Conflict Between Wifi101.h and SoftwareSerial.h

[mjmoore10]

If I try to use wifi101.h and softwareserial.h in the same sketch, I get the error messages below from the IDE. I'm a beginner, so I may well be wrong, but it looks to me like both header files define either functions or variables with the same names, which causes the conflict. If there's really a bug, I hope this report is helpful. If I'm just ignorant and this is an avoidable problem, I'd be grateful for any guidance.

Arduino: 1.6.7 (Windows 10), Board: "Arduino/Genuino Mega or Mega 2560, ATmega2560 (Mega 2560)"

Hi @mjmoore10,
thanks for spotting this bug!
In the meantime, if you only need to use a Mega, you can open libraries\WiFi101\bsp\source\nm_bsp_arduino_avr with a text editor end remove lines

#if defined(PCINT0_vect)
ISR(PCINT0_vect)
{
    if (!rx_pin_read() && gpfIsr)
    {
        gpfIsr();
    }
}
#endif

#if defined(PCINT1_vect)
ISR(PCINT1_vect, ISR_ALIASOF(PCINT0_vect));
#endif

#if defined(PCINT2_vect)
ISR(PCINT2_vect, ISR_ALIASOF(PCINT0_vect));
#endif

#if defined(PCINT3_vect)
ISR(PCINT3_vect, ISR_ALIASOF(PCINT0_vect));
#endif

This code is UNO specific and shouldn't be compiled for Mega.

I'm delighted to have helped in some small way. And thank you very much for
the workaround!
