I want this connected to my controller by Wifi, and have a few Wemos D1 mini boards laying around.
First i thought i'd just connect the USBs together and load ESPLink. No game, as the ESP didnt deliver power to the RFX.
I then tried to connect it at the 5V and RX/TX pins, and got som LED activity on the RFX, but no communication. After some fiddling around swapping RX/TX i got a few messages through, but no stable connection.
What am i doing wrong here? USB Serial levels are compatible with the RX/TX on the ESP right? Any other SW than ESPLink to try?
Any help is appreciated!
