To change this functionality the CC85xx must be re-programmed. Figure 3 shows how to connect

the CC debugger to the CC85xx Headset board, which is used to program the CC85xx. The

CC85xx Headset board must be powered either with the battery or the USB cable, in order for the

CC Debugger to recognize the CC85xx. Further it’s important to place the programming connector

so that the red wire (pin 1) is oriented towards the USB connector as shown in the Figure 3. For

more details about the programming connector see section 6.6. If the board is powered and the CC

Debugger is connected correctly, pressing the reset button on the CC Debugger should make the

LED on the CC Debugger turn green. If so, the CC debugger is ready to download firmware

images from the PurePath Wireless Configurator.

The PurePath Wireless Configurator is used to configure the functionality of the CC85xx, and it can

be downloaded from the PurePath Wireless Configurator product page [4]. A screen shot of the

PurePath Wireless Configurator is shown in Figure 4.
