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.
