when I printf using the \r option only nothing goes to the terminal.
I want to be able to print on the same line without a CR.

for (int i = 10; i >= 0; i--) {
printf("Restarting in %d seconds...\r", i);
vTaskDelay(1000 / portTICK_PERIOD_MS);
}

This prints nothing, even if I use fflush(stdout); after the printf.

Anyone have any ideas to do this ?

Maybe you can try ESP_LOGI() instead of printf(). (but my printf() is fine).

You can try ANSI codes, like

ESP_LOGI() wont work because all the ESP_LOGx's slap a CR at the end of what your printing.

printf("... \033[1G"); // Move cursor to column 1

Thanks, but the issue is without the \n the uart never shoots anything out. It gets buffered to some length, and when that buffer gets full everything gets dumped at once. I need a way to force the uart to dump what it has.
