Windows 7 Gatt service support

[Anonymous]

I have developed firmware/hardware for the bcm 920732 that supports 0x1800, 0x1801, 0x1802, 0x180A, and a vendor service. Can interact with them OK on Win 8 and can see them on Win 7 but dont know how to interact with them  on Windows 7, do you have a GATT api that runs on Windows 7?

It sounds like you developed a custom service using our BCM20732S WICED Module (or are you using the 20732 SOC?) and would like to build a client application under Windows 7 that communicates with the service running on the BCM20732. Is my understanding correct?  Since Windows 7 does not support 4.0/BTLE natively, a third party BT stack extension will be required.The Broadcom Bluetooth Drivers are online here: http://www.broadcom.com/support/bluetooth/update.phpAnd partners like Plugable build USB dongles and drivers based on our BCM20702 that add features like HID over GATT: http://plugable.com/products/usb-bt4leI will check with the SW team on specific API/Application support we can provide for Windows 7.

If you have Broadcom radio installed on Win7 machine (check properties of the Bluetooth radio in the device manager) there is a way to do a GATT client application.  SDK provides a sample which works on both Win7 and Win8 under WICED-Smart-SDKAppsRAMhello_sensorHelloClientWindows.  The btwleapis.h has a decent documentation.  If you do not have Broadcom radio, you can buy one.  Make sure that it is Bluetooth 4.0 and it mentions WIDCOMM stack somewhere in the documentation or reviews.  I used couple from http://www.amazon.com/gp/product/B009ZIILLI/ref=oh_details_o01_s00_i00?ie=UTF8&psc=1 and http://www.amazon.com/gp/product/B004LNXO28/ref=oh_details_o03_s00_i00?ie=UTF8&psc=1.  Please note that you will need to disable internal radio to use a dongle.
