@mobi: As mentioned above, you would need to combine the 2 example, first one is the Gazell examples in the SDK, second is the uart example also in the SDK.

You don't have to use gzp_desktop_emulator_arm. It's made for the mouse and keyboard. You can simply use the gzll_ack_payload example.

Got it. So by default the dongle doesn't support gazell. One small question to test, gzp_desktop_emulator_arm will run on our custom board. Is there any example available which I will flash on USB dongle ? I guess I have to add UART to support to that to send data to USB/COM port ...

@mobi: I'm pretty confused. You mentioned "I expected that when I run nRF Master Control Panel application on PC, it should see the device but It didn't."

The master emulator firmware on the dongle doesn't support gazell. It only supports BLE.

You would need to write your own code for gazell. You can have a look at the gazell example. Combine it with UART interface, and send the data it receive to UART port on the PC.

Our custom NRF51822 Board is working fine. We also have android app which connects and works fine. Master Control panel app also works fine with our custom board and BLE services. We are pretty good with BLE protocol.

We have trouble setting up gazelle and testing it out on the PC Side ... Please guide us on this.

@mobi: I would suggest you to test your board functionality first to make sure it works. Please start with the ble_app_hrs example. After you flash the board (remember to flash the softdevice) you should use nRF Master Control panel and check if it's advertising. Note that if you don't have 32kHz crystal on the board, you would need to use NRF_CLOCK_LFCLKSRC_RC_250_PPM_4000MS_CALIBRATION instead of NRF_CLOCK_LFCLKSRC_XTAL_20_PPM when calling SOFTDEVICE_HANDLER_INIT() in main.c

If it doesn't advertise please verify that the board can work properly, you can start with blinking an LED.

Please see the Edit portion of the question and please guide us on the setup process ...

@mobi: You can use another nRF51 DK board to retreive the data. Then you can send the data to PC via the virtual COM port created by the USB connection. We already have gazell example in the SDK, you just need to forward the data to UART port.
