ESP32 UART control

Postby Autom8n » Wed Jul 24, 2019 1:39 pm

Please excuse my ignorance on the subject but is there any way outside of the application program to disable the UARTs? After the initial program is loaded into flash, I want to disable the ability to read/write via uart permanently. Is this possible?

No, not really. There is a bootstrap pin that suppresses boot rom UART output, but the rest of the suppression you'll have to do in your application.
