Slowness on BMW Connected App

I’m new to remote features on vehicles since it has been over a decade since I bought new.

Although the BMW Connected app has some cool features, I find the performance extremely slow.

Rendering of the 3D view takes several minutes and even honking the horn takes longer than I would expect in 2020.

Is this normal behavior?

I can typically complete a remote 3D view in around 60 seconds here in the UK, but occasionally longer - there can be many factors which will impact how long it takes, not least of which is the wireless service which the car happens to be connected to at the time you make the request (something you have zero control over).
Connected Drive isn't excessively slow, but at the end of the day you are doing a "secure" communication with your car over multiple networks, some of which BMW can't necessarily predict or control.

Just did a wee test, and it took 11 seconds to complete the "light flash" (car is sitting in the drive and I can see it through the window).
I can't complain at that kind of response, considering what's actually happening behind the scenes.

Mine is no where near that. Horn honk took 20-30seconds.

The remote cam refresh takes several minutes.

I guess it’s the cell service

Remote 3D view has always taken 60-90+ seconds for me... (not quick, but pretty cool!)

Just timed the 3D view under the same conditions as above. Took 72 seconds from pressing Refresh to seeing the image on my phone.

11 seconds is like ages in terms of data communication. The protocol that is being used must be not so efficient (probably because of security rules) which is causing this speed.

Basically the App needs to send a single packet with the instruction (say open locks, close locks, flash lights, etc) and wait for the acknowledge coming back from the server.
In data transmissions speeds you will get easily something <100ms for a packet like this to go between your smartphone and the mobile network, then add let's say another 200ms if you have to travel the whole world (let's say you are in US and talking to a server in Germany, and with 200ms I'm being very generous), so that will total 300ms to get the packet from smartphone to the server.
Let's assume that it takes the same amount of time to have the server talking back to the car.
Since this should be a two way trip (for the car acknowledging that execution of the command) the total time to have your App receiving the confirmation should be:
2 * (300 (smartphone -> server) + 300 (server->car) ) = 1200ms =1.2s
And if you command let's say to flash the lights then should flash within 0.6s.

But what we are seeing here is an extra 10s which is protocol inefficiency (or call it security).

I'm seeing the same thing with my car (about 10s) to execute a command.

I've had it on a few cars. Only use it to lock/unlock if I leave me key in the house or something. It's not fast.

I agree with this. Since COVID I have not really used the feature at all.

I guess I'm used to things working quickly. Imagine if it took 10 seconds for the keyfob to unlock/lock the doors lol.
