BlueTool is a proprietary Cypress software tool for exercising, testing, scripting, debugging, and programming
devices that use Cypress Bluetooth chips. BlueTool runs on a standard PC running Microsoft Windows (either
Windows XP or Windows 7). BlueTool interfaces with the Cypress Bluetooth chips at the HCI protocol layer.

Firmware/configuration files and minidriver files for the BCM4324/BCM4334 are available via Cypress’s Customer
Support Portal (see

IoT Resources on page 2

Test Equipment Setup

Connect the test equipment as shown in

.

■

Use USB/RS-232 (straight-through) cables to connect the DUT to the PC.

■

Use USB/RS-232 (straight-through) cables to connect the reference board to the PC.

■

Using appropriate lead wires, connect the attenuator to the RF port of both the DUT and reference board.

■

Using appropriate lead wires, connect the ammeter to VBAT on the DUT.

Figure 1. Test Equipment Setup

The range setting on the ammeter varies depending on the test mode. The ammeter range setting is specified in

the procedure for that test mode.

Downloading the Minidriver and Configuration File

This section provides instructions for downloading the minidriver and configuration file to the DUT and reference

board. You must download the minidriver and configuration file before you begin setting the various modes. Steps

for downloading the minidriver and configuration file include the following and apply to both the DUT and reference

board:

■

Set the HCI Control Transport profile.

■

Reset the DUT/reference board.

■

Download the minidriver.

■

Download the configuration file.

Before you begin, set up and turn on the test equipment and launch Cypress BlueTool.
