear as a COM port called “Bluegiga Bluetooth Low Energy (COM X)” under Windows Device Manager.

Upgrading the BLED112

The docs on Bluegiga are pretty extensive but I found them a little tricky to navigate, so I’ve outlined the steps I followed here to upgrade my v1.0.3 dongle to the latest v1.1.0 (beta):

Note: these instructions require Windows and this kind of firmware update can brick the dongle — follow at your own risk!

Install the dongle under Windows as above
Launch the Bluegiga BLEGUI application from: C:\ble\bin\blegui2.exe
In the BLEGUI main window, select “Bluegiga Bluetooth Low Energy (COM)” from the drop down at the top of the screen
Click the “Attach” button to attach BLEGUI to the dongle
Now we need to put the dongle into Firmware Update mode — in the BLEGUI menubar select “Commands -> DFU” which will reboot the dongle in DFU mode
Windows will now detect the dongle as a new kind of USB device (it’ll show as a libusb (WinUSB) device in Device Manager) and will prompt you again for drivers — the DFU drivers are in the same location as the Windows drivers above: C:\ble\windrv\
Once the drivers are installed, we now need the USB Vendor ID (VID) and Product ID (PID) of the dongle in DFU mode — this should be the same for you as it was for me, but to be sure navigate to the “libusb (WinUSB)” section of Device Manager and double-click the dongle. Under the description tab you should see a string that looks like “USB\VID_2458&PID_FFFE\1234” — this would give you a VID of 2458 and a PID of FFFE:
We’re now ready to flash the new firmware from the Windows command line so launch a cmd window (Start -> Run… -> cmd)
The v1.1.0 firmware file will be in the following location: C:\ble\example\usbcdc\out.hex
From the command line type the following to navigate to the firmware and flash to the dongle:

cd \ble\example\usbcdc\ ..\..\..\bin\dfutool 2458:fffe out.hex

The new firmware will be written to BLED112 and if all goes well once the write hits 100%, the dongle will reboot in regular COM mode and Device Manager will refresh to show the dongle under the COM / LPT Ports section.

Using Silicon Labs BLED112 module with Bluetooth Framework

The Silicon Labs BLED112, Bluetooth low energy USB Dongle is a single mode USB device enabling Bluetooth low energy connectivity for PC’s and other devices having a USB port.

BLED112 Bluetooth Dongle integrates all Bluetooth 4.0 single mode features. The USB dongle can simulate virtual COM port. The COM port emulation enables simple host application development using Bluetooth Framework on any Windows OS.

Once plugge BLED112 appears as a COM port in the system. Windows 10 and above installs the BLED112 driver automatically. Windows XP, Windows 7 and sometimes Windows 8 do not install the BLED112 driver automatically and you need to download and install it manually. You can find the BLED112 driver by this link: BLED112 Windows Driver. Or directly from our site. You do not need any additional SDKs to be able to use BLED112 Bluetooth USB dongle with Bluetooth Framework.

As BLED112 is the single mode Bluetooth Low Energy module it does not support any Bluetooth Classic features. BLED112 can be used to connect to GATT Client, to discover Bluetooth LE devices, to capture Bluetooth LE advertisements, to LE advertising and to BLE pairing (passkey notification and passkey request pairing are only supported).

Should you have any questions about using BLED112 with Bluetooth Framework please do not hesitate to contact us.
