SW 2 Bluetooth Problem?

Hi,
I've got yesterday sw2. It is really cool, but sometimes i have problem with bluetooth. Sw2 seems to be connected with phone, but when i start some app, it is loading, but this app don't start. I must restart my watch and then everything works fine, but then when i don't use it for a while it didn't want start against. I am using nexus 5 with custom rom. Where can be a problem?

I am having the same problem. Also a nexus 5 with custom rom. Maybe this is a nexus issue?
Which kernel are you running on the phone.

I am using latest Droidkang rom with stock cm kernel.

Some times I will clear phone's RAM to temporarily resolve this problem.

Any ideas anyone? I have the same problem on stock 4.3 on HTC One Max. It drives me nuts ^^

Stock Nexus 5 has no such issue so I'd start with the kernel /ROM bluetooth compatability. Certain apps seem to lose their state occasionally I've noticed. They generally just need to be closed and reopened though. No reboot has been necessary.

Difficulty with MediaTek devices
I have a Wiko Stairway, which is built on MediaTek platform. Pairing is difficult but possible. I don't know whose fault it is, MediaTek or Sony or both?
Still I find it awkard that I have to install 10MB of Sony software just to establish a faulty connection.
My workaround:
Pair the devices without installing the Smart Connect suite
Install Smart Connect and restart watch
Start Smart Connect and wait a while. It should now find the watch and prompt for installing the add-on
Turn bluetooth off and on on both devices
It should now work
Problem is that every now and then the connection is dropped and you may have to toggle bluetooth on either watch or phone or both. Even sometimes a restart is required.

A work around might be to see if force closing the app 'bluetooth share' temporary resolves the issue. If that's the case you could set up a tasker task to kill bluetooth share every 8 hours or so. You might need a plug-in to properly kill bluetooth share with tasker.

Android Auto

Hi,
Did somebody try to use an android auto function? My car (Peugeot 308SW 2018) and the phone not connecting with latest (8.1.0) android version. I tried to enable an USB debugging (as workaround recommendation), but nothing changed...
Have you other idea or working solution?
thx!

Yes, it works perfectly in my mid 2017 Kia Cee'd SW. Check if you have android auto enabled(i have the option to disable it and the apple car play). Also, the usb cable is working properly when connecting to a pc?

At the car side is enabled, at phone side i didnt found any additional options...
The best result was the android auto icon at phone appears and disappears continously with 2-3 different cables.
Is it possible the car head unit firmware not compatible with N7P latest SW version?

Doubt it. The car is from this year, it seems unlikely(to me) that the firmware wasn't up to date.
Stupid question, you have the android auto app installed on the phone right? Android has a Car Mode but to use android auto you need to install the app 1st(https://play.google.com/store/apps/details?id=com.google.android.projection.gearhead&hl=en). If the link says that you have no compatible device, download the latest version from here(https://www.apkmirror.com/apk/google-inc/android-auto/)
For almost a year I thought my head-unit wasn't up to date as the android auto would freeze, the app would say that the head-unit wasn't up to date, waze would display random artefacts, etc.
Now with the N7p it is butter smooth, no funky stuff and way more responsive that when I was trying to use it with my Redmi 4 Prime(same cable but with a micro-b to usb c adapter)...

No issues with AA in Seat Ateca 2018.
Everything works like a charm.
For phonecalls, you need to select default sim first, otherwise the call hangs on a sim selection prompt on the phone.

I write to nokia support and they send:
- clear the bluetooth cache
- do a soft reset
after this steps working fine...

what is Bluetooth cache?

You found here, how to clear: http://support.hereplus.me/hc/en-us/articles/115003497328-Clearing-your-Bluetooth-Cache-Android-/

Do you install android auto app on your smartphone ? some lands doesn't have android auto on the play store, so you need to download manually on apk mirror web site (arm64 version)
A good quality cable is also needed.

