# ESP32-Serial-Bridge

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.

===============================================================

Used Libraries: (must be installed in the arduino IDE):

===============================================================

In some cases the memorylayout is to small for this scetch.
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:

# Hardware
here is the wiring diagram recomendation:

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 straigt forward (other PINs are marke as Rx/Tx), but this assignment allows to flash via USB also with hooked MAX3232 serial drivers.

I recomend to start your project with a Node32s or compatible evaluation board. For a TTL to RS232 level conversion search google for "TTL RS3232 Converter"
