Antenna Design

The reference designs we have on the web has a 50 ohm output, what do you define as "a common 2.4GHz Antenna"? If you mean a wipe antenna, this has 50 ohm and can be used directly. 

I want to use CC3135 and CC2541 by using a single 2.4GHz antenna
Do you have any General Instructions or Application Note or User Guide which explains how to implement the COEX?

Hello User,

There is no specific coex feature on the CC2541 other than to output the signals from the RF Core to GPIO pins, please refer to section 

7.9 Radio Test Output Signals in the device users guide:

The CC26x2 device has Coex features. Please refer to the training:

Thank you for your answer

By "a common 2.4GHz Antenna" I mean one antenna being used by both CC3135 ( a WiFi Controller ) and CC2541 ( a BLE Controller )

If you do not have a reference design which uses these two parts, Can you please suggest me any other WiFi Controller + BLE Controller combination which uses Coexistence?

Let me explain why I want Coexistence Solution

I'm developing a module for IOT, which needs to connect to Internet through WiFi Controller (CC3135)
I'm adding BLE to the Module, just for the end user to provide the module with the WiFi SSID and Password Information

If you know of any alternative solution, where the end user can tell my module which WiFi SSID and Password to use, I'd be happy to implement

Hi 

I m looking forward the answer
