4.6 Coexistence (Planned)

CC2340 series offer a coexistence feature to avoid collisions between Bluetooth Low Energy and WIFI devices. A PTA (Packet Traffic Arbitration) interface is used to decide which device is allowed to use the frequency band. The Coexistence feature requires the WIFI device to run in a Master role. In this case the Bluetooth LE device has to request access to use the antenna. The WIFI chip provides this by Granting access. The 2 Mbps transfer mode implemented in CC2340 offers lower radio communication time and thus is designed for Coexistence use. A detailed description of the implementation of the Coexistence scheme can be found in our SimpleLink WLAN Access Point Application Note.

Note: Please note that the Coexistence feature is not published within our recent SDK. This feature is included with one of our future releases.
