After few seconds samsung id disconnected

from messages:
plasmashell[2230]: org.kde.bluez: PendingCall Error: “Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus sec
urity policy blocked the reply, the reply timeout expired, or the network connection was broken.”

Can someone tell me how to configure bluez to be seen as bluetooth speaker of bluetooth headphone for samsung TV?

Hi,
I am in tumbleweed and the connection only allows one device per connection.
So you have to disconnect the iphone first.
Under bluetooth-adapters uncheck powered, then apply the setting
and then check Powered again to power on, then apply setting.

In bluetooth-Devices click on samsung and connect.

In your samsung tv you have to allow your machine to connect.
You can go to the samsung tv settings and check if your linux machine is
allowed and listed in the device manager.
I am using Samsung 7 Series

Hope this help

As a followup to my post.
In my tv’s device manager’s list the linux machine is detected as phone
and configured to allow connection. It streams the audio to the other tv
connected to the linux machine as monitor and to the linux machine’s
audio speakers.

Regarding BT connectivity to one or more than one device…

First, people should know that often you don’t need to know the BT version of your devices. BT versions are generally backwards compatible with other devices (and in a backwards way can be considered forwards compatible) so bottom line is that practically any BT device can talk to another BT device no matter the BT version and when the devices were manufactured. Of course, whenever devices with different BT versions will only support the features of the lowest common denominator which will be the oldest BT version.

But,
BT 4.0 which is probably most common even today supports connecting to only one device and so much disconnect from one device to connect to another.
I think it was BT 4.2 which introduced the capability of a kind of “mesh connections” where a device could connect to, and relay data, and is approx 2+ years old.
Current version is BT 5.0 and at CES this year announced a “Next Generation” with ultra low power more than doubling battery life plus enhanced connections, devices with this version are supposed to start showing up Q3 or Q4 2020.
