Research direction

Start at net/bluetooth/l2cap_core.c around line 6382 and reproduce the failure with the BlueZ study-guide sample, the listed Android devices, and btmon. Compare the Enhanced Credit Connection Request and subsequent kernel and bluetoothd logs to determine why service discovery stops. Done means the devices complete discovery and remain connected without the timeout or “Wrong link type (-22)” error.

Description

Describe the bug

A few Android devices are unable to successfully establish a bluetooth connection to the Raspberry Pi 4.
The devices connect, and after 5 seconds, it is disconnected with a timeout reason code 0x08.

> HCI Event: Disconnect Complete (0x05) plen 4
        Status: Success (0x00)
        Handle: 64
        Reason: Connection Timeout (0x08)
@ MGMT Event: Device Disconnected (0x000c) plen 8
        LE Address: 54:FA:15:75:50:1B (Resolvable)
        Reason: Connection timeout (0x01)
@ MGMT Event: Device Disconnected (0x000c) plen 8
        LE Address: 54:FA:15:75:50:1B (Resolvable)
        Reason: Connection timeout (0x01)

The following Android devices have shown this behavior:

  • Pixel Pro 6 - Android 12
  • Samsung Galaxy S10 - Android 10
  • Samsung Galaxy S21 Ultra

After connection, this message can be seen in the journal and dmesg:
raspberrypi kernel: Bluetooth: Wrong link type (-22)

The issue seems to be that during the discovery phase something goes wrong at the kernel level and the the device and raspi never completes the discovery phase. Bluez never receives the request for discovery and therefore the connection is closed due to timeout.

The log can be traced back to here: https://github.com/raspberrypi/linux/blob/2697f7403187bb2bb61cc716f33ee9f6cfb9af7c/net/bluetooth/l2cap_core.c#L6382

Steps to reproduce the behaviour

  • Download the Bluez study guide for Linux and transfer the code to the pi

  • Install python3-dbus sudo apt-get install python3-dbus

  • stop the bluetooth service sudo systemctl stop bluetooth

  • Verify the path for the bluetoothd ExecPath: $ grep Exec /lib/systemd/system/bluetooth.service

  • Run bluetooth service manually in debug and detached mode: sudo /usr/libexec/bluetooth/bluetoothd -d -n

  • Run the sample code sudo python server_advertisement.py

  • Launch nRF Connect app on one of these Android devices:

    • Pixel Pro 6 - Android 12, Samsung Galaxy S10 - Android 10, Samsung Galaxy S21 Ultra

  • Scan and connect to raspi

The client will connect, start discovering services and after 5 seconds on inactivity the device will be disconnected.
