Small size is not a problem, for example XR21V1410 in QFN16 and a few external R and C. It will be seen on PC as COM-port and will use standard driver.

Hi Nikita, costs not very important, the small size and free of driver by USB-HID is what the client liked.

You can use nRF51822 + USB-UART bridge like FT232R or any other. Though it'll increase the cost.

Hi Nikita, Thanks a lot I think if the chip supplier of 4.0 adapter offer driver API even the XP can work too. unfortunately they not offered yet. may be they will offer in near future. So now what I do is make my own dongle? may be I can try to use 2540 to make a dongle and use 518 to make devices, the 518 not offer USB driver.crazy work.

Though even HID is not supported by some USB Bluetooth 4 adapters in Windows 7. See this: devzone.nordicsemi.com/.../

It's regarding general USB Bluetooth 4 adapter. But you can made custom USB dongle that will be seen in windows as USB HID or USB CDC with virtual com-port and you can communicate with dongle through custom HID driver or serial port. In this case nRF51822 in this dongle need to be central (see S120 examples from SDK) and connect to your device (peripheral with S110 and custom service) if it discover it advertising. Once dongle connect to your device it'll communicate through custom service.

The thing is Windows 7 doesn't support Bluetooth 4. But you can use Windows 7 + USB Bluetooth 4 dongle with special drivers from manufacturer that support some of the profiles. Bluetooth 4 don't have serial port profile so you can't easily communicate with Windows through virtual COM-port. The only way you can communicate between your device and windows is to use custom HID profile. For this you need to get HID keyboard example from Nordic SDK: nRF51 SDK_v6.0.0.43681\Nordic\nrf51822\Board\nrf6310\s110\ble_app_hids_keyboard and rewrite it to use custom HID service. Next you need to write windows driver to communicate with your custom HID service.

Hi Nikita, thank you very much , but I am not welcomed to decide client use which system, xp, 7, or 8. the first way is client can plug in a general usb blue4.0 adapter if they do not have bluetooth 4.0 function in their computer. the second way may be we can offer a special USB dongle for them,but that will add costs. first way is best as it is most convenient for clients. the difficulty is I can not find a bluetooth4.0 BLE SDK to driver the adapter and communicate with 4.0 devices. now I can find a bluetooth SDK from bluesoil, it can scan the HRM devices, but it do not offer interface to communicate with BLE devices. it only support SPP and OPP protocal. If I can find a SDK of BLE for windows that will be wonderful.

the second way can be done too,similar to Btool or Sniffer, but we must design protocal of central control device to scan and communicate BLE devices, also we need to design interface communicate with computer software, that will be challenge work too, as I do not have much experiences about BLE. if I can find some sample projects that may help much.

Do you need Windows 7 support for your device or just Windows 8 and later will be acceptable?

the hardware device I need to communicate computer with BLE must easy to buy or offer to client. also the computer communication of software design should be as easy as possible.

Hi Nikita, I never use ble USB dongle from nordic, I only use USB bluetooth 4.0 adapter from CSR in market. in bluetooth 2.0 , I can easy to use spp to send datas to the bluetooth devices in my computer software, but now I do not know how to design my computer software to control these ble devices. by the way , I can not buy ASUS BT400 here.

First figure out why you can't see any other projects. I think HID KB must be discovered on WIndowsin any case. What windows version are you using? Maybe try to change USB Bluetooth dongle, I have Asus BT400 and it works fine in Windows 7.

If you have board 10001 then you have nRF51822 Evaluation kit, right? This one: www.nordicsemi.com/.../nRF51822-Evaluation-Kit And there is small USB dongle in this kit that is PCA10000. Well, if you don't have this dongle for some reason, then try to find some Android/iOS device with bluetooth 4 support and try to test if it'll see your device.

I do not have dongle from nordic, I ve installed CSR drivers, very big files.

Nikita — Fri, 22 Aug 2014 03:19:57 GMT

Can you connect to your device with dongle from Nordic kit (if you have one) of from Android/iOS device? Did you install standard drivers for this CSR adapter or specific drivers from manufacturer?

The example projects worked? Was there some response from buttons/leds? LED0 is blinking on power up?

What board do you use? What project do you use? Try to flash and check HID keyboard example project.
