Description

This is a test plan for bluez as used by Ubuntu Touch. It does not cover scenarios and/or test cases for bluez installed on the desktop.

NOTE: This only covers BlueZ 5.x and doesn't respect 4.x in any way.

Dependants/Clients

Test Plan

Test target device: Nexus 4, BQ Aquaris E4.5 Secondary/backup device: TBD

Initial set up:

  • Install latest image on phone
  • Install BlueZ from the silo PPA
  • Reboot the phone

Manual Tests

Kernel Bluetooth Management Layer tests

BlueZ comes with several utilities to test the in-kernel bluetooth management layer. Those are

  • bnep-tester
  • hci-tester
  • mgmt-tester
  • rfcomm-tester
  • userchan-tester

Each of them tests a different functionality part of the kernel bluetooth management layer. We're going to run all of them as part of this test plan.

As preparation for some of them we have to do the following:

  • Stop the bluetoothd daemon

$ sudo service bluetooth stop
  • Make sure bluetooth is turned off but rfkill not blocked.

$ sudo rfkill unblock bluetooth
$ sudo hciconfig hci0 down
  • Load VHCI kernel module

$ sudo insmod /lib/modules/hci_vhci.ko

Adapter

As first thing we need to verify the Bluetooth adapter was correctly initialized and is ready to be used. Check with

$ hciconfig

that an HCI interface is present (normally hci0). Output should be similar to this

phablet@ubuntu-phablet:~$ hciconfig
hci0:   Type: BR/EDR  Bus: UART
        BD Address: 4C:74:03:64:82:1F  ACL MTU: 1021:4  SCO MTU: 184:1
        DOWN 
        RX bytes:620 acl:0 sco:0 events:31 errors:0
        TX bytes:411 acl:0 sco:0 commands:31 errors:0

NOTE: The state of the interface should correspond to the Bluetooth indicator state in the UI. In the example above the interface is DOWN so the indicator should show disabled Bluetooth too.

As next step we verify the adapter is correctly connected the in-kernel management layer.

$ btmgmt info

The output should be similar to this

Index list with 1 item
hci0:   Primary controller
        addr 4C:74:03:64:82:1F version 6 manufacturer 70 class 0x000000
        supported settings: powered connectable fast-connectable discoverable bondable link-security ssp br/edr hs le advertising secure-conn debug-keys privacy static-addr 
        current settings: br/edr 
        name MTK MT6582 #1
        short name

If no controller is listed the test step should be considered as failed.

HCI

Run the HCI tester with

$ hci-tester

Afterwards we have to evaluate the output. Failed commands with status 0x1 (Unknown HCI command) can be ignored as those are then just not supported by the Bluetooth version the device supports

Management Interface

Run the management interface tester with

$ mgmt-tester

Afterwards we have to evaluate the output. All tests should pass.
