Wireshark does not detect BLE messages between peripheral BLE UARTs and central BLE UARTs

Question

Premise: wireshark I had used it about two years ago with another PC with WIN7 and with other versions of SW. 
 The dongle is the same as two years ago and is the dongle with nRF51. 
 Now you are using a PC with WIN10 64 bit. 
 To update all the required SW I refer to this link: https://infocenter.nordicsemi.com/index.jsp?topic=%2Fug_sniffer_ble%2FUG%2Fsniffer_ble%2Finstalling_sniffer.html 
 I have successfully performed all the required operations. 
 Once the wireshark program has been started and the sniffer started, the advertising signal from BLE peripheral is displayed (BLE central is OFF). 
 Once the connection between BLE central and BLE peripheral is started and the data exchange between wireshark no longer detects the advertising signal from BLE peripheral but does not display any BLE communication frame. 
 If I open a log file saved two years ago with wireshark, I see the information regarding the data exchange correctly displayed. 
 How can I solve this problem ? 
 I await your kind reply.

Hello Karl. 
 I solved the problem. The reason was due to the sniffer version downloaded on the nrF51 dongle (PCA10031). With the latest version of "sniffer nrf_sniffer_for_bluetooth_le_4.1.0" it doesn't work. If I try to use an eval nRF52dk (PCA0040) as a siniffer it doesn't work the same. The sniffer works perfectly ONLY with the version "nrfsniffer200beta312oct20181c2a221" and with the EVAL nRF52dk. With the nRF51 dongle (PCA0031) it still does not work. 
 I can conclude that my nrF51 (PCA10031) dongle is obsolete. Which nRF dongle do you recommend to buy in order to use the latest version of sniffer "sniffer nrf_sniffer_for_bluetooth_le_4.1.0" ? 
 
 Thanks.

Hello Karl, thank you for your support. What you suggested I do doesn't work. Any selection made on "Device" does not display the data exchanged via BLE and I continue to see only the advertising data of the other connected BLE devices. I added filters to check if data frames arrive without seeing any results. What is missing ? I thank you.
