(1)
The CC3135MOD modules are compatible with TI BLE modules using an external RF switch.
(2)
A single antenna configuration is possible using the CC3x35 devices.
(3)
For dual antenna configuration antenna placement must be such that isolation between the BLE and WLAN ports is at least 20 dB.
5.12 BLE and WLAN Coexistence Requirements
For proper BLE and WLAN 2.4 GHz radio coexistence, the following requirements must be met.
