Hi,
I have a specific question about using UART communication with Wemos D1 R1.
I have an Ultrasonic distance sensor which works well with Arduino Mega/ UNO etc. It is based on serial receive.
The problem is I never had success using such boards with ESP based boards like WemosD1R1, ESP8266 generic, etc.
Do you know any useful tips/libraries/tools to make it work?
