When using the rWire library with an ESP32 and B4R version 2.00 beta #1 I get this error. If I don't include the rWire library it compiles fine.

Multiple libraries were found for "WiFi.h"

This drove me crazy (in Arduino IDE). I had to delete any other WiFi.h file in other Arduino directories just to leave the right one referring to the used hardware. I used to delete to the recycle bin so I could restore it easily lateron. Since B4R uses Arduino system, that might be the same problem.

You can edit rWire.cpp and change the method code to:

  void WireSlave::Initialize(Byte Address, SubVoidArray NewDataSub) {
     instance = this;
     buffer.data = bufferData;
     buffer.length = 0;
     rcvBuffer.data = rcvBufferData;
     this->NewDataSub = NewDataSub;
#ifndef ESP32
     Wire.onReceive(receiveEvent);
     Wire.onRequest(requestEvent);
#endif
     Wire.begin(Address);
   }

This will allow you to use the ESP32 as a master.
