Using nRf programmer app write new .hex file to the dongle. have taken .hex file from the nrf_sniffer_for_bluetooth_le_4.1.0 file.

1. Open programmer App

2. Connect the dongle to the PC

3. Reset the dongle

4. Red led is blinking in dongle

5. Select the dongle in drop down

6. Add .hex file

7. Click on Write hex file

Observing result: Getting timeout error after writing 100%

Hi, 

That is the expected behavior. The device will reset when the upgrade completes and the dongle will no longer show up in nRF Connect unless the application used DFU Trigger Library is used, as it is no longer in DFU mode. You will get an error stating "Reopen device failed" in this case, and have to push the RESET button in order to make it show up in nRF Connect Programmer again.

Now i can able to see the advertisement, but LEDs are not blinking once select the capture option in wireshark tool.

Steps:

1. Open wireshark tool

2. Connect nRf dongle

3. Go to Capture >> refresh interface

4. Select nrf dongle

5. Select start capture

Current result: Green LED is stop the Blinking and not showing any data in capture page, and need to refresh again the  refresh interface in wireshark tool to get turn on the sniffer

Let me know why nRf sniffer is moving to sleep mode??

1. Open wireshark tool

After opening Wireshark, LED 1 should be on. You will see the nRF Sinffer for dongle presented as the following figure. Double click it to start capturing.

Replug the dongle and Reopen Wireshark. The LED 1 on the dongle will light with Green when they connect.
