SWRS227C March 2020 – December 2024 CC3130
PRODUCTION DATA
The CC3130 device is designed to also support antenna selection and is controlled by Image Creator. When enabled, there are three options possible options:
Figure 9-3 shows the implementation of a complete Bluetooth® low energy and WLAN coexistence network with WLAN and antenna selection. The Coex switch is controlled by a GPIO signal from the BLE device and a GPIO signal from the CC3130 device. The antenna switch is controlled by two GPIO lines from the CC3130 device.
Figure 9-4 shows the antenna selection implementation for Wi-Fi, with BLE operating on its own antenna. Note in this implementation no Coex switch is required and only a single GPIO from the BLE device to the CC3130 device is required. The antenna switch is controlled by two GPIO lines from the CC3130 device.
