I have some doubts regarding usage of tx and rx of uart0. Please, would anyone help me?
Here is the doubt: I need to use an uart to communicate heltec wifi lora v2 module to an external board. Considering heltec lora wifi v2 schematic, uart 0 is the uart wired to tx and rx in pin headers (identified as tx and rx). However, usb / uart converter cp2102 uses uart 0 too (to communicate a pc with the board and write firmware to esp32).
As uart 0 is the only uart available to user in this module (uart 1 is for flash and uart 2 pins are being user to another module features), can I use uart 0 WITHOUT taking risk of cannot write firmware to esp32 no more (I mean, use uart 0 and don’t make the esp32 unflashable again)? If yes, how can I do that?
Thanks in advance.
