HID needed to recognize BLE uart on windows ?

I get Puck.js connected without problems.
Sometimes I've to drop and reconnect, but it works fine.

Please see here http://www.jumware.com/JUMSpruino/problems/Bluetooth_ESP32.html
for some screenshots and a video

nRF connect gives same raw data for advertising as Puck.js does, except the name ;-)
nRF UART v2.0 connects, sends data and receives data.

Under windows (changing the name to Espruino doesn't change anything)

• admin page for adding bluetooth devices finds the ESP32 device
  
• - after click on device "establish connection" is shown (my translation)
  
• - some seconde later "try again" is shown
  
  

With Puck.js I've to do the same and it connects. And next Puck.js is available for IDE
