10.1.2 Antenna Selection

The CC3135 device is designed to also support antenna selection and is controlled from Image Creator. When enabled, there are 3 options possible options:

  • ANT 1: When selected, the GPIOs that are defined for antenna selection with set the RF path for antenna 1.
  • ANT 2: When selected, the GPIOs that are defined for antenna selection will set the RF path for antenna 2.
  • Autoselect: When selected, during a scan and prior to connecting to an AP, CC3135 device will determine the best RF path and select the appropriate antenna (12)(13). The result is the saved as port of the profile.

Figure 10-5 shows the implementation of a complete Bluetooth® low energy and WLAN coexistence network with the WLAN operating on either a 2.4- or a 5 GHz band with antenna selection. The SOP lines control the 5 GHz switch. The Coex switch is controlled by a GPIO signal from the BLE device and a GPIO signal from the CC3135 device. The Antenna switch is controlled by 2 GPIO lines from the CC3135 device.

Figure 10-6 shows the antenna selection implementation for Wi-Fi®, with BLE operating on it's own antenna. The SOP lines control the 5 GHz switch. Note in this implementation no Coex switch is required and only a single GPIO from the BLE device to the CC3135 device is required. The Antenna switch is controlled by 2 GPIO lines from the CC3135 device.

12. When selecting Autoselect via the API, a reset is required in order for the CC3135 device to determine the best antenna for use.
