Wireless Carplay looses iPhone Mobile Connectivity

[dbullfrog]

A weird problem that I'm not finding a solution to in the apple Iphone forums, and wonder if anyone here has solved the same issue?

apple WIreless Carplay connects the Iphone to the NX 450+ using both Bluetooth and Wifi because of the bandwidth needed.  So far so good.  However, when the phone connects to something with WiFi it looks to the WiFi to provide internet connectivity, which of course the NX 450+ doesn't have.  The phone itself still has a 5G connection and plenty of bandwidth, but it seemly ignores it and when I try to use any ap that needs internet connectivity it just says it has no connectivity.

From the apple forums this seems to be a known problem, but the solutions I've seen mean mucking about with IP addresses or deep iPhone  settings that I'd rather not mess with in case it screws something else up.

The simple fix is I've dropped the Bluetooth pairing between my phone and the car and gone back to a wired connection with the front USB A port.  Everything works swimmingly, but it seems to defeat the purpose of wireless carplay and charging. 

Has anyone else come up with a solution either with the NX' settings or on their Iphone?

I think if you are using wireless CarPlay you can not be connected via Bluetooth as well. It’s either one or the other.

Hi!  Hardcore techie here.  Its quite slick actually.  When you enter the car, there is a handshake between the car and the Iphone over Bluetooth, basically securely recognising each other, this then initiates the WiFi connection.  You are absolutely correct that the data then flows over WiFi but I believe you'll still be able to find that your phone shows that it is connected via Bluetooth, even if the connection is no longer used.

Indeed, that I think is the root of the problem.  The Iphone thinks its fully connected over WiFi, and doesn't understand it can't get internet bandwidth that way.  Maybe its just my Iphone, hence wanting to see if anyone else had encountered the problem or found a solution!
