ESP32 full 2 ways communication between the DEVKIT and PC / MOBILE via USB cable - without using the fprint command

[Eldad Wasserman]

Hi,

I will be happy if someone can help me with some basic help. 

I need that:

1. The MCU will not send anything via the USB serial port while it's booting - nothing...

2. To communicate without any "external logic" between the PC / mobile USB cable and the ESP32 directly byte after byte. without using the fprint function...

I developed a solution with Arduino-ESP and everything is working perfect. read from IO - output to IO full serial communication with the USB serial etc... now I am trying already 3 days to migrate this ARDUINO-EPS solution to ESP-IDF  - amazing how it's difficult and not easy to do.

If someone here can help me -

Thanks

Eldad

Hi Eldad

You can configure which UART is used for console via 'make menuconfig'. It's in Component Config->ESP32-specific->UART...

If you switch the console to another UART you cant then send your data over UART0 (see esp-idf examples).

In general, not many people use ESP32 here. For non-BTstack related ESP32 questions, you're probably better of with their forum or the IRC channel.

Best
