Debug Serial over WiFi (Serial2Telnet)

[arjen1]

Since I have several projects far away from my PC and also a laptop will not suffice, I wrote some software to debug anything with RS232 output over the air.

Essentially a Serial to Telnet Interface.

You'll need a NodeMCU/ESP8266. Might work with ESP32 (Not Tested).

Just connect your projects' RS232 TX output to the RX input. You also need GND of course.
Power externally with a battery(pack), PSU or from your project if it has 5V or 3V3

Starts with a WifiManager. Connect to this AccessPoint with your phone/tablet. Enter the IP credentials of you network.

You can set the Baudrate via Telnet.
