PRODUCTION DATA
The CC3230x device is designed to support BLE/2.4 GHz radio coexistence. Because WLAN is inherently more tolerant to time-domain disturbances, the coexistence mechanism gives priority to the Bluetooth® low energy entity over the WLAN.
The following coexistence modes can be configured by the user:
Figure 10-1 shows the single antenna implementation of a complete Bluetooth® low energy and WLAN coexistence network. The Coex switch is controlled by a GPIO signal from the BLE device and a GPIO signal from the CC3230x device.
Figure 10-2 shows the dual antenna implementation of a complete Bluetooth low energy and WLAN coexistence network. Note in this implementation no Coex switch is required and only a single GPIO from the BLE device to the CC3230x device is required.
