Description

Test Hands Free Profile (HFP) BlueZ feature.

Resources

  • A Bluetooth adapter
  • A Bluetooth-enabled phone with a SIM card and a data plan. (https://www.apertis.org/reference_hardware/extras/)

Pre Conditions

  1. From a PC, download and unpack the test data tarball from the gitlab test repository:
    2. $ wget https://gitlab.apertis.org/tests/bluez-phone/-/archive/apertis/v2022/bluez-phone.tar.gz
    $ tar -xvf bluez-phone.tar.gz
  2. Copy the bluez-phone-* folder to the target device:
    3. $ DUT_IP=<device-ip>
    $ scp -r bluez-phone-* user@$DUT_IP:
  3. Log into the target device:
    4. $ ssh user@$DUT_IP
  4. After log into the DUT, enter the test directory
    5. $ cd bluez-phone-*
  5. Note that the tarball may change depending on the release/branch being tested, please make sure to download the correct tarball for the release in question.
  6. Please note that connman disables bluetooth by default on a fresh image.
  7. Enable device:
    8. $ connmanctl enable bluetooth
  8. When running the test on SabreLite boards using the headphone jack to check the audio output, the audio manager needs to be configured to route it accordingly as it defaults to the HDMI output:
    9. $ pactl set-default-sink alsa_output.platform-sound.stereo-fallback
    $ pactl set-sink-port alsa_output.platform-sound.stereo-fallback analog-output-headphones
  9. After reboot ensure that headphones will not be muted:
    10. $ pactl set-sink-mute alsa_output.platform-sound.stereo-fallback false

Execution Steps

  1. The phone must be in discoverable mode for starting this test. Look for the phone in this list, and save the BT address. It will be used while running the test.
  2. Execute the test suite inside an environment with dbus:
    3. $ ./bluez-hfp.sh
  3. There are some options:

    4. -a select which device you want to pair with (specify the address)

    -s skip pairing because the device is already paired. -a must be present when using this.

    -x enables test debugging (only useful if a test fails)

  4. Once the test begins, after Apertis finishes pairing with the phone, you must initiate pairing from the phone and do the pairing again as part of the test. You may need to unpair Apertis from within the phone first. The test will display the following message when that is required:

    5. Start a pairing from the phone! was it successful (y/n).

  5. After you've initiated the pairing from the phone, the test will continue.
  6. If the pairing fails from the test, try to do the pairing separately, and then run the test using './bluez_hfp.sh -a <phone addr> -s'. To do a separate pairing: unpair the phone, and run 'bluetoothctl'. Then, in bluetoothctl prompt, issue the following commands in order: 'remove <phone addr>', 'discoverable on', 'agent off', 'agent NoInputNoOutput', 'default-agent'. The either 'pairable on' to pair from phone, or 'pair <phone addr>' to issue a pairing to the phone. '<phone addr>' is the phone address of the form 'a1:b2:c3:d4:e5:f6'.
  7. The next step is to initiate a call from the phone. This can be done by entering the contact. The test will display the following message when that is required:

    8. Did you recieved the call (y/n)

  8. After you’ve recieved the call in other phone number continue.
  9. The next step is to call from other phone to the phone connected to the bluetooth adapter. The test will display the following message when that is required:

    10. Did you hear the call (y/n):

  10. After you’ve heard the call from other phone number the test case is passed

Expected

If PASSED is displayed, all of the test have passed. The output should be similar to that:

 PASSED

If FAILED is displayed, bluez-hfp test has failed and the test sequence is interrupted.

Notes

  • Errors most frequently occurs at pairing. This can be used to circumvent pairing problems, though this does not mean the test is a full pass, as the pairing is part of the test:

    • cd ~/bluez-phone-master

    armhf/bin/pair_two hci0 <bt address of the phone>

    ./bluez-hfp.sh -a <address of the phone> -s
