Wireshark doesn't see nrf51 dongle sniffer

The 'JLink CDC UART Port (COM3)' is listed in the Device Manger.

Running as Admin doesn't change the outcome.

It seems to me that there is a problem with the virtual COM port on this specific PC, as the software runs on other PCs. The same problem occurs with unrelated software, so I think it's fair to close this case.

Hi,

[quote user="Han Vertegaal"]Could it be that the programmer bypasses the COM port emulator and talks directly to the USB?[/quote]

As your thought, the programmer app communicates through the Jlink interface while the BLE app communicates through the VCOM.

You could try to run nRF connect as admin since the error says "access denied", and also check if the JLink COM port is listed in the "Device manager".

Sorry for the delay. I tried, but the problem remains.

Do you have an idea about the difference between the BLE app and the programmer where it comes to communicating with the device. Could it be that the programmer bypasses the COM port emulator and talks directly to the USB?

Hi Han,

Could you try other USB ports and do the Vidar's suggestion again?

I erased the dongle using the programmer. Then started BLE, but I got the exact same log (error opening COM3). Next, I reprogrammed the device so I can user it as a sniffer again on my other PC. Reprogramming worked fine. Next, I started BLE again, and it prompted me that the dongle needed to be reprogrammed. Clicking Ok in the dialog resulted in the following log:

Looking at the memory map using the programmer, it seem that the BLE app did indeed program a new image, but subsequently failed to connect.

Apparently, if the BLE app communicates through J-Link (as does the programmer) everything works, but when it accesses the COM3 port directly (?) it fails.

Hi Han,

Please try Vidar's suggestion in this post.

I tried resetting the dongle, but that brings no change.

Hi,

If you can program the nRF51 dongle with nRF Connect Programmer, you suppose to could use nRF51 dongle with nRF Connect BLE.

Did you also press the reset button on nRF51 dongle before connecting with nRF Connect BLE as using nRF Connect Programmer?

If it still cannot work after pressing the reset button then connecting, could you provide the log of nRF Connect BLE?

In the mean time I installed nRF Connect BLE, and saw that it couldn't open the COM port on which the dongle operates. Because other software also has problems opening COM ports over USB, I conclude it is not so much an nRF software problem as a problem with my PC. So I re-installed everything on another PC and now it works fine, Wireshark and everything. Problem solved.

However, I can still program the dongle using nRF Connect, and I assume it uses the same USB attached COM port. What is the difference between nRF Connect Programmer and nRF Connect BLE? One of them works fine, while the other does not.
