Bluetooth disconnects when buffering.

[HIV]

Hello guys!

I recently put Bluetooth into an old boombox from the eighties. It works great, except with my galaxy s4.
Bluetooth keeps on disconnecting and rapidly reconnecting whenever I try to stream via Google play music or YouTube for example. It works fine with local files. As I have a poor Internet connection, music takes some time to start streaming, that's when it disconnects. So it is clearly related to the time it takes before a song starts playing. But pausing a song works fine, and it stays connected when nothing is playing for hours.
It works fine on my tablet though, even when music has to buffer 30+ seconds before it starts playing.

It must be related to my phone, it has the original Samsung lollipop firmware but it is rooted and has xposed installed (of course).
A factory reset is not an option, I have done way too many tweaks for that.

Has anyone been having this problem?
Is it possible to install a newer/different Bluetooth firmware?
Or does anyone know an app/ xposed module targeting this problem?

Thank you in advance,
VIH

Rooting has no effect on apps that don't request root permission. And unless you're running an Xposed Bluetooth module, that should have no effect on Bluetooth either.

But the difference between the "Bluetooth" of years ago and even the Bluetooth in an S4 is almost astounding. Updating the Bluetooth adapter in the boombox might help. (Bluetooth has nothing to do with wifi, so having slow wifi should have nothing to do with Bluetooth.)

I don't think my initial post was clear, I do of course understand the basics of Bluetooth, WiFi, root and xposed.

The issue is that the phone disconnects the Bluetooth whenever a video/song buffers for more than 10-20 seconds.
And as I said, the boombox works fine with all other devices I use (tablets, laptops, other phones). The Bluetooth I build into the boombox is quite up to date too (4.0).

I'm just looking for an app/xposed module that prevents the phone for disconnecting a Bluetooth device on it's own.
