SoftSerial

[arnoldg]

Hello,

I'm trying to develop a dimmer which is controlled by serial.
For this i use softserial on puin D1 and D2
But when i compill all looks good, but it isn't working.
What could be wrong ?

for testing purpose the esp should spit out the whole alfabet, but this isn't working.
on the TX and RX pin's i connected a serial to USB print to monitor the serial port.
and yes TX and RX are connected the right way.

this is when i upload the softserial example it is working !

Is i2c activated on D1+2? That would be the default settings
