Android Bluetooth device stuck in connect/disconnect loop with Linux Bluez Peripheral


For a BLE project I have been working on, I have created a smartphone application which serves as central, and a program in Linux, that serves as peripheral. After manually disconnecting via the phone, the program works as intended. But after disconnecting via the peripheral, the connection gets stuck in connect/disconnect loop.

I'm using "JustWorks" in bluetooth, which doesn't require any bonding/pairing.

The smartphone application is made in Flutter, and uses the flutter_reactive_ble library from Hue. The Linux program is written in Python, and uses the Bluezero package, but for disconnecting, I'm using:

subprocess.run("bluetoothctl -- disconnect", shell=True)

The terminal that is running the peripheral looks like this:

Attempting to disconnect from 58:93:C0:B5:9B:D7
Successful disconnected
[CHG] Device 58:93:C0:B5:9B:D7 Connected: no
Attempting to disconnect from 58:93:C0:B5:9B:D7
Successful disconnected
Attempting to disconnect from 58:93:C0:B5:9B:D7
Successful disconnected

The bluetoothctl terminal looks like this:

[CHG] Device 6E:4C:38:CB:4D:A9 Connected: no
[CHG] Device 6E:4C:38:CB:4D:A9 Connected: yes
[CHG] Device 6E:4C:38:CB:4D:A9 Connected: no
[CHG] Device 6E:4C:38:CB:4D:A9 Connected: yes
[CHG] Device 6E:4C:38:CB:4D:A9 Connected: no
[CHG] Device 6E:4C:38:CB:4D:A9 Connected: yes

This is the btmon output: From start to end: Received data -> disconnected from peripheral -> stuck in connect/disconnect loop.

For this project, I would like the peripheral to be able to disconnect, without getting stuck in the connect/disconnect loop.

Attempting to manually disconnect via the console in the bluetoothctl menu returns the same results.

It doesn't seem that the error is in my application. Debug statements proof that the connect method doesn't get called.

Does anyone have any suggestions/solutions for this problem?

Edit: It seems like this was an issue with Android, which got fixed in a newer version.
