Hi,
I tried your code with NodeMCU and Wemos D1 without success.
I can only get data of "status", "uptime" and "wifi", from the device with MQTT Explorer but no other topics are provided.
I also tried to invert TX, RX and powering MAX2323 with 3v3 and 5V, moreover I tried every protocol (PIP, PCM, MPI) but nothing.

What am I doing wrong?
