B4R Question Arduino + MCU ESP8266 with rSoftwareSerial.

I am unable to connect an ESP8266 MCU on arduino UNO with rSoftwareSerial.
It seems that the rSoftwareSeria library does not work in ESP.
Everything works fine on Arduino UNO (Pin 10 and 11). In ESP8266 the only pins that
I can use are RX and TX (pins 1 and 3) but I need to use pins 13 and 15. Does anyone have any ideas?

Did you use EspSoftwareSerial? Were you able to make it work with BR4?

... check, if pins you use are able for pwm... .I use D1 and D2 at D1 mini, but mcu may b different. Probably, you need d1 As D1Pins library for mcu too (Private d1 As D1Pins). So you dont initialize Softserial1.Initialize(57600, 1,2) but Softserial1.Initialize(57600, d1.d1,d1.d2)
