		+	Patogus interfeisas, debuginti nutolusius įrenginius, paprasta kaip du pirštus...
		+	* Perflashiname
		+	* Atresetiname
		+	* Pajungiame UART prie norimo įrenginio naudodami pinus RX (PIN G16) TX (PIN G17) jungiant prie kitų uart įrenginių reikia sumaišyti TX/RX vietomis. Taip pat pajungti GND ir jeigu reikia maitinimą 3V3.
		+	* esp32 prisijungęs prie wifi bus pasiekiamas per mdns kaip '''wifi-serial'''.
		+	* Jungiamės '''telnet <esp32-hostas-wifi-tinkle> 23''' t.y '''telnet wifi-serial 23'''
		+
		+	[https://www.arduino.cc/en/software Arduino IDE] reikia sudiegti papildomus [https://docs.espressif.com/projects/arduino-esp32/en/latest/installing.html esp32 boardus], pasirinkti tools > Board > ESP32 Arduino > ESP32 Dev Module. Prijungti esp32 microusb kabeliu ir pasirinkti portą tools > port. Tuomet Sketch > Upload.