I'm having similar issues.
This phone won't work in both my VW cars.
If I clear all settings it works fine.
I get to my destination, unplug and then when I head out on my next trip it doesn't. Just a blank screen on the head unit and the phone has the green screen saying launch Android Auto on the head unit.
Tried the BT cache clearing as above. Will try a factory reset of the phone shortly too otherwise wait for pie and if still no go then sell the phone which I will miss
Though can't work without Android Auto now

It is definitely problem with Nokia 7 plus. In my car it connect and after few minutes black screen and solution is only disconnect and connect again.

I've found the bluetooth with my N7P poor anyway. This is my second one and the same as the first.
All HMD will do is send you a list of the bluetooth protocols they support.
So you may need to change your car ?

My 7+ works perfectly now.
Enable USB debugging and disable the extreme power saving settings.

Multiple Bluetooth devices at once?

I'm currently on a ROM based on 8.1 that doesn't appear to support multiple Bluetooth devices (Havoc ROM) For instance, I'm looking to connect my Gear S3 and car Bluetooth at the same time and it simply does not let me.
Rather than flashing back to stock to find out and being forced to redownload everything, can someone tell me if the latest release for OP6's stock ROM supports multiple devices being connected at the same time?
I know Android P will cure this, but I am curious if it can be done now.
Thank you guys! Loving this phone so far

no

[PAIR] Dualshock 4 over bluetooth

I tried to connect the DualShock 4 to my Oneplus 6 via bluetooth but after 30 seconds working properly, an imput lag appears and the controller becomes unusable.
I have searched the network and the error is common in many devices, but they all solve it with an application called Bluetooth Auto Connect.
But in OP6 it does not work, neither version 4.2.2 nor 4.5.4, none of the options that you select inside the application solves the problem.
Is there any way to correct it?
I have Android 9.0.2 rooted with Magisk + XXX 4.0 module.
thanks

What rom are you using? For me it is working on Omni except the x button... I tried changing the keylayout and everything but the x is not working. on my Nexus 5 it is working properly.

ow boy, I had this problem with the input lag on my nvidia shield device. I also used the bluetooth auto connect app to evade input lagg.
Interrestingly enough, I found out that a dualshock v1 works without problems and reduces input lag, but if I used a dualschock v2 the input lag kept coming back, therefore my sollution was to use a dual shock v1 version.

I just bought an iPega 9099 bluetooth gamepad and i must say that i am impressed, no latency at all, you can fin it for 25$ on amazon or aliexpress or gearbest, really happy with my purchase

hmm interesting, never tested on newer android systems like nougat or pie, only used on my shield tablet which has 7.0
on nougat the v1 was the only sullotion, but to be honest it is unacceptable to have input lagg on anny android system.
I hope there is a way to fix this !

Bluetooth auto-reconnect issues

I have OP7 PRO running android 10 and stock Oxygen OS (not root).
When I pair my device to my car bluetooth set everything works fine, but once the connection is lost it will not auto-reconnect the next time i'm in my car.
Moreover, in order to connect again i need to do the pairing again (not just select the device from the existing devices list).
I saw tons of threads online about this with no solution, some mentioned they think it's an issue with android OS and not the phone itself (this is supported by the fact that my wife just got a new Xiaomi and have the exact same problem).
Does it make sense that this is a global Android issue and has no fix for such a long time? did anyone experience it and managed to fix it?

I would guess at an issue with the car Bluetooth. May be theres a firmware update for that ?

That was my first thought, but it seems that the issue is on the device side as i can see that after connecting the device doesn't appear in the previously connected devices list.
As if the phone forgets it for some reason.

I've had occasional problems too. I'm using Launcher 10. Just last week, I turned on my wifi before starting my car as usual. It connected, then disconnected 2 times and then was stable. There's been times where I'll restart my car to fix it. It's irritating but who knows what can be done about it.

I have a rooted stock op7pro and I have a Samsung active2 watch that randomly disconnects and reconnects once or twice an hour. I have battery set to all Samsung apps on my phone to not optimize battery usage and I have no idea why it does this.

I have understood that it's also possible that it depend on the order in wich you connect.
You should first have to connect the car to the phone instead of the phone to the car.
Iow have the car lookup the phone

Yes, i head a lot about people with flaky connection but i hope that was the situation, for me it won't reconnet 100% of the times.
Changing the order of connections didn't work.
