Hi all!
I want to share my experience of dongle building. I used Wemos D1 mini and spent few days trying to make it work. Bad choice, here is information: https://www.element14.com/community/thread/77097/l/wemos-d1r1esp8266-uart-communication
Wemos D1 mini has only one fully-functional UART that is already occupied by USB-to-Serial onboard converter. So I had to use software UART:

uart:
  tx_pin: 5
  rx_pin: 4
  baud_rate: 9600

It works finally.
