Which SoftwareSerial is intended to be used?

[mcsarge]

I cannot compile this code because it is asking for SoftwareSerial, and I do not know which one you have chosen to use. Or should I set the following flag: MT_SOFTWARESERIAL_SUPPORTED to turn it off, since I am on an ESP32?

[mcsarge]

Here is what I did to make it work: in mt_internals.h:

ifndef MT_INTERNALS_H

define MT_INTERNALS_H

if defined(ARDUINO_ARCH_SAMD) || defined(ARDUINO_ARCH_ESP32) || defined(ESP32)

define MT_WIFI_SUPPORTED

else

define MT_SOFTWARESERIAL_SUPPORTED

endif

and it mt_serial.cpp

include "mt_internals.h"

ifdef MT_SOFTWARESERIAL_SUPPORTED

include

SoftwareSerial *serial;

else

define serial (&Serial1)

endif

void mt_serial_init(int8_t rx_pin, int8_t tx_pin, uint32_t baud) {

ifdef MT_SOFTWARESERIAL_SUPPORTED

serial = new SoftwareSerial(rx_pin, tx_pin); serial->begin(baud);

endif

ifdef MT_WIFI_SUPPORTED

mt_wifi_mode = true;

else

mt_wifi_mode = false;

endif

mt_serial_mode = true; }

Also was experiencing this issue. This did not work for me, and instead resulted in a cascade of errors:
