puck.js: advertisement not working !!! Need help

Hi
I've updated the firmware to the latest version 2.v04
Then I've reloaded the service as above.
Connecting with Nrf Connect (android) I can see as you the 0x181A sensing service

Then in the documentation they mention that the advertisement cannot be seen outside of a connection
So running my sniffer I've connected to the puck.js from NrfConnect
I can see The CONNECT_REQ then various Read-by-group req to discover the GATT characteristiques
then a bunch of empty PDU to maintain the connection open I guess.
But no adverstisement at all
At the end I get again the ADV_IND with just the device Name

I suspect an issue somewhere or an error in the doc or a wrong usage ?

Any idea and help ?

Thanks a lot
