People at my work have been given written warnings for using a Bluetooth mouse. We have security teams doing site visits with scanners and if they catch anyone using unauthorised gear there is hell to pay.
Iāve been with the company for 26yrs now and itās only been the past 18 months Iāve been allowed to use a BT mouse and keyboard on my laptop, and I had to buy specific ones from the company portal that have been approved.
Our Security team obviously seem to think the danger is real.
Probably not, as Iāve never seen a RK3288-based embedded computer with socketed wifi module. Itās Integrated/soldered to the main board.
Such a stupid answer ! The two dongles you show are receivers ! How do you send something to a bluetooth speaker with a receiver plugged on a usb port ?? 
Denon choose to not activate bluetooth on P4 probably because the chip was 3 or 4 version. I think that it would have been a good thing for P4 owners to have this update working, even with āold bluetooth versionā. A smartphone doesnāt need Bluetooth 5 to communicate when it is just beside the gear. One question now : Do we have to update Prime 4 to 3.4 if it doesnāt bring anything ? Or stay in 3.3 since Denon thinks that P4 is obsolete and wonāt receive updates anymore ?
I believe updating is always a good idea, updates always bring some under the hood bug corrections and improvements.
I also believe SC5000s, P4 and P2 will continue to receive updates 
Not according to the kangaroo court that is the internet 
And our little French friend above lol.
Pardon me for not using the ācorrectā photo. The point was the packaging, not the specific units shown. My mistake for assuming youād be smart enough to figure that out. Guess thereās a lot of stupidity to go around?
Guess what ? What is stupid is pretending to be smart enough for giving lessons, and posting the wrong pictures lol !
Thinking the Prime 4 is now stuck on 3.3.0 and will be obsolete is also up there in the stupid stakes too tbf.
Lol ! Thatās not my name but yours wich is the half of the word STU-pid on this forum 
the other part taken by your pathetic ābrotherā pasha. Heckel & Jeckel. Seems you have a lot of ennemies here seen the number of clashes with many membersā¦ Already told you : Mind your own business and get a life. Donāt speak to me anymore. Youāre not clever enoug or real dj for that. So now what youāre gonna do ? Youāre gonna flag my post once more like the little child that you are, crying in modās pants ?
Youāve already been told by the mod previously that I donāt flag your posts, and youāre still weeping about it.
Iām just here to correct your silly little assertions that you have a habit of projecting, and are almost always embarrassingly incorrect.
Itās quite a skill being so wrong about so many things all the time.
As for being a real DJ, at least Iām not using the name of well known cheesy French pop DJs because Iām too cowardly to reveal my identity on the internet.
And for the record, Iāll be back here to let you know you got it wrong again when the next update comes and the Prime 4 is still not obsolete. So remember this post, and we expect an apology.
All work perfecto thank you. Now, see the wave of the song 
Una maravilla de actualizaciĆ³n, ahora falta poder ver la onda
yes, sweep FX would be nice to have on the bluetoothās channel
Merde, the french are frenching again 
Touch FX work on the BT audio, maybe that is enough?
Moin @STU-C,
despite the fact of hypothetic cyber attack risks here are discussed, via a stand alone controller (e.g. Prime 4) with integrated WLAN (WiFi) and which is furthermore integrated in a network and therefore Iām most delighted that you point out that are risks of cyber attacks and we should be aware of these risks. Thank you for your advise.
Iām glad being advised. Another point will be, how to handle the risk and it is every userās own decision to handle or not

Iām not overly familiar with the Prime 4 but does it not have phono/aux inputs for channels 3 & 4? - Could you not just use a Ā£10 bluetooth receiver/transmitter to send audio via bluetooth to those channels? Granted the transport controls and screen displays wouldnāt work but the EQ and hardware effects would surely?
There is no more French than a Frenchman (and I am French)
However, it always makes me laugh to see certain people (French or not) getting lost in conjecture and speculation about the fact that equipment that has not received BT will no longer be updated in the futureā¦
The poor risk once again making fools of themselves in a short time
Device sometimes hangs in loops after update. It only goes away by turning off the console.
Hi, BT? Mostlikely never gonna use it. Features like to add rating and change tags from the hardware, would be a greater benefit for those who seek more efficient workflow.
