(1) When selecting Autoselect via the API, a reset is required in order for the CC3135MOD device to determine the best antenna for use.
(2) Refer to the Uniflash with Image Creator User Guidefor more information.
Figure 7-1 shows the dual antenna 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. Note in this
implementation no Coex switch is required and only a single GPIO from the BLE device to the CC3135
device is required.

7.1.2 Antenna Selection
The CC3135MOD 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, CC3135MOD device will
determine the best RF path and select the appropriate antenna
