Prevent Bluetooth from connection to several devices (multipoint)? - G4 Q&A, Help & Troubleshooting

Bluetooth on the LG G4 is driving me mad.. I am for example connected to my UE Megaboom and listing to radio. Then, my partner starts our car, which is just outside the house, with Bluetooth and it connects to my phone because I was the last one connected to it.
Now I have to manually disable that connection and if I'm lucky, media connects back to the UE again and then I can start my radio app to resume listening again.
Can this dreadful behaviour be disabled? I would be very happy if I just all together could disable auto connect in Bluetooth..

BT 338 on TOMTOM 5

Ok this might sound a bit dumb to you guys but I'm having a little situation here.
I got tomtom 5.1 and just got the glabalsat bt338 receiver.
I have paired the device with my xda as I have paired a nokia BT headset.
When I switch on the nokia headset and bluetooth, the pda and headset establish a connection automatically.
I would like to do the same for the bt338. As soon as the bluetooth is on, it should establish a connection.
I am not able to do this. I have to click on the bluetooth manager, double click the bt338 for it to establish the connection. Then I have to exit bt manager and turn on tom tom. Still tomtom does not detect the GPS receiver until I click on the GPS device settings and select OTHER BT RECEIVER and then select Blutooth receiver on COM5.
Only then does the GPS show any life.
I would like to know how to get the BT338 to work by just turning on TOMTOM.
It should authenticate and establish the connection on its own, and by the time its up, i should be able to input a destination.
Confusing? No?
easy there mate, give it time....once you have the BT338 paired with your handset, switch everything off.
then 1st switch on your BT338, then switch on your PDA...start up TomTom and leave it for at least 1 minute...it should switch on Bluetooth automatically and connect to the BT338, i had this issue and the 5.1 update solved it...let us know if successful.

Touch Pro 2, Xlink, and multiple headsets

Greetings all,
Just got the new TP2 through Verizon. Love the phone so far but decided to do away with Touch Flow and go back to old Windows interface.
Anyway, I have an XLink BT Gateway box at the house - routes cell phone through house phone landlines. Nice trick.
On my old Moto Q 9c, I could have my BT headset and XLink paired simultaneously. So, if the cell phone rang, I could answer the cell phone, BT headset, or house landline (via XLink).
With the TP2, I found that only one BT device can be active at a time. If the BT headset is turned on first, the XLink just blinks - indicating that it cannot connect to the TP2. If the XLink is activated first, the BT headset will not engage.
Suggestions?
Thanks

Bluetooth Issue - Connection lost

Hello,
I just have a Problem with my Phones.
Currently I use my G3 V10H and my Galaxy S3 (Android 4.3.1).
On Wednesday I connected my G3 to WLAN with Internet Access. Then I connected my S3 with my G3 and shared the Internet Connection with Bluetooth Teethering.
Everything works fine the whole day.
On Thursday I could not establish the bluetooth connection between the phones. I restartet both and it work. It was okay for me.
But today even the reboot does not help anything.
When the phones started I activate Bluetooth on every Phone. They dont have any paired devices. Then I search for bluetooth devices and try to pair the the other one.
The system shows me the pairing code and everything looks fine. Now I have the other device in the pairing list. But when I try to connect the device is working, then it shows "connected" and not a second later the connection is lost.
This problem is the same when I try to pair from my G3 or from the S3.
Any Ideas for that?

Automatic bluetooth connection with HFP

Hello, I have some problems with the bluetooth connection to my Seat Leon (2016). Pairing worked fine but once I return to my car only the A2DP profile gets connected. In the car menu media control is working correctly but the phone part is shown as disconnected. The bluetooth connection state in the phone settings shows "connected (no phone)" then.
To fix this I have to manually disconnect and reconnect bluetooth on the phone - afterwards everything is working as expected. This is very annoying though and I had no such issues with my previous Nexus 6P (stock 8.1).
Any suggestions? If there is no solution I try to fix this with tasker, however I'd clearly prefer a "native" solution.
Thanks in advance.
Seems like it's working with the app Bluetooth Auto Connect, will test it more intensively in the next days. But I'm still wondering why it's not working out of the box...

Frustrated with bluetooth problems with Oneplus 3

Hello,
I am frustrated with Oneplus 3 bluetooth issues. It often has trouble connecting to newer devices and connects sporadically. Right now it connects to my car radio and disconnects automatically after sometime. I can see in the car radio settings the bluetooth going from connected to paired to connected again. It also had a lot of trouble connecting to heart rate monitors. Is there a way to see bluetooth logs in a way that it can be easily understood what is going on with the bluetooth connections in lineage os. I understand that there is a bluetooth HCI snoop log but that is pretty difficult to understand.
