BTP audio and HID scenario tests

  • Article

The BTP audio and HID tests verify the ability of the local system to pair with both a HID and an audio device and use these two devices simultaneously.

Setting Up

Before using a Pmod device with the Traduci, check that the green power indicator, an optional yellow test LED, and 3 orange LEDs on the Traduci are on. Confirm that the SUT's Bluetooth radio is powered on and that the appropriate device(s) are correctly plugged in to the Traduci. Currently the RN52 device can only be plugged into JA. Similarly the Bluefruit device can only be plugged into JC. More detailed information on setting up can be found at BTP overview.

Two red LEDs on the BM-64-EVB should be on. One of the LEDs may eventually turn off. Confirm the switches, jumpers, and ports are configured for testing as described in the BM-64-EVB board overview.

Features and purchasing information for supported devices can be found at Supported BTP Hardware.

Supported devices

Running the Audio and HID Scenario Tests

Navigate to the folder where the BTP package was extracted. It's typically located under C:\BTP. In a folder named after the version of the package, you'll find the following scripts. Run either:

  • RunAudioHidScenarioTests.bat <audio device name> <hid device name> from an elevated command prompt or
  • RunAudioHidScenarioTests.ps1 <audio device name> <hid device name> from an elevated PowerShell console

Information on available device name parameters can be found Bluetooth Test Platform supported hardware.

You can also include the optional parameter -VerboseLogs at the end to get a more verbose output of inner operations of BTP.

As a test starts on the Traduci, the red LED next to the 12-pin adapter turns on when the command to power the Pmod device has been sent. This LED is turned off at the end of every test. If it is on at the start of the next test, due to the previous test failing, power it down and power it back on to return it to a known state. If the power cycle fails, the test fails due to the Pmod device being in an unknown state.

Capturing Logs

To capture the Bluetooth logs, follow the instructions for the busiotools for Windows Repo on GitHub.

To parse the Bluetooth logs, follow the instructions for the BTETLParse tool.

Known issues

  • Stress tests: Tests run in a tight loop using an LE device may cause pairing or unpairing to fail.
