I hear continuous "click" noises, it seems like the laptop is constantly connecting and disconnecting, it only stops when I disable Bluetooth.

main.conf changes:

# Enables D-Bus experimental interfaces
# Possible values: true or false
Experimental = true

ControllerMode = le

MinConnectionInterval=16

What's the Bluetooth version?

[haecker-felix]

The asha-support branch is 5.76

[barolo]

The asha-support branch is 5.76

I meant what's the supported BT version of your hardware.

[haecker-felix]

It's a Intel AX200 with BT 5.2, but given the asha-poc already worked finely I doubt it's a hardware limitation.

It's a Intel AX200 with BT 5.2, but given the asha-poc already worked finely I doubt it's a hardware limitation.

You're right, if asha-poc works that's not the issue.
Do you have SELinux enabled?

[haecker-felix]

selinux is disabled

Reading through the pcap file, I see it successfully retrieving the asha read-only-properties in packet 6783, but I don't ever see it establishing a connection. It also appears to be getting errors whenever it tries to read values from the device.

The embedded log messages also don't seem to match the current source code.

I suspect that the device has a bad gatt service cache. Can you try the following:

0. Compile and run the latest version of the asha-support branch.
1. Remove the device from your bluetooth configuration.
2. Use sudo btmon -w capture_file_name.snoop to begin capturing data.
3. Go through the bluetooth new-device dialog, for one hearing aid only.
4. run the simple-asha script
5. stop capturing data.
