RF switching on STM32L4XX

Hi 

I want to communicate between two STM32L4 MCU, and interfaced RF on to UARTs.

UART1 -- BLE

UART2 -- XBEE

I want to make a transparent, i mean when there is NO BLE there should be a switch to XBee and the other MCU has to be altered to make a seam less communication. When there is enough RSSI for BLE, XBEE and BLE both has to communicate simultaneously in run time.

 

My queries : 

a. Does the above scenario can happen in run time?

b. If i make a switch in run time will be there any effect on RFs.

 

I would like to know a better approach to make a RF switch at run time.

 

Thanks

Phani
