Bluetooth - Multiple user not supported

Dmc2008

Hi, my wife do drive my car sometimes and therefore need to connect to my Dudu7 HU for calls and Spotify. However I do notice we need to unpair and repair our phones to the head unit before we can use. The apple CarPlay won’t connect also. Could anyone advise it there any workaround or put into the next software updates? Most of the basic head unit in the market are able to switch connection or auto detect different user. I hope Dudu7 can improve on this. Thanks

As long as you two aren't both in the car at the same time, you can both connect to the phone used for driving normally.

Not automatically.
Dudu, like all FYT units, connects automatically to the last paired phone.
It will not pair automatically to the "second" phone if the "first" phone is not available.
This is already an issue for many years (since 2015/2016) and has also been mentioned many times in the Telegram group.
It will only automatically connect to the last paired phone.

It could be a very simple change to search for available phones and pair automatically to the last paired phone, and if not available, pair to another defined phone if it is available.
I guess this is a change for FYT, as it has been since 2015/2016.

Hi, I currently need to manually reconnect via the Bluetooth tab instead of having it connect automatically, especially when both phones are not in the car at the same time.

It would be great if you could implement a feature that allows phones to connect in a set sequence. For example, my previous Pioneer head unit allowed us to assign connection priorities — if the first phone wasn’t detected, it would automatically connect to the next one on the list, supporting up to four paired phones.

I hope you can look into adding this function, as having to manually reconnect every time takes about 5–10 minutes and is quite inconvenient for such an advanced head unit.

Thanks!

I realize now that we are already waiting 9 or 10 years for this change. Absolutely ridiculous!!

Nowadays I think every android supports up to several connected bluetooth devices, regardless of the OS. Why can't the DUDU OS do this, what are the limitations?
Why should the OBD connect via the Android OS and the phones via the DUDU OS, in my opinion this is ridiculous.
Hopefully in the next updates the errors will be fixed, which are quite a lot for this type of device (like money, quite cheaper alternatives handle the connectivity better)

Dmc2008

The basic head-unit with 20 years ago technology already provides such function. It’s about time Dudu should look into this !!

Alternatives to their devices offer this, which are 3-4 times cheaper. I thought that by purchasing a device for nearly $1000 (after VAT and Customs) everything would work, even better than the original media, but it turned out to work worse than a 2 times cheaper alternative.

10 years old devices even offer Guest mode, so two phones are connected for audio simultaneously (not for calls)...
Now, since dudu7 uses additional own BT chip for calls and audio, leaving default BT alone, maybe two phones pairing would be feasible. At least Dudu is describing their BT module as "top notch, top end" (just ignore Qualcomm who say this chip is entry level chip - I'm being sarcastic here)...
@benzol you're not the only one. More and more I crack this unit electronically and more I use it, I so regret paying double for a buggy software on a medium range headunit that could be bought otherwise for 200USD.

Mikescotland I basically wanted to return mine but my losses would be big, Aliexpress could only refund me 420-440 euros which is far from what I paid.
I wouldn't recommend it to anyone to buy it for this price.

Dmc2008

Totally agree with Mikescotland. The Dudu7 head unit has quite a few limitations — you can’t even adjust the subwoofer gain or phase when using an external subwoofer. The only way to achieve full control with an external amplifier is by adding a separate sound processor.

It has been verified that the current logic prioritizes the last connected device. Future plans include implementing dual-device Bluetooth connectivity for DDU7.
Regarding custom priority settings, discussions are still ongoing.

DUDU-Meng Future plans include implementing dual-device Bluetooth connectivity for DDU7.

DUDU-Meng The Bluetooth chip in DUDU4/5/6 does not support multi-device connections; this is a hardware limitation.
While Bluetooth connection priority could be considered, these features cannot be implemented in the short term. Bluetooth involves numerous areas, including inter-device screen mirroring and authorization protocols, requiring extensive testing.

Thanks for the feedback, but actually we are talking about two different functionalities here.
Your first answer is about multi-device connections. This is when the Bluetooth chip allows for the connection of 2 phones at once, where one can take control and the other can only be used for calling. This is indeed in newer BT chips (since 6-7 years?). That is great functionality, and I would like that to be implemented, but that is not what this topic was first about (and not my personal priority).

The topic was about the fact that the dudu units only automatically connect to the last paired phone, while multiple phones are defined. If I get in some other car that has "Mengs iphone" and "Harry's S22 Ultra" defined, it automatically connects to the phone that is in the car (or that is first in the car in case of both phones). That is simple scanning for earlier defined devices and connecting to the first one it finds after reboot/deep sleep.
Any dudu "could" do that at this moment.You could do it programmatically after reboot/deep sleep.

And you mention "While Bluetooth connection priority could be considered".
As such it is not about priority. as first step It is simply connecting automatically to the phone that is in the car at that moment: my phone, my wife's phone or my sons phone.
With priority, do you mean that you can give a priority sorting in defined phones?
In case of 3 phones in the car, or number 1 and number 3. It would first scan for the "priority phone 1", then for "priority phone 2" phone and then for "priority phone 3". That would be great functionality, both for single-mode connectivity as well as multi-mode connectivity.
Is that what you mean?

Dmc2008

Thanks @DUDU-Meng. Hope we can get an update soon!

Do you plan to make the feature also for DUDU 6(7862)?
It is really annoying to go to the menus and switching bluetooth device every time different person sits in the car.

Regarding the last issue you raised:
The priority order is 1, 2, 3. It will first scan 1. If it's out of range, it will connect to 2.
If 2 is also out of range, it will connect to 3.
However, this solution was rejected by FYT, and I'm still in discussions with them.

Thanks, that would be great functionality. Please push FYT to do this 🙂

Like mentioned: Already in 2016, we as users on the XDA forum and the Joying forum, tried pushing Joying to push FYT to implement this. It is ridiculous that FYT never picked up on this. (Not Dudu's fault, I know).

I really want this as well. And by this I mean - find any phone previously paired and available now, connect to it.
Me and my wife share the car. So if she uses it in the morning and connects, when I use the car in the evening it does not connect with my phone automatically. Sometimes it does not even connect when I select my phone from the dudu7 settings. Infact I have to pull out my phone, goto bluetooth settings and connect from there for it to work which is very annoying.
You can go fancy with setting priority and all, but at bare minimum just loop through the paired phones and try to connect anyone if the last paired phone is not available.

Dmc2008

If I had known about this issue before purchasing the Dudu7, I probably wouldn’t have bought this head unit. I guess now we just have to put up with it and wait for FYT. By the way, is there any way to contact FYT directly?
