back to serial swap:
I have connected my IR-R/W-Unit to TXD2/RXD2 (IO15/IO13).
#define ITFserial Serial ...... ITFserial.begin(9600); Serial.swap();
thats IMHO all code I need.
BUT. its not working proper. If I disconnect the TX/RX wires, start the ESP and connect the two wires its working. With fully connected IR-unit, the ESP fails to start, and the IR-TX-LED is always ON.
Something, I do not see?
Any kind soulmate to help me?
Dear Friends, I have a problem that it drive me mad! Tested In several ESP8266 Based on ESP-12F modules all the same problem, I running my sketch that is Arduino ESP8266 Core 2.3.0 ( also tested with the git recent version, same problem... ) based mostly used Blynk 0.4.7 library. When I running the module(s) at my home using TpLink 4G router M7350 UN then keeping printing the ESP Free Heap this memory always auto reduced without a reason... WITH Exactly the same hardware/software , when I move the setup to my works WiFi THEN I HAVE NOT any ESP Free Heap memory "Auto" reduction... I can suppose that something is wrong in the TCP/IP stack but I am not software engineer. Please try to help me. The important point is that with all the same except the routers the behaviour changes dramatically from working OK ( when at work WiFi ) to very fast heap auto reduction ( when at home with 4G router ).

Hi, need some help/ideas...
Have a Wemos D1. Using Serial1(TX1) for debug messages. Code is reduced for testing to only these two lines in setup()
Serial1.begin(115200); Serial1.println("---------------- PROGRAMMSTART ---------------------");
The ESP is powered by the USB-cable. When I power up the ESP (plug in the USB-cable in the USB-Port of my computer) the ESP is starting and I get the "PROGRAMMSTART-message". But after this there are some funny characters sent out to Serial1, and the ESP is freezing. A screenshot of the characters is in the top of this post.
After flashing, or after pressing the reset-button ESP is working fine.
Any ideas? thx in advance
