PurePath Wireless Configurator
|Part Number||Buy from Texas Instruments or Third Party||Alert Me||Status||Current Version||Version Date|
CC85XX devices are delivered unprogrammed from TI and need to be programmed with firmware to run in a customer application. Different firmware is needed depending parameters such as network and application role (audio transmitter, audio receiver etc), how audio is streamed, and application circuit design.
PurePath Wireless Configurator (PPWC) is a graphical PC tool used with CC85XX devices, and no extra 3rd party tool is needed. PPWC works on precompiled image files. Based on input from the user, PPWC will patch these to generate a downloadable firmware image. The designer will then be able to program the CC85XX device directly from PPWC through the CC Debugger tool (included in CC85XXDK) or output it to an Intel HEX-file (for production programming).
Firmware 1.0.3 and later firmware versions are not compatible with firmware version 1.0.2 and earlier. Firmware 1.0.3 introduces improved RF packet integrity checking, which improves the robustness of the PurePath Wireless platform significantly. Refer to the PurePath Wireless Configurator change log for further details. Contact TI support for access to older firmware.
