Automate protocol and
profile interoperability testing.

The Bluetooth® Profile Tuning Suite (PTS) is testing software that automates compliance testing to the specified functional requirements of Bluetooth Host Parts and specifications that reside above the Host Controller Interface (HCI). The vision of the product is to provide complete and validated test coverage, of all specified functional requirements in scope, to the Bluetooth development and testing community.

Profile Tuning Suite (PTS)

Starting with PTS v8.0.0, you must select and connect to one of the available radio modules before executing PTS test cases (See PTS Help, Section ‘Connecting a Dongle’).

In addition, updates to PTS Automation API clients will be necessary (See corresponding PTS Sample Code and Documentation).  

To enable the Extended Advertising feature, PTS 8.0.0 introduced support for a new Bluetooth Low Energy radio module (Laird Connectivity, part number 451-00004).  

Starting with PTS v8.0.1, the protocol viewer is no longer included in the PTS installation package. The protocol viewer can be downloaded separately from the PTS installer (See PTS/PV Download Page).
Note: Close PTS before installing the protocol viewer.

Pricing and Support:

Profile Tuning Suite (PTS) and PTS Firmware Upgrade Software are free for all registered SIG members and are available for download here.

PTS testing equipment (dongle) is required to enable testing of Bluetooth Specifications and your physical device. Dual-mode dongles can be purchased here. The new LE-only radio module hardware can be obtained from authorized distributors (See PTS Help, Section ‘Purchasing the New LE Dongle’) and will require specialized firmware that is now available. Note: Laird Connectivity (LE-only) dongle does not come with PTS firmware pre-installed. To install PTS firmware, please download the ‘PTS Firmware Upgrade Software’ from the official Bluetooth download page and follow the directions in the dialog window.

The legacy BR/EDR/LE dongle can test BR/EDR and Low Energy features of Bluetooth Technology. Use it with PTS to efficiently conduct all your core host, protocol, and profile qualifications testing (requires PTSv7.0.1 or greater). The dongle also supports Bluetooth mesh networking (Two dongles are required to test with a mesh network).

For all support questions, please submit a PTS ticket here.

PTS Firmware Upgrade Software

PTS Firmware Upgrade Software v1.0.0 will enable appropriate dongle firmware upgrades as they are available for a given dongle version. 

Note: Laird Connectivity (LE-only) dongle does not come with PTS firmware pre-installed. To install PTS firmware, you will need to download the “PTS Firmware Upgrade Software” and complete the installation process.
