Measure the current consumption
Set the approximate range of the ammeter to 0.2 mA and measure the current being consumed by the DUT.
5.6 SNIFF_500ms_Slave Mode
This section explains how to set the BCM4324/BCM4334 to SNIFF_500ms_Slave mode. Steps include the follow-
ing (Some of the steps apply to the DUT, and others apply to the reference board.):
■ Set the HCI Control Transport profile on the DUT.
■ Reset the DUT.
■ Set the Sleepmode parameters on the DUT.
■ Read and record the Bluetooth Device (BD) Address of the DUT.
■ Set the Write Scan Enable parameters on the DUT.
■ Set the Event Filter parameters on the DUT.
■ Create a connection from the reference board.
■ Set the Write Scan Enable parameters on the reference board.
■ Set the Write Link Policy Settings parameters on the DUT.
■ Set the Write Link Policy Settings parameters on the reference board.
■ Set the Sniff Mode parameters on the reference board.
This section concludes by specifying the approximate ammeter range setting for measuring the current being con-
sumed by the DUT.
Before you begin, set up and turn on the test equipment and launch Cypress BlueTool.
Set the HCI Control Transport profile for the DUT
1. Open a log window. On the View menu, click Log Window .
2. On the Transport menu, click HCI Control .
3. In HCI Control Window Transport:
■ Select UART .
■ In the top UART list, type the COM port of the PC to which the DUT is connected ( com4 ).
■ In the bottom UART list, select 115200 .
■ Select the CTS flow control check box, and then click OK .
Reset the DUT
1. In HCI Control: com4@115200, press the 3 key on the keyboard to select the Host Controller & Baseband
commands.
2. In the list of Host Controller & Baseband commands, double-click Reset .
Set the Sleepmode parameters on the DUT
1. While in HCI Control: com4@115200, press the 0 key on the keyboard to select the Vendor-specific
commands.
2. In the list of Vendor-specific commands, double-click Set_Sleepmode_Param .
3. In HCI Command: Set_Sleepmode_Param:
a. Make the following settings:
■ Sleep_Mode UART
■ Idle_Threshold_Host 0x0
■ Idle_Threshold_HC 0x0
■ BT_WAKE_Active_Mode Active High
