Wifi to 3x Serial and one BT bridge based on a ESP32 with configuration website
Transparent WiFi (TCP) to all three UART Bridge, supports both AP and STATION WiFi modes. The .ino file is the code for the ESP32. Use Arduino IDE for ESP32 to compile and upload it to the ESP32. I made this project in order to connect Flight equipment devices devices like (Radio, Vario FLARM), to a Flight Computer (Kobo, Smartphones etc.), but it is not limited to that. You can use it wherever you want, but on your own risk. Read license file for more details. Accesspoint
This is the advanced version of the ESP32-Serial-Bridge, now with a configuration website. It allows the entire configuration, NMEA Filter and cross serial data exchange. All configurable in the website.

In some cases the memory layout is too small for this sketch. If you face this problem you can either disable Bluetooth by removing #define BLUETOOTH in config.h or change the partition size as described here: https://desire.giesecke.tk/index.php/2018/04/20/change-partition-size-arduino-ide/

Hardware:
here is the wiring diagram recommendation:
https://raw.githubusercontent.com/AlphaLima/ESP32-Serial-Bridge/master/ESP32-SerialBridge.jpg
Pinning:
COM0 Rx <-> GPIO21
COM0 Tx <-> GPIO01
COM1 Rx <-> GPIO16
COM1 Tx <-> GPIO17
COM2 Rx <-> GPIO15
COM2 Tx <-> GPIO04
NOTE:
The PIN assignment has changed and may not look straight forward (other PINs are marked as Rx/Tx), but this assignment allows to flash via USB also with hooked MAX3232 serial drivers.
I recommend to start your project with a Node32s or compatible evaluation board. For a TTL to RS232 level conversion search google for "TTL RS3232 Converter"
