#46307 Maybe you need to revise your wiring. Do you have a scope or a logic analyser to see the signals ?

Beware that connecting UNO with ESP, if conections are TX/TX and RX/RX or TX/RX and RX/TX, both are different scenarios : one is connecting the ESP to USB while the other is connecting ESP to ATMega328, you can NOT have both at the same time.

About the code I've provided, I'm using it for Telnet Server on ESP since almost 18 months, so it has been tested a lot ;)

#46371 Thank you Mr.Martin,

So I am to understand that unplug the USB cable and power my esp and arduino from a independent power source..?

Also what are the limits for voltage and current I am supposed to look for on my esp8266 RX channel?
to make sure data is being written.
