I ve installed CSR bluetooth 4.0 adapter , it can communicated with even the bluetooth 2.0 devices, how ever it even can not discovery the board when I programed the softDevice and project under s110. what is wrong?
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.
